Hiking
In the heart of the secluded Nantlle Valley, Dorothea Quarry's slate veined pits and deep, dark pools silently remind all who wander by of the region's mining heritage. Six pits remain, the deepest dropping 348 feet (106 m) below the surface. Quarrying ended here in 1970.
The pits constantly needed pumping in order for them to stay dry. In 1904, a Cornish beam engine was installed, which today is a Grade I-listed building. Its operation ceased in 1951, when it was replaced by electrical pumps.
