About Y Lliwedd

The birthplace of British rock climbing — the Victorian pioneers cut their teeth on Y Lliwedd's vast north face before moving on to the greater ranges. The highest cliff in England and Wales sits on the eastern arm of the Snowdon Horseshoe above Llyn Llydaw. A serious mountain venue with a reputation for tricky route-finding, sparse protection and being hopelessly slippery when wet — needs a proper dry spell and settled forecast. Approach by the Miner's Track from Pen-y-Pass in around 90 minutes.
