The Beacons circuit - directions

Way to go

Set off from the car park opposite Storey Arms Outdoor Education Centre. Cross the A470 and head for the gate and stile to the left of the centre. Ignore the stone path and take the less obvious track off to the left (it’s the right of way marked on the OS map). After about 250m cross the remains of an old stone wall and continue on up.
At the top of Y Gyrn (619m) cross the stile over the fence and stop to admire the superb view of Corn Du (ahead) and Pen-y-Fan (left). The track here becomes harder to see. Follow it down a gentle slope before curling up and around to walk along Craig Cwm Llwch ridge, passing Tommy Jones’s obelisk on the way. Watch out for unexpected gusts of wind along these exposed edges.
Continue to the summit of Corn Du (873m) then bear north-east, dropping down into a saddle and back up to Pen-y-Fan (886m). Soak up the panoramic views before leaving the summit in a south-easterly direction down Craig Cwm Sere before climbing up to the top of Cribyn (795m). Follow the gentle decline off Cribyn along Craig Cwm Cynwyn to meet the wide, stony track at Bwlch ar y Fan, otherwise known as ‘The Gap’.
Turn right and follow the track downward for about 1¼ miles (2km) towards the Neuadd reservoirs. Above the deep cutting in the track opposite the lower reservoir turn right and go through a metal field gate into the reservoir complex. Bear right here, continuing along the track; when you reach the Tarmac road turn left down the hill towards the old filter house. Cross the Lower Neuadd reservoir’s dam wall and go through a metal field gate back onto the open hill.
Climb for 200m alongside forestry in the direction of a trig point at 642m – it’s a steep and often muddy path. Once at the top turn right and walk along the length of the ridge. At Bwlch Duwynt, a junction of the paths below Corn Du, turn left down towards the forestry at Pont yr Daf. At the bottom cross the bridge over the Taff Fawr and once in the car park turn right and walk along the road back to Storey Arms.
