You step out of Croesor with peat underfoot and a slate-grey sky pressing close, the valley folding inward like a paused breath. The path climbs through scattered spoil heaps and craggy outcrops, then opens to a ridgeline where wind pushes you along—Snowdon and Cadair Idris sit as distant, familiar shapes on the horizon.
