This 16-mile trailway is suitable for walkers, cyclists and horse riders alike. It follows the route of the old Dorchester to Southampton railway, which was built in 1847 by Charles Castleman. The twisting stretch of track became known as the ‘Castleman Corkscrew’. The railway was closed in the 1960s by Dr. Beeching and the land sold. Public access has since been granted along the resurfaced path, which now takes visitors through some of Dorset’s most scenic countryside including heathland, mature pine forest and the River Stour valley.
