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

Hengoed Viaduct is an old railway viaduct that’s now a walkway and extension of NCN Route 47. It offers a nice view over the valley. The "Wheel o Drams" sculpture (locally known as "The Stargate") by Andy Hazell, is formed from a circle of coalmining dram trucks.
