Traversed the Goats track from below cwm Cywion, around and into Cwm Coch, up gully in Cregiau Gleision onto Y Llymllwyd, Bwlch y Cywion over to Y Garn and down NE ridge. Very cold day in the wind. Biting. Good nav practice and route finding up onto Y Llymllwyd ridge. Snow was really terrible - groupel covered by windslab - but not very deep, so able to kick through and get purchase on turf and rock below. Notch descent from Y Garn was corniced. Avoided it by heading direct down the nose of the ridge.
