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.

An incredible stretch of road. Very isolated. Watch out for Land Rover gangs racing up to the Florida Strata road.

At 441m, Moelfre ("The Bold / Barren Hill") is a Welsh listed Bridget. The trig point is located about 100m East, and a whole 1m lower than the actual summit. It's heather moorland (likely boggy!) terrain. Extensive views on offer in most directions, including views across the Duhonw valley to the South-East.

Wolf's Leap is a deep pool along the River Irfon. It is accessed via a small path cut into the rock. At this point the river cuts through a narrow gorge in the rock resulting in a deeper pool, perfect for a dip! Don't forgot to bring a packed lunch!

Stunning scenery, a great place to ride a bike in the summer. Can be a completely different experience in the winter though.
