Yr Eifl

The Lleyn

This is an impressive cliff consisting of 5 Buttresses spread along the coast south west of Trefor on the Lleyn Peninsula. No. 5 buttress is the largest and contains the classic Avernus. These make up the biggest coastal cliffs in Wales however arguable also the most grass. 

There has been some recent development on the cliff, and a few new routes have filled some of the gaps between some of the impressive 200m routes.

We were approached on the walk back down through the Yr Eifl quarry inclines by a local resident who told us that the quarries are private land and we shouldn’t have been walking down there. The owner of the quarry wasn’t happy that we were up there. The guidebook currently has no mention of access restrictions but it seems like this is no longer the case!
