Great view over Garreg Ddu Dam (not Craig Goch Dam!) after a steep but worthwhile climb

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.
