Walk gw200 Moelwyn Mawr and Moelwyn Bach from Tanygrisiau

A steep ascent to fine views of two valleys

Rhosydd Quarry opened in 1840 and employed some 200 men. Since closing in 1930, the ruined buildings have become dangerous and unstable. Whilst a fascinating place to wander and imagine, best stay out of the buildings and tunnels.
