Crib Goch

Crib Goch is the knife edge that opens the Snowdon Horseshoe, and it is the most exposed Grade 1 on this list. The moves are simple; the challenge is keeping calm with serious drops on both sides of the crest. You follow the Pyg Track briefly before scrambling onto the ridge, and beyond it the horseshoe continues to Yr Wyddfa and over Y Lliwedd. High winds are the real hazard, so save it for a calm day, and snow makes it significantly harder. The full horseshoe is about 11.5 km. Pen y Pass parking is small and fills fast, and between spring and fall it is worth checking whether it needs booking ahead; the Sherpa'r Wyddfa bus is often the easier way to the start.
