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.

A big, but very beautiful push/ride/singletrack that climbs up the valley. Rideable in places but steep and rocky in others. Really lovely scenery but needs a bit of shoving to get a bike up it.
