Devil's Staircase Climb (Abergwesyn)

Highlight (Segment) • Trail

Deep in the wilderness lies a hill that needs no introduction, the Devil’s Staircase, and it’s the opportunity to tackle this beast that will lure many to sign up for the 300km of the Dragon Devil. Be warned though, this road can devour the freshest of legs, never mind those with 190 kilometres of riding in them.

Leaving Abergwesyn, rising gently through the isolation you reach a couple of bridges in the rocky valley then ahead the road disappears into the trees past a weathered sign warning of the upcoming perils.

Straight away the narrow surface pitches up to 25% as you grind your way into the eerie conifers to reach a left hand bend. The road levels a little here, allowing you to catch your breath, but then it’s straight into the next incredibly tough stretch, which ends with a sharp almost unrideable 30% right-hand bend.

After this it backs off a bit, but there’s still a good distance of very tough climbing before you can finally relax.

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