Where it is
The circle shows the general area, not the exact start. Use the directions link below to get to the car park itself. Contours and paths shown are OpenTopoMap, drawn from OpenStreetMap data.
The route
Colour-coded trails of varying length climb from the visitor centre through the forest to viewpoints over the reservoir and the Taf Fawr valley.
Worth knowing
- Sheltered and well surfaced, which makes it a reliable wet weather option under the Bannau.
- The centre has a café and play areas, so it is popular with families.
- The longer trails climb high enough for a proper view of Pen y Fan.
What you’ll see
Conifer forest, small waterfalls, and the reservoir with the Bannau beyond.
Background
