Which final descent though – Skyline or Whites? Both are great, but Whites is prolly my favourite overall route, especially if you mix in a loop of the black run too.
Don’t forget – there’s 2 centres that are both included as Afan. The old centre at Afan and the newer one at Glyncorrwg about 4 miles up the road. Glyncorrwg has camping, licensed cafe, good bike shop, showers, etc.
