This is a strenuous walk with spectacular views of Talybont Reservoir and the Brecon Beacons.

Initially, the route climbs gently through fields to a high point and then descends to the reservoir dam.  There is then quite a stretch of walking on the flat over the dam and down the east side of the reservoir.  Then the route climbs on a quite rocky and uneven stretch to a part of the Taff Trail, where there will be the opportunity to take a quick break and get a first glimpse of the reservoir below.  From here, the route climbs again to a ridge, on a quite steep and rocky path, with possible wet stretches, but also with intervals of more gradual incline, allowing a pause to catch a breath.  There are some lovely views on this stretch and the path eventually crosses the Bryn Oer Tramway and links up with the Beacons Way.  Weather permitting, we will stop for lunch at the top and enjoy the views across the hills and down into the valley.

The descent is more gradual with more views of the reservoir. The route crosses over the Taff Trail again before going through a forest and coming out onto the floor of the valley, and then crosses the Caerfanell river via a wooden footbridge.  The path then continues down a lane and turns onto a short stretch of road, before taking another steepish climb to a track through the forest on a good, level surface, for about two miles, back to the parking area.
