About this walk

The Snowdon Horseshoe is a hard 12 km circular walk with 1,020 m of ascent, taking 4.5 to 6 hours. It starts at Pen-y-Pass (grid reference SH 647 556). It climbs 4 listed hills, the highest Yr Wyddfa (Snowdon) at 1,085 m. The start can be reached by public transport.

The Snowdon Horseshoe circles Llyn Llydaw and Glaslyn below Yr Wyddfa, the highest mountain in Wales. It starts with Crib Goch, a narrow, exposed knife-edge ridge that's a grade 1 scramble: in wind or wet, it's genuinely dangerous.

From Crib Goch the route crosses Crib y Ddysgl to the summit of Yr Wyddfa, then descends the Watkin Path a short way and traverses the twin peaks of Y Lliwedd before dropping to the Miners' Track. Book parking at Pen-y-Pass in advance or use the Sherpa buses.
