Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

This area is also great for some technical trail running. Plenty of footpaths meander around the hills.

Very helpful staff who kindly refilled our water bottles - also pointed out that on entering the main carpark there is a public tap next to the unit/toilets on the left.

July 18, 2022, Hengoed Viaduct

The coal mining industry transformed the landscape of South Wales and one of the ways it did that was bringing about the construction of railways and, to span valleys, their accompanying viaducts. Hengoed's viaduct is vast and incredibly impressive. Thankfully, after 35 years of being completely closed, it's now a foot and cycle path, and part of the National Cycle Route 47.
