This is part of a series of short circular walks following the length of the Midshires Way in Buckinghamshire. The Midshires Way is a 225-mile (362 km) trail that journeys through the rural heart of Middle England, linking the Ridgeway National Trail at Bledlow in the south to the Trans Pennine Trail at Stockport in the north. Opened in 1994, this route traverses several counties, including Buckinghamshire, Northamptonshire, Leicestershire, Nottinghamshire, Derbyshire, and Greater Manchester, following a scenic tapestry of ancient bridleways, quiet country lanes, and historic canals. In Buckinghamshire, the Midshires Way has a significant connection with the Swan's Way (often referred to as the Swan Way), a 65-mile long-distance bridleway. Essentially, the Swan's Way forms the backbone of the Buckinghamshire section of the Midshires Way, with the two routes being broadly coincident for approximately 50 miles between Salcey Forest and Bledlow. While the Swan's Way strictly adheres to bridleways to accommodate horse riders and cyclists, the Midshires Way sometimes offers alternative waymarked footpaths for walkers to avoid on-road sections.
Walking Directions
This walk explores a fascinating slice of Buckinghamshire history, linking the ancient village of Stone with the grand estate of Hartwell House. The route offers a pleasing contrast between the open, agricultural landscapes typical of the Aylesbury Vale and the manicured, historic parkland of Hartwell, where you can spot 18th-century follies and a decorative bridge.
The path is generally gentle and well-marked, following a section of the long-distance Midshires Way before looping back through the quiet fields south of the River Thame. It is a walk that combines architectural interest with rural tranquillity.

Points of Interest along or near to the Route
Stone: This historic village sits on a ridge of limestone and sand, giving it its name. The parish church of St John the Baptist dates back to 1273 and features a remarkable Norman font with intricate carvings of humans and animals.
Hartwell House: A magnificent Grade I listed stately home that once served as the residence of the exiled King Louis XVIII of France. The parkland is dotted with 18th-century follies and monuments, many of which are visible from the public right of way. Look out for the estate walls; they are historically notable for being encrusted with fossils and rare stones.
The Egyptian Springs: A unique folly located near Hartwell House, commissioned by Dr John Lee in the 1850s. Designed by Joseph Bonomi the Younger, it features an Egyptian-style alcove and a Greek inscription which translates to "Water is Best"—a nod to Dr Lee's support for the temperance movement.
The Bugle Horn: Originally a farmhouse associated with the Hartwell estate, this building was converted into a pub in the 19th century. Its curved brick wall is a distinctive local landmark, said to have been built that way to prevent coaches from clipping the corner.
