Two areas of bouldering: Craig Cywarch and Bwlch Our Drws.
Cywarch: despite the huge walls in the valley there is not a lot of bouldering. The best rock lie by the stream running down the valley past the mountain hut.
The pass that runs from Dolgellau to Dinas Mawddy has some walls and boulders on its western slopes, clearly visible from the parking at the top of the pass.
