This walk from the hamlet of Rhiw in the Ll&ycirc:n Peninsula follows a quiet lane down to join the Wales Coast Path at Penarfynydd. The farmland in this area is characterised by small fields enclosed in stone walls. From Penarfynydd there is an option to extend the walk to the small cove at Ysgo. The main route then heads east to climb to the summit of Mynydd Penarfynydd for extensive view along the coast extending from Bardsey Island to Hell's Mouth.

There is limited on-street parking in Rhiw (grid ref. SH226278) at the road junction on the south side of the hamlet. After parking take the lane south, signed as a no through road. Continue down the lane taking the right fork after 400 metres. Continue down the lane enjoying excellent views west which include Mynydd Mawr, Mynydd Anelog, Bardsey and Aberdaron. At the end of the lane you reach Penarfynydd Farm (grid ref. SH219267) where you have the option of extending the walk to visit the picturesque cove of Porth Ysgo. This option adds an extra 1.7 miles (2.7 kilometres) and 300 feet (90 metres) of ascent to the walk.

If you have opted not to visit Porth Ysgo, turn left through the farmyard along the Wales Coast Path. Pass through the gate to the left of the farmhouse and bear right to join a path with the wall on your right. The path soon trends away from wall and leads onto the headland of Mynydd Penarfynydd. The view from the headland is extensive including the mountains of Snowdonia and St. David's Head in Pembrokeshire. To continue the walk, double back and fork right following a path up the crest of the broad ridge. This leads to the OS trig point (177 metres).

From the summit, walk half left following path in an easterly direction to a gate. Continue to the corner of the field and join a track (grid ref. SH223267). Continue past a small sewage plant on your right. Continue along the track through a gate. Soon some cottages come into view ahead. Turn right through a gate past a rocky outcrop on your left. The path trends to the left with a great view along Hell's Mouth. Follow the undulating path ahead across the hillside. As you progress you pass small fields enclosed with stone walls. After passing a solitary cottage on your left, the path forks by a stone wall. Bear left here and follow the wall on your right. After passing a cottage on the right, the route bear left to follow a track to pass another cottage on the left. Continue past a larger house on the left. Before the next cottage, turn left and follow the path with a wall on the right. Cross the steps and turn right with a house on your right and follow the access drive to reach a lane. Turn right back to the start.

Optional extension to Porth Ysgo - from Penarfynydd Farm pass through the gate ahead and turn right immediately through another gate to follow the Wales Coast path in a westerly direction. Follow the fence on your right through fields to join a lane (grid ref. SH216269). Turn left along the lane and continue around a sharp right-hand bend. About 60 metres beyond the bends turn left onto a signed footpath turn sharp left to continue along the Wales Coast Path. The path continues down the quiet valley of Nant y Gadwen. At the bottom of the valley bear right through a kissing gate to reach the cliff top above Porth Ysgo. Follow the path down steps to reach the beach. Retrace your route back to the Penarfynydd Farm and turn right through the farmyard. Continue with route in paragraph three.
