A short climb up from the road brings you to the Dam and carpark, there is no access over the Dam itself. But you do get a good view over the spillway and valley below.

Elan Valley is a mountain bikers dream. A mix of natural trails that follow the reservoirs and crest the lofty tops of each valley. There's also a great trailhead in the middle of the valley at Nantgwyllt for some great flowing singletrack.

Went rear brake only down the steepest part (slate section near the end) just to stop the fear of front end washing out.

The old church, along with the manor house and nearby cottages, were enveloped by the waters and lost forever when Caban Coch dam was built. Among the lost houses was Cwm Elan, once the home of poet Percy Bysshe Shelley's uncle. Shelley visited on several occasions and fell in love with the area. In 1812 he tried to buy Nantgwyllt House, as a home to settle into with his wife Harriet. The old church at Nantgwyllt may have been lost, but in 1898 a new church was begun on high ground overlooking the Garreg-ddu viaduct. The architect was Stephen W Williams, who also built Elan Village to house workmen labouring to build the dams. The new church was erected at the southern end of the viaduct.
