1. With your back to the car park, head up the footpath in the woods opposite. Remain on this well-trodden path as it snakes through the trees (watch out for speeding cyclists when crossing the cyclepath). You will eventually come out at a yellow marker; turn right continuing up on main path, then right onto ‘no bike trail’ behind staggered fence/bike-proof gateway. Follow this for around 500-600m until it opens out to magnificent views across the hills. Turn around and trace the route back, to main path then turn right. Take a right onto a small path into the woods, then light again, back onto main path. Head to Penrhos Isaf Bothy (looks like a cottage in the woods) on left.
2. From the bothy, head past the adjacent ruined building and take the left-hand fork. After crossing main path, you come to a section which is shared with cyclists (be very careful here). Take right when it forks to join main path to left. Then to forestry gate and viewpoint.
3. Carry on straight over onto bridleway. Cross brook, leading onto wider path. Through a gate, continue in same direction on lane until you reach a bridleway directing you up and to the right alongside a drystone wall. Left at bridleway marker, over bridge. Take a right, then left to continue in the same direction. Come out to larger track to message board by a rocky cliff.
4. Carry on this large track until you reach a steep climb ahead of you. Don't take this steep path, instead take the (no bike) footpath behind you. Walk down the path to main track. In the summer - or for brave winter swimmers - there is a wild swimming spot to the left, close to a footbridge.
5. Continue southwards on this main path - you'll see the winding river below to your right and pass another footbridge. This is all mostly on the flat. There are mountain bikers but they are mainly slow as this marks the end of several rides. Amble along this section of path back towards the car park.
