Personally, I think this is harder than the Bealach - it's just unremitting all the way up - you can do a wonderful circuit as a reward when you get to the top... read more

The road surface is very good all things considered. One of Gwynedd’s toughest and best challenges. Wasn’t busy.

Like a fish out of water. Truly gasping but no dabbing and a valuable insight into my level of non fitness. Nice views and descent.

A must-do climb, if only to prove to yourself how far you can push without putting a foot down.

Very few climbs in the UK can sport such severe, continuous gradient as this; thankfully the road surface is decent and although really narrow, it's a great climb... the views! the Views! Insanely good and dramatic.

Can't believe this has no reviews yet. A long, tough challenge, scaling the side of a dramatic scree-strewn valley. The tight righthand corner near the bottom is probably 33％ on the apex of the bend, but since we ride on the left in UK it's more like only 20％ you need to tackle. Very quiet road, well-surfaced. A few sheep for company. Valley is angled to catch and funnel the prevailing wind, which can be helpful when going up.
