Hiking in the Brecon Beacons - Brecon Beacons National Park Hiking Guide with Pictures and Maps. Offering the highest peaks in South Wales, many dramatic views over the glacial scenery and an intereting variety of trails, the Brecon Beacons are a hiker's playground.
Hiking trails criss-cross the national park allowing the creation of custom routes.
The most popular route is actually one of the least attractive. It starts from Storey Arms on the A470 and climbs Y Gryn and Corn Du on the way. If you keep a steady pace a round-trip can be completed in under two hours. Descend either by following the ridge of Cefn Cwn Llwch and return to the start along the pretty lanes around the base of the mountain or back across the peaks and along the quieter footpath skirting the ridge of Pen Milan, through a few sheep fields and back to the car park. Trace the road back to the telephone box and walk the path across to the trail running parallel to the river Nedd Fechan.
