Glynneath Hill Climb

Highlight (Segment) • Climb

This climb appears minor in the grand scheme of things, but underestimate it at your peril.

Once you’ve negotiated the junctions in Glynneath the road bends right then rears up to disappear into the cover of trees where, with the last house behind you the reasonably busy road, lined with thick foliage either side, settles into its solid 6% gradient.

Heading in a direct straight line there’s no let up in the degree of the slope, nor in the amount of trees that obscure the view you are working so hard to enjoy. At roughly half distance there’s a left hand kink in the road and you enter the next long straight that will take you to the summit.

Ahead almost the entirety of the remainder of the climb is in view which gives you an idea of the work needed but could also be a hefty psychological blow.

Rhigos Climb Viewpoint

Highlight (Segment) • Viewpoint

This is the ‘classic’ way to climb Rhigos, riding north to south as it treats you to two fantastic hairpin bends that could have been plucked direct from the Alps.

It’s a solid climb although never too steep which starts in a dead straight line before bending left past the old Tower Colliery. The gradient increases as you enter the second long straight, after which the road twists right into a conifer plantation.

Ahead you’ll see the first of the two giant bends and if you look left you’ll spy the road climbing above you. As you head into a smooth, tight bend and swing back round, the slope increases slightly and the views out over the valley open up.

Easing slightly before the next turn but climbing steeper out of it, the pitch now ramps hard up the side of the mountain with a barrier on the left and a sheer rock face to the right. Sweeping round you now just have to push yourself on to finish over the brow past the car park on your right.

Bwlch Mountain Climb from Treorchy

Highlight (Segment) • Viewpoint

Climbing the Bwlch Mountain southwards from Treorchy (A4061) is a classic South Wales Valleys experience, offering a long, steady ascent. The road winds up from the Rhondda valley onto open moorland where the main challenge often becomes the significant exposure to wind. Enjoy the sweeping panoramic views from the top of this popular and rewarding climb.
