Black Mountain Climb from Pont Aber

Highlight (Segment) • Climb

Although not the classic side of the Black Mountain, this is still a fantastic road to climb that crosses the spine of the mountain and immerses you in some of the best scenery Wales has to offer.

It’s a kilometre into the slope before you escape Brynamman and enter the open land but from then on it is pure bliss. After two kilometres the road bends left as it rises above the valley below on your right. Meandering across the featureless landscape, exposed to whatever mother nature has in store the majestic strip of tarmac gradually makes its way towards the summit.

With no markers on the horizon, no sharp bends or features to focus on the ascent is a test for the mind and body. Grind out whatever gear you can on the consistent 6-7% slope all the way to the exposed plateau then get ready for the exhilarating descent.

Amman Valley Cycleway

Highlight (Segment) • Trail

For families especially, but also those who prefer a more gentle ride, the route is ideal because apart from a descent near Pontamman it follows the river bank and is flat.
