The walk
The walk starts from the car park at Arthog, beside the Mawddach Trail on the south shore of the Mawddach estuary. A path climbs in the woods beside the Arthog waterfalls, a series of falls above the village, and goes on to Llynnau Cregennen, the two lakes the National Trust owns, with Cadair Idris in view. The line takes in the top of Pared y Cefn-hir, 383 m, for the view over the estuary, then follows paths and lanes north-east down to Abergwynant, where the old railway is now the Mawddach Trail. The trail brings you back along the estuary to Arthog.
It is 15.3 km with 453 m of ascent; allow about 5 hours. The grade is Moderate.
The Park Authority says the walk includes steep or unsurfaced paths in open country, and that boots and waterproofs are essential. About a fifth of the way is on lanes, and the Mawddach Trail is shared with cyclists. There is no café or shop on the hill section.
OpenStreetMap shows no charge at the Arthog car park, which the National Park Authority runs. Morfa Mawddach railway station, on the same trail, is about 1.3 km from the start.
