The Snowdon Horseshoe is the most famous mountain route in Wales — a full-day circuit over the ridges and summits surrounding Yr Wyddfa (Snowdon). Beginning at Pen-y-Pass, the path climbs the knife-edge of Crib Goch, continues over Garnedd Ugain and Yr Wyddfa, and returns via Y Lliwedd, forming a perfect “horseshoe” around the glacial lakes of Llyn Llydaw and Glaslyn.
It’s a route for experienced walkers and scramblers, blending high adventure with extraordinary mountain scenery. On clear days, views extend across the Irish Sea, Anglesey, and deep into the heart of Eryri National Park.
The Snowdon Horseshoe can be walked independently in a single day or as part of a guided or self-guided walking holiday that includes accommodation in Llanberis, Beddgelert, or Betws-y-Coed.

This is a serious mountain route that requires confidence on exposed terrain and good navigation skills. Weather can change rapidly, and the Crib Goch ridge in particular should only be attempted in dry, calm conditions. Proper boots, warm clothing, and a map and compass are essential — even in summer. For less experienced walkers, guided and self-guided holidays offer a safer, supported way to complete the route.
