The Trail follows river valleys, ridge roads, open downland and woods away from the northern edges of Dartmoor, linking the imposing Norman castles at Okehampton and Launceston. The Trail is coincident with the West Devon Way between Okehampton and Bridestowe. The Trail links with the Tamar Valley Discovery Trail and the West Devon Way to form a circuit of approximately 90 miles, dubbed the ‘West Devon Triangle’.
