An awesome road climb up the side of a hill to the top of the damn, where you can ride along the top on the road. Leads onto a gravel path suitable for gravel/MTB bikes

The Claerwen dam took 6 years ti complete and was finished in 1952. It was given a late Victorian finsh so that it blended in with the earlier dams in the valley. It's a big one - almost twice the size of the other dams in the Elan valley and the Claerwen reservoir is almost the size of all the other reservoirs in the Elan Valley system combined.
