April 13, 2025, Rhigos Climb from Treherbert

Climbing the Rhigos northwards from Treherbert is a classic, sustained South Wales Valleys ascent featuring scenic hairpin bends and panoramic views. Settle into an endurance rhythm for the long climb averaging around 5%, but be prepared for steeper ramps hitting 10-15%, particularly on the iconic hairpin section midway up. Experience the dramatic scenery as you rise above the Rhondda valley onto the open moorland. The road surface is generally good following major repairs completed in late 2024, allowing you to focus on conquering this rewarding climb.

An epic ride to climb one of the most scenic vistas in the Southeast Valleys of Wales. ... This route is brutal. It's long. It's hard. It can break your soul.

Think this is my favourite way up the Bwlch. There's pretty much always a view. Road surface is good. Drivers give space. Sheep tend to stay out of the road. One of the climbs that helped me make choice to move back to the valleys to have on my doorstep. Didn't get to on the 2020 Dragon Ride, as would've need lights by the time I got there, that I'd charged, then forgot to put on the bike :-( 2022, it's going to go better :-D

Really nice gentle climb up from nelson. Road surface is relatively good. However be cautious on the decent for vehicles coming in the opposite direction, the road is very narrow in parts, with a couple of blind corners.

Best side of the Bwlch to climb from, sharp kick to start up to the houses, then a bit of flat before the climb proper starts.
