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

This part of the trail is a little flatter than the sections before and after. It's also fairly smooth so makes for good running even when it's wet. Great views down into the valley!

Classically a route for mountain bikers, this path is perfect for gaining—or losing—some quick elevation. Passable in around 25 minutes, it's a tough climb to the top where the views are worth the effort. Just be careful for those downhill riders that can be seen flying through the trees.
