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.

Lovely mix of fire road to start with and then a huge climb up and over into a valley that time forgot - perfect single track - although can be a bit muddy in places. Probably best to make sure there has not been too much rain in the week before riding this route - and in the winter be prepared for quick changes of weather and plummeting temperatures.
