Background
Visiting
The hill is wholly within land mapped under the Countryside and Rights of Way Act 2000 as open country and hence is legally accessible to walkers despite their being no public rights of way leading to it. Mountain bikers can follow the forest roads within nearby Mynydd Du Forest, one of which tops out at 715m, just 0.5 km from the summit, but have no legal access to the hill itself.
