Walking The Hertfordshire Way through the Chilterns

Near Flamstead


The Hertfordshire Way offers an incredible opportunity to circumnavigate one of England's home counties, revealing its hidden charms and surprising variety. This circular long-distance footpath, stretching around 273 km (170 miles), guides walkers through the county's most picturesque landscapes, proving that green spaces are never far, even in this area close to London.

Beyond the stunning rural vistas, the Hertfordshire Way is a journey through history and charming local life. The route intentionally keeps mostly to the quiet countryside but thoughtfully incorporates visits to a handful of attractive, historic villages and two major centres: the county town of Hertford and the ancient city of St Albans, with its stunning cathedral and Roman heritage. Along the path, you'll encounter a mix of landscapes, from the fringes of the Chiltern Hills near Tring, to the wide views around Royston, and the peaceful valleys further east.

We walked the Chilterns part of the Hertfordshire Way in 15 sections over a couple of years. We used my “Greater Chilterns” definition that takes the trail from the River Lea near Wheathampstead to the River Colne near Garston. The part of the trail that runs through the Chiltern Hills National Landscape (formerly “AONB”) is much shorter and runs from Markyate to Berkhamsted.

Walking the Hertfordshire Way in the Chilterns in 15 walks

If you’re not up for a 82 km walk in one go, you can take in the Hertfordshire Way in the Surrey Hills in 15 walks of between 8 and 14 km each. We chose this option, completing all 15 sections over 4 years from 2021 to 2025. The advantage of this option is exploring more of the villages and side paths close to the route.

As the complete Hertfordshire Way is a circular route you can walk it in either direction. The roundels on the route show whether you’re heading clockwise or anti-clockwise on either side of the footpath posts. For our short walks linked below we did a mix of clockwise and anti-clockwise and I’ve indicated the direction in the list below. If want to complete them in a consistent direction you’ll need to reverse the route for some of them.

Completing all Warwickshire parkruns

There are currently 6 parkrun events in present-day Warwickshire of which I have not yet completed any. There are a further 6 parkrun events in the part of the Historic County of Warwickshire which are now in the present-day Ceremonial County of West Midlands.

The first event in Historic Warwickshire was Coventry which started on February 6th 2010. The newest is Holbrooks which started on August 5th 2023. I’m not aware of a collective name for having completed all Warwickshire parkrun events, but let me know in the comments below if you know of one.

Numbers exclude any events that are not open to the general public such as prisons or armed forces facilities.



The interactive maps below take you to the approximate location for the course, typically the centre of the park. See the course instructions in the parkrun page for each event for specific directions to the start. Course maps show the route at the time that I ran it and may have changed since then.

This circular long-distance footpath, stretching around 273 km (170 miles), guides walkers through the county's most picturesque landscapes, proving that green spaces are never far, even in this area close to London. We walked the Chilterns part of the Hertfordshire Way in 15 sections over a couple of years. We used my “Greater Chilterns” definition that takes the trail from the River Lea near Wheathampstead to the River Colne near Garston. This route is one of those 15 circular walks.

The guidance below will help you navigate but don’t use it as a fully accurate turn-by-turn guide. Always take a map and/or a GPX route and prepare well for the weather and terrain.

We parked at the end of the route at Aldenham and took an Uber to the start of the walk at King’s Langley. You can also do it by a combination of a bus to Bushey and a train to King’s Langley but it was a mid-winter’s day and we were short on time.

Exit from the eastern side of King’s Langley station and walk north past the car park to reach Egg Farm Lane. Take a right to follow the lane up the hill and over the M25. At 1.5 km into the walk you’ll reach a path junction at the corner of a field. Take a left to follow the field-edge path in a north easterly direction. Take a right onto Bedmond Road then a left onto Love Lane. Keep heading east as Love Lane turns into a path crossing fields. Keep following the Hertfordshire Way until you reach Chequers Lane.

Briefly follow Chequers Lane in an easterly direction then take the first path on the right heading south to High Elms Lane. Take a left to follow High Elms Lane to the A405 North Orbital Road. Take a right to find the underpass then cross under the A405. Follow Bucknalls Lane in an easterly direction, crossing over the M1 bridge. Near the end of Bucknalls Lane before it becomes Oaks Path, take a right to keep on the Hertfordshire Way through Bricket Wood into the Munden Estate.

Once in the Munden Estate look out for the path on the right cutting diagonally across the estate in a southerly direction. This will lead you onto a footbridge over the River Colne. This is the eastern boundary of the “Greater Chilterns Area” and nearly the end of the Chilterns section of the Hertfordshire Way. After the Colne continue following the Hertfordshire Way for 1.7 km until you reach St. John The Baptist Church in Aldenham Village.

Gorleston Cliffs

Gorleston-on-Sea, including its iconic cliffs, was historically part of Suffolk, with the traditional county boundary running along the River Yare and Breydon Water, placing the land to the south (Gorleston) firmly within the northern reach of Suffolk. This historical county division was noted as far back as the Domesday Book. However, as the port of Great Yarmouth (which was in Norfolk) expanded and became the dominant civic and economic centre of the area, the administrative geography was adjusted. Gorleston was first brought into the Great Yarmouth parliamentary constituency in 1832 and officially incorporated into the Municipal Borough of Great Yarmouth in 1836 under the Municipal Corporations Act 1835. While the borough itself straddled both counties for a time, a final administrative change in 1891 placed the entire borough, including Gorleston, entirely within the county of Norfolk, thereby moving the coastal cliffs permanently to their current county

Other routes touched (walk): Capital Ring, Thames Path
Other routes touched (cycle): C40, Grand Union Canal Towpath

In the heart of West London, Ealing is famed for its leafy suburbs and Victorian charm. But for those seeking a true escape, look no further than the Brent River Park Walk. This green corridor, tracing the meandering path of the River Brent, offers a surprisingly wild and tranquil journey right on your doorstep.

The Brent River Park is the result of dedicated campaigning by the Brent River and Canal Society (BRCS) to protect the river valley. The resulting linear park stretches for approximately 7 km within the Borough of Ealing, encompassing about 400 hectares of green space.

Starting near Greenford and winding its way south towards Hanwell and the Grand Union Canal, the path connects several major open spaces, creating an uninterrupted haven for both wildlife and people. As you walk, you'll traverse a varied landscape—from formal parks like Pitshanger Park and Brent Lodge Park to stretches of wilder, almost rural-feeling woodland and meadows.

The walk is much more than just a riverside path; it's a journey past local history and nature. Here are a few highlights you can look forward to:

  • Brent Lodge Park and the Hanwell Zoo: A perfect detour for families, Brent Lodge Park is home to a small, popular zoo, locally known as "The Bunny Park."

  • The Grand Union Canal: The path eventually converges with the Capital Ring and the Grand Union Canal Walk, where you can watch the colourful narrowboats navigate the locks, notably the flight near Hanwell.

  • The Wharncliffe Viaduct: In Hanwell, keep an eye out for the magnificent Wharncliffe Viaduct, an impressive brick structure designed by Isambard Kingdom Brunel, carrying the Great Western Main Line over the valley.

The route is well-signposted, often sharing its way with sections of the Capital Ring, making navigation straightforward and allowing for flexible starting and finishing points.

As a flat, easy walk, you can do it all in a day, however we split it into 2 smaller walks of approximately 8 km with Hanwell Zoo as the split point. There’s a small free car park next to the Zoo on Church Road. Hanwell Station is on the Elizabeth Line and close to this mid-point of the route too. Although the river and the path end at the Thames we continued along the Thames Path to complete the walk at Kew Bridge Station.

This circular long-distance footpath, stretching around 273 km (170 miles), guides walkers through the county's most picturesque landscapes, proving that green spaces are never far, even in this area close to London.

The guidance below will help you navigate but don’t use it as a fully accurate turn-by-turn guide. Always take a map and/or a GPX route and prepare well for the weather and terrain.

For this walk we parked at the free car park on East Lane, Wheathampstead. Be careful not to use the car park next to it that is for customers of the Bull Pub. Walk in a southerly direction down Wheathampstead High Street, continuing onto the B651 “The Hill” for approximately 2 km until you reach the corner of Nomansland Common. Take a left onto a footpath just before Drovers Lane and follow it in an easterly direction through fields, across Coleman Green Lane and into Heartwood Forest. After passing through the farm buildings at Hammonds House farm you’ll reach the Hertfordshire Way at Hammonds Lane.

Take a left onto the Hertfordshire Way, following it in an east/north-easterly direction. After ~300m leave take the footpath on the left to leave Hammonds Lane but keep on the Hertfordshire Way. Follow the edge of the woods for ~700m then take a left to leave the tree line and continue along the Hertfordshire Way across the fields to Coleman Green. Just under 1 km from Coleman Green take a right onto Devil’s Dyke Lane. You can continue along the Lane, but I highly recommend finding the path on the right running through Devil’s Dyke. This is the remains of a prehistoric defensive ditch which is generally agreed to have been part of the defences of an Iron Age settlement belonging to the Catuvellauni tribe of Ancient Britain.

At the end of Devil’s Dyke Lane cross over Marford Road and continue along Sheepcote Lane until you reach the River Lea. The river is the boundary of what I call the Greater Chilterns Area and and is the final part of this series of walks along the Chilterns part of the Hertfordshire Way. There’s one final surprise in this walk though. North of the River Lea take a left onto the Ayot Greenway. This is part of a disused railway path that connects Wheathampstead to Welwyn Garden City. We’re following a short section of it as it runs parallel to the River Lea to the remains of Wheathampstead Station. The Station is worth a visit as it’s been nicely preserved with information boards describing its history. After the station walk down Station Road to cross over the River Lea and back to the start of the walk.

Trig Pillar Extremes

If you’ve searched for or stumbled across this page then you probably already know what an OS Trig Pillar is. If you don’t then this article from the Ordnance Survey is a good place to start.

Over 6,000 Trig Pillars were erected across the country from 1936 to 1962. The first known person to have visited all of them was Rob Woodall who completed his 14-year personal quest in April 2016. At the time of writing this I’ve also been visiting Trig Pillars for over 14 years but so far I’ve bagged less than 5%. While I don’t have the need to bag them all, I’d be happy with an “interesting 10%”. These would include all of the pillars on the UK County Tops and, as it’s close to home, all of South East England. After a geeky pub conversation somewhere in Scotland after a County Top climb, I also took an interest in the extremes: the oldest, the newest, the furthest north, east, south and west. This post shows the results of my research so far into what are those extreme Trig Pillars.

Let me know if you have any corrections to the information on this page or any suggestions for other extreme Trig Pillars. I’ll donate £1 to one of the outdoor causes that I support for any edit made.


Trig Pillar Compass Club

The spreadsheet below shows the same Trig Pillars as in the map above. Note that those highlighted in yellow are ones that I’m less confident in. Comment below if you can confirm or correct any of these.

Cycling The Horton Brook and Datchet Common Brook

Black Park Lake on the Horton Brook



It had been a few years since I thought that I had completed all of the Chiltern and Colne Valley rivers. Then I discovered the Horton Brook and The Datchet Common Brook on a map and needed to explore them too. Both are small and easily missed unless you’re looking out for them. They snake through fields and residential areas to the east of Slough but you can walk or cycle fairly close to them if you know where to look. Both of the brook’s sources are close to each other at Fulmer and and have confluences with the Thames near Wraysbury. This means that both can be discovered in a 40 km cycle ride, following the Horton brook from the source then the Datchet Common Brook from its confluence back to the source.

 

Cycling the Horton Brook from the source to the confluence with the Thames

River start: Boundary of Black Park and Pinewood Studios, Fulmer
River end: Confluence with the River Thames in National Trust, Ankerwyke
River length: 19.7 km (12.2 miles)
Links: DEFRA: Horton Brook

We started our cycle trip at the north-eastern corner of Black Park at the junction of Fulmer Common Road, Alderbourne Lane and Pinewood Road. Different maps show the source of the Brook either right on this corner or a little further south along the boundary of Black Park and Pinewood Studios. I’ve been cycling and walking there for years but always thought that it was a ditch.

After ~700m from Fulmer Common Road, the Brook cuts diagonally across the Country Park to empty into Black Park Lake, emerging on the south western side near the path to the car park. After Black Park the Brook crosses under Rowley Lane and into Rowley Farm. We cycled through the farm on the Rowley Farm Trail but ended up taking a fairly convoluted route to not stay very close to the Brook. The easiest route is to follow the A420 to George Green, although be very careful here is it’s a busy dual carriageway.

After the A420 the Brook snakes through George Green, Middle Green, across Langley Park Road and under the Grand Union Canal Slough Arm. Cycling close to the Brook is pretty straightforward and there’s a nice straight section of the canal to follow. After leaving the canal at Mansion Lane you’ll cross uner the railway and take a left onto Parlaunt Road then right onto Old Slade Lane. Meanwhile, the Brook passes through a field and Ritchlings Park Golf Club. After crossing over the M4, leave the Colne Valley Trail at a footpath junction and follow a messy path initially parallel to the motorway then cutting through a field to cross over the A4 Colnbrook Bypass. Here you’ll briefly re-join the Colne Valley Trail through Colnbrook village. After Colnbrook follow Horton Road keeping the Brook and The Queen Mother Reservoir on your right. Cross over Datchet Road to follow Park Lane and onto the footpath through the lakes to Station Road.

At Station Road you can take a left heading east to the bridge where the Brook flows under and into Wraysbury Lake. According to the DEFRA site, this is where the Horton Brook ends. The Wraysbury Lakes Ditch takes water from the lake and into the Colne Brook, which itself flows into the Thames at Runnymede.

For a more interesting cycle ride we took a right onto Station Road, passing through Wraysbury High Street then took at right into Magna Carta Lane. Here you can pass through the National Trust Ankerwyke site to connect to an arm of the Horton Brook that joins the Thames to the east of Ankerycke Yew. The paths through the National Trust site are for walking so best to lock your bikes up at the parking area.

 

Cycling The Datchet Common Brook from the Thames to the source

River start: Fulmer Wood Lake, Slough, SL3 6AA
River end: Confluence with the River Thames near The Avenue, Sunnymeads, Wraysbury, Staines, TW19 5EY
River length: 11.3 km (7 miles)
Links: DEFRA: Datchet Common Brook

From the end of the Horton Brook return to the B376 Staines Road and take a left towards Wraysbury. At the mini roundabout continue on the B376, then take a left onto The Avenue at Sunnymeads. Look out for the bridge over the Datchet Common Brook near house #37. This is the closest you’ll get to the confluence with the Thames which is behind the houses on the western side of the road.

After the bridge, turn around and take the next left onto Acacia Avenue to Sunnymeads Station. Take the footpath on the right to climb the steps back up to Welley Road. Take a left and follow Welley Road to the junction with Datchet Road. Take a left onto Datchet Road and follow it in an easterly direction towards Datchet Common. The Brook follows the Datchet Road on the northern side, following the edge of the Queen Mother Reservoir.

Take a right onto Penn Road, a left onto New Road then a right onto Ditton Road. Take a right at the junction with Major’s Farm Road, running parallel with the M4 until you reach the footbridge. Cross the bridge over the motorway to the northern side and look out for the entrance to Ditton Park on the corner of Ridig Court Road and Ditton Park Road.

You’re now in the most enjoyable part of the ride, following the course of the Brook through Ditton Park to Upton Court Road. At the north-eastern corner of Upton Park, take Quaves Road onto Lascelles Road then take a left on the A4 Wellington Street, crossing over to the northern side where safe to do so. At the large Sainsbury’s Roundabout take the A412 heading north. After crossing over the railway line and canal you can follow the quieter residential roads that run parallel to the A412.

Take a left onto Church Lane then a right onto Wexham Park Lane. Look out for the bridge over the Brook at Valley End at the bottom of the hill. Shortly after Valley End, at a curve in the road, take the footpath on the left called Gallions Lane and follow it in a northerly direction. The Brook will now be on your left running through Wexham Park Golf Course. Just before the end of Gallions Lane take a right to follow the path running parallel to Rowley Lane to the end at Black Park Lane. Follow Black Park Lane in a northerly direction to the end at Fulmer Common Road. When you meet the Shakespeare’s Way and Beeches Way that join from the left you’re now as close as you’ll get to the source of the Datchet Common Brook at Fulmer Wood Lake.

Take a right onto Fulmer Common Road to return to the start of the cycle ride at the north-eastern corner of Black Park

The Hertfordshire Way offers an incredible opportunity to circumnavigate one of England's home counties, revealing its hidden charms and surprising variety. This circular long-distance footpath, stretching around 273 km (170 miles), guides walkers through the county's most picturesque landscapes, proving that green spaces are never far, even in this area close to London. We walked the Chilterns part of the Hertfordshire Way in 15 sections over a couple of years. We used my “Greater Chilterns” definition that takes the trail from the River Lea near Wheathampstead to the River Colne near Garston. This route is one of those 15 circular walks.

The guidance below will help you navigate but don’t use it as a fully accurate turn-by-turn guide. Always take a map and/or a GPX route and prepare well for the weather and terrain.

For this walk we parked at the free parking area on Nomansland Common off Ferrers Lane. Take the footpath heading west from the parking area and, after approximately 800m, take the southern footpath through the woods towards Round Wood. Keep heading in a south westerly direction along the field edge until you reach the railway embankment. Take a right to follow the right hand edge of the railway until you reach Ayres End Lane. Take a left to pass under the railway line, then the first path on the right to follow a path that bypasses Ayres End Lane and joins the Ver Valley Walk.

Follow the Ver Valley Walk in a south westerly direction. Carefully cross over the A1081 Harpenden Road and take a right into Childwickbury. Here you’ll join the Herfordshire Way. Take a left in Childwickbury village to follow the Hertfordshireway back to the A1081 Harpenden Road. Turn right onto the A1081 then carefully cross over to follow the Hertfordshire Way in an easterly direction to Sandridge.

Sandridge village is a good place to stop for a rest at 8 km in. There’s a few pubs and a cafe so it’s well-served for a small village. After Sandridge continue to follow the Hertfordshire Way in a north-easterly direction until you reach the junction with the Romans and Nomansland trail at Hammonds House farm. Leave the Hertfordshire Way here and follow the Romans and Nomansland trail in a north-westerly direction through the farm. Eventually you’ll cross the Wheathampstead Road back onto Nomansland Common and the final short section back to the car park.

The guidance below will help you navigate but don’t use it as a fully accurate turn-by-turn guide. Always take a map and/or a GPX route and prepare well for the weather and terrain. For this walk we parked at the Verulamium Car Park on the western edge of the town. The location is great for the walk but it’s also expensive. There’s other parking and public transport options in St Albans though.

Most of this walk is in the countryside to the north of the city, however there’s a “bonus” loop of 2.5 km that takes in St. Alban’s Cathedral, Fishpool Street and Verulamium Park. It’s worth doing but if you want to skip it the main section of the walk is around 11.5 km. My advice is to do the main section first then have a rest in one of the city’s pubs and cafes then do the small loop before returning to the car park.

For the main section of the route, exit the car park on the western side onto St Michael’s Street then take a right onto the A4147 Hemel Hempstead Road. It’s a busy route into the city but the pavement is safe enough and it’s a short distance. After the roundabout carefully cross over and take the first lane on the left heading into farmland in a north-westerly direction. Follow this path through fields, woods and a golf course to the small village of Childwickbury.

Continue through Childwickbury until you reach the A1081 Harpenden Road. Take a left onto the A1081 and follow the pavement for 1.2 km then take a left onto Beesonend Lane. Follow the lane for 2 km in a south-westerly direction until you reach a T-junction with a path that runs parallel to the river Ver. Take a left to follow this path in a southerly direction to the A5183 Redbourn Road.

Cross over the road and enter a gate into the Gorhambury Estate. Follow the path through the estate until you reach the A4147 Hemel Hempstead Road. Cross over the road to return to St Michael’s Street and the car park. Note that Gorhambury is a private estate with permissive paths running through it. The gate from the A5183 was locked when we were there so we had to take a less interesting diversion along the A5183. Check the Gorhambury Estate website for details of any closures.

For this walk we parked at the free car park on West Common near the cricket club. Walk along the tree-lined avenue in a south-westerly direction then take a right onto Flamsteadbury Lane. Take a left onto Ben Austins (road) and then a right onto the footpath next to house number 13. When you reach the field corner take a left to follow the Hertfordshire Way in a south-westerly direction along the field-edge. Keep following both the Very Valley Walk and Hertfordshire Way to pass through the grounds of St Mary’s Church, across Hemel Hempstead Road and onto the Nickey Lane disused railway.

Take a left onto the Nickey Line and follow it for 1.8 km until you reach a path junction just after crossing over the River Red. Take right at this path junction to leave the Nickey Line to stay on the Hertfordshire Way. Follow the Hertfordshire Way in a south-easterly direction for 2.6 km as it runs parallel to the River Ver. Approximately 0.5 km south of the Redbournbury Watermill leave the Hertfordshire Way to cross over the River Ver into a cow field. There’s a section of stepping stones where you can cross an arm of the Ver after the footbridge.

Cross the cow field and over the A4183 Redbourn Road then onto Punchbowl Lane. Follow Punchbowl Lane in a south-westerly direction for 3.3 km then take the footpath on the right to follow the Ver Valley Walk across fields in a northerly direction. Keep on the Ver Valley Walk heading north for approximately 3 km back to the start at West Common.

South West England parkruns

The parkrun Regionnaire status used to be a major part of parkrun tourism, with South East England being the largest region. Changes in the parkrun website in 2019 removed the regions making it harder to track completion status. All is not lost though as here’s the complete parkrun guide to what’s in and what’s out of the counties of South West England.

The South West England region is the largest of England's nine regions by area, encompassing the historic and ceremonial counties of Cornwall (including the Isles of Scilly), Devon, Dorset, Somerset, Wiltshire, Gloucestershire, and the city of Bristol. It stretches from the border with the South East and West Midlands, down to the far southwestern tip at Land's End, giving it the longest coastline of any English region. The area is often romantically referred to as the West Country and includes ancient landscapes such as Wessex. The key urban centres are the thriving city of Bristol, the historically important naval port of Plymouth, and the coastal conurbation of Bournemouth/Poole.

Map of South West England showing the Historic and present-day (Ceremonial) counties


parkrun event numbers per county

There are currently 86 parkrun events in the South West region. Three of these events were in Hampshire in South East England before the county boundary changes in 1974, however this was a long time before parkrun started. There are currently no parkrun events in the present day / Ceremonial county of the Isles of Scilly


Notes and exceptions.

  • Numbers of event above exclude prison parkruns and permanently cancelled events.

  • Bournemouth and Moors Valley parkruns were part of Historic Hampshire and would have been in Historic South East England, but are now part of Present-day Dorset, so would be in the South West England region.

  • Tidworth: South Tidworth where the parkrun takes place was moved from Hampshire into Wiltshire in 1992 but houses there still have Hampshire on their address for post.

  • The course for Tamar Lakes is in both Cornwall and Devon however the start and finish are on the Cornwall side so I’ve included it there.
