The trail begins in Oughterard and follows the Lough Corrib shoreline for some ten kilometres north west toward Maum. A few kilometres beyond Doon Rock the trail enters a forestry plantation and for the first time the sensation of remoteness will be experienced. The R336 brings the hiker over the pass and down toward Maum. The trail turns west 300 metres south of Maum Bridge.
Lough Corrib to the east of the trail is one of Irelands great lakes. It is the second largest lake in Ireland at 176 km². In places it is 47 metres deep. Wildlife in and about Lough Corrib includes hawks, otters, mink, stoat, frogs, and bats. Freshwater trout and salmon are fished for in the lake.
