About Tremadog (Craig Bwlch y Moch)

Famous 'rain-shadow' crag — often dry when the rest of Snowdonia is wet. Golden dolerite, south-facing, low altitude, quick drying. Owned by the BMC. Trad classics from Christmas Curry (S) through Vector (E2) to Strawberries (E7). Multi-pitch up to 76m. The rock is fine-grained, highly featured dolerite offering steep crack jamming, sharp flakes, and exposed corner grooves — sheltered from cold north winds by the woodland setting. Other Tremadog classics include One Step for Mankind (VS 4c), Merlin (E1 5b), Vulcan (E2 5c) and Scratch (HVS 5a). Approach is a short five to ten minute woodland walk from roadside parking laybys near the Eric Jones cafe. Peregrine nesting closures apply on upper walls from March to end of June — check local notices before racking up.
