About Craig y Castell (Tremadog)

The third and westernmost of the Tremadog crags, above Tremadog village. Same golden dolerite and same south-facing rain-shadow position as Bwlch y Moch and Pant Ifan — famously quick-drying and reliable in dodgy weather. Quieter than its neighbours, with a run of superb lower- and mid-grade classics on perfect rock. Creagh Dhu Wall (HS 4b) is an all-time Tremadog classic; One Step in the Crowds (E1 5b), Tensor (E2 6a) and Pellagra (E3 6a) fill out the higher grades. Multi-pitch buttresses reach up to 70m. Park in Tremadog town square and walk up past the school and hospital.

Region: North Wales — Tremadog
Rock type: Dolerite
