(S) From YHA Llangattock go down to the track and turn left heading north-east towards Laswern-fawr Farm. When you reach the lane that goes to the farm turn right and head north to go past Laswern-Isaf Farm and Ty Mawr Farm and reach a minor road. Go straight ahead and climb over the wooden style to pick up the path that goes over the canal and past Park Farm. At a meeting of a path from the right, bear left then right into the tree-lined lane that goes to the A 4077 road. Turn left, past a road junction (indicating Llangattock to the left, ½ mile), keeping straight on to a turn off on the right that goes over Crickhowell Bridge. You might notice that there are more arches on one side than the other!
(1) From the bridge, head straight up New Road past St. Edmund's Church on the right and the Secondary School on the left up to the A 40 (Brecon Road). Turn left past the Porth Mawr (Gate House) and go along the road until you find a zebra crossing with belisha beacons and a path going off to the left behind a railing. This will go up to a school next to a grassy playing field. Carry on up Oakfield Drive to a pathway next to Nº 56 that will meet Cwmbeth Close. The pathway continues next to Nº 38 and meets Darren View opposite a double metal gate. The path continues straight ahead by the side of a stream (Cumbeth Brook) going uphill until you reach a sheepfold at the end of the last field. Here, the path turns right along a dry stone wall to reach Table Mountain and the Crug Hywel.
(2) After exploring the fort and enjoying the views back to Crickhowell and the River Usk, the route heads north-east, descending gradually down to Graig-Iwyd Farm and the local road at Green Cottage. Turn left and the right through a metal gate opposite Ffawydd Farm (the furthest gate of two). The path heads east then zig-zags through the wood to go south through Llwynon Farm and join the local road a bit lower down through a metal gate (follow the path from the farm, not the entrance road). Go down the road until you find a driveway leading off to the left to Draen Farm. At the back of the farm, the path goes up to another track. Turn right then sharp left to climb be the side of a dry stone wall to open moorland, heading north-east. The path bends right to head west along the edge of the fields and eventually bears left away from the fields to climb up Crug Mawr.
(3) From the trig point, head east-north-east to gradually descend to a sheepfold and a track. At a crossroads bear right towards Ffynnon Tshow and Nant Mair. Ignore the path going off to the left via a wooden style and signpost near some farm buildings. The road bends right then left then right again to reach the entrance to the Partrishow Church St Issui's (Ty'n-y-llwyn) on St. Thomas's Way. After exploring this particular historical gem, pick up the path heading north-east past Ty'n-y-pant farm and down to the road over a wooden style. Go straight across the road and down to the Tabernacle Baptist Chapel Cwmyoy, crossing the Grwyne Fawr. Ignore the road leading off to the right by the river and head straight past the chapel. The road bends left, and eventually reaches Ty-mawr Farm and continues, heading roughly north as far as Upper House. The track bear right along the dry stone wall to reach another path at Coed Mawr. Bear left to pass Coed Ty-canol wood on the right and reach open moorland to climb steadily to a cairn at Garn Wen.
(4) From the cairn, head north then bear north-north-west to reach a pile of stones on Bâl Bach (520m). From here, turn north-north-east to go down the side of Cwm Bwchel stream to a farm of the same name. Carry on along the stream to reach Afon Honddu river. The route crosses the river over a footbridge and goes through some farm buildings to reach the road near a telephone box. Go across the road to Llantony Priory.(E)
