Grey Mare's Tail & St Mary's Loch
A708Moffat to Selkirk
A wild Borders road past a hanging waterfall and a lonely loch.
The A708 runs from Moffat over the hills past the Grey Mare’s Tail waterfall and along the shore of St Mary’s Loch towards Selkirk, one of the finest roads in the Southern Uplands. It is narrow and exposed in places with sweeping bends; watch for sheep, walkers at the falls and weather over the tops.
