Confronting the Devil's Staircase northbound from near Llyn Brianne reservoir is tackling one of Wales's most infamous climbs, famed for its savage steepness and remote beauty. Prepare for an immediate, brutal ascent as the narrow single-track road rears up, averaging a punishing 10-13% but hitting steep ramps well over 20%, reportedly reaching 25-30%. Feel the wild exposure of the Cambrian Mountains, with stunningly remote views as your reward for conquering this truly devilish challenge.

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.
