Snowdon via Crib Goch: A Guided Traverse of Wales’s Iconic Knife-Edge Ridge
Select participants and date
Dawn leans over the Llanberis Pass and the rock wakes up first. Crib Goch sharpens in the light, a serrated skyline that seems to dare you forward. The approach from Pen-y-Pass is steady—slabs underfoot, the Pyg Track threading toward the ridge—until the terrain tips upward and the mountain shows its teeth. Here, stone demands focus. Gusts press and release, testing your stance. Move by move, the arête narrows to a balance beam with consequence on both sides, and confidence becomes a tool as essential as your boots.

Adventure Tips
Own the exposure
Crib Goch is airy and sustained. Move deliberately, keep three points of contact on the pinnacles, and don’t be afraid to shuffle below the crest when wind picks up.
Start early, think buses
Pen-y-Pass parking fills before sunrise on busy days. Use the Snowdon Sherpa bus from Llanberis or Nant Peris to guarantee a smooth start.
Weather decides the day
Strong winds or ice can shut down the ridge. Check the Met Office mountain forecast and be ready for route or date changes at the guide’s discretion.
Pack for high mountain conditions
Even in summer, carry a waterproof shell, warm layers, gloves, hat, 2L of water, and high-energy food. Conditions can swing fast on the Horseshoe.

History
Copper mining around Llyn Llydaw boomed in the 19th century, and the nearby Pen-y-Gwryd Hotel hosted and trained the 1953 Everest team. The Welsh name Yr Wyddfa remains central to local identity.
Conservation
Eryri’s paths erode quickly—stick to established lines, avoid shortcuts, and pack out all litter. Use public transport to reduce traffic over the pass.
