This is a short stretch of 3.5 miles with lovely views over the Dart as well as Torbay. A Google Earth view opens in a separate window. I started after catching up with Gary and Kay Deare in Galleon Post Office and Stores. I have posted Gary's suggestions for improving the profitability of post offices on the chat map; well worth a look.
Head down the road past the post office and turn left at Manor Farm, taking the lane towards Galmpton Creek. After a short section along the beach turn inland following the well marked footpath and through a beautiful farmyard. Carry straight on over the road continuing uphill and through the woodland. Turn right as you come out of the trees and follow the path until it divides. Turn left towards Maypool and left again when you hit the track. After about 500 meters, turn right towards Higher Greenway where you keep left. After another 500m turn left onto the John Musgrave Heritage Trail. After about 1km turn left over the railway bridge and head back to Galmpton.
If you have more time, this circuit can be extended to include a loop through Churston and Broadsands. The River to Sea route, which is about 6 miles, the views are stunning and Galmpton has two good pubs to call into on your return.
