Nant Gwrtheyrn, Llyn Peninsula Walks In Gwynedd, Wales, UK
This Nant Gwrtheyrn walk was about 8 miles in distance. The terrain of this route was challenging and included field and hillside paths; short drive, track, lane and road sections; plus one very steep descent and ascent. A reasonable level of map-reading skills is desirable on this route and there are also 7 stiles to climb over.
Starting at over 300 metres altitude, this walk provides views across the Llyn Peninsula, including all its mountains and the sea to both west and east. After going around Moel Ty-gwyn, the coastal scenery dominates the view. There is also a dramatic descent to a deserted beach at Porth y Nant with its mine workings and backdrop of mountains falling straight into the sea. There is a very stiff climb past the developing Welsh Language Centre at the end of the walk which quickly regains the height lost during the walk.
Starting from the car park north of Llithfaen, leg one went south west on field paths to a road; then south east on field paths and a track to a lane. Leg two went north west by lane, tracks and field paths to a road; then south west on field paths, track and drive to a road.
Leg three went north on a track, field and hillside paths to a road; then north east on a hillside track and field paths to a track. To complete the walk the fourth and final leg went north west on track and path down to Porth y Nant beach; then north east on the beach; then north east uphill on path and road which curved south back to the car park at the start.

Nant Gwrtheyrn Route
The Nant Gwrtheyrn walk route was circular in a clockwise direction with four legs.
On this first leg we started from a car park north of Llithfaen, heading south west over field paths to a road; then turned south east on field paths and a track to a lane.
- From the car park we walked south down the lane to a waymarker post that marks the crossing of a number of tracks.
- Here we followed a bridleway marker going diagonally south west to the right towards telegraph poles.
- After passing through a metal gate we followed a path beside the field edge on the right.
- Going through a gap in the field corner we joined a path with low walls in the next field.
- Soon after going over a small footbridge, we went right through a metal gate into a large field.
- From here we kept forward towards the brow of the hill.
- Once we were on the brow of the hill we headed towards a prominent waymarker on the horizon.
- We continued forward downhill along faint track marks to pass through a metal gate in the corner.
- Here we went right on a field path beside the right-hand side wall to pass through a gate on the right into the next field.
- Here we went left a short way on a field path to pass through a gap in the wall next to a metal ladder-stile.
- In this field we followed the path, initially beside the left-hand wall.
- The path slowly veered diagonally to the right over a mound which we assume used to be a boundary wall.
- We then followed the line of another mound on our left through gorse towards the bottom right corner of the field.
- Here we went through a gate in the right side of the field onto a lane.
- We turned left here a short way to reach a road.
- Turning left along the road a short way, we then went right at a fingerpost along an enclosed track to cross a stile next to a gate and entered a field.
- From here we followed an ancient walled path on the right boundary of the field for just under a mile.
- We passed through a gap into a second field; climbed over a gate next to a broken stile into a third field; and went through a slightly obstructed kissing-gate into a fourth field.
- In this field we walked on the left side of the old road as it was overgrown and passed through an overgrown kissing-gate into a sixth field.
- Again, in this field we walked either on the left hand mound of the wall, or on the left side of the old road, as it was overgrown; and then passed through an open gate to the left of a broken kissing-gate into a seventh field.
- In this final field we walked to the left side of the old road and passed through a metal gate onto a track.
- Keeping ahead along the same line along the track we passed a farm on our right, and went through a gate to a junction with a lane.
Having walked about 2 miles to this point, the second leg headed north west by lane, tracks and field paths to a road; then turned south west on field paths, track and drive to a road.
- We turned right along the lane, bending right, then left under trees.
- At a sharp left corner, we continued ahead on a track to leave the lane through a metal gate into a field.
- Here we followed the track to the right uphill to pass through a metal gate into another field.
- Going left along the field edge we went through another metal gate into another field.
- Continuing ahead beside the left field edge we again went through a metal gate into another field just below some rocks on the hill to our right.
- Continue along the same line beside the left field edge we descended a little to reach a surfaced track.
- Here we went right along the track to pass through a metal gate next to a cattle grid to reach a road.
- We turned left along the road and on a right hand bend near a ruin we went left on a track and ahead through a gate into a field.
- Going ahead on the track across the field we went through another metal gate.
- Following the track around a left then right bend we reached a house where we ascended steps on the right and passed through a gate.
- Here we initially went left beside the fence on our left to a corner, then climbed diagonally to the right uphill through gorse.
- On the other side of the gorse in the top corner, we went up a few steps and through a kissing-gate into a field.
- Here we followed the line of left broken boundary wall uphill to stop at a wall with a gap in it, and a waymarker post to the right of it which pointed diagonally left uphill to a kissing-gate – we did not go that way.
- Here we went to the left through another gap in the wall along a path on level ground across the middle of a field.
- We crossed a gap in an old wall boundary and went straight ahead across a second field and through another gap in an old boundary wall.
- In this third field, we turned immediately right to go through a metal gate into another field.
- We crossed this field heading towards farm buildings and passed through a kissing-gate onto an enclosed path.
- We walked between walls and farm buildings and along a drive to reach a road.
At around the 3.75 miles mark, the third leg headed north on a track, field and hillside paths to a road; then north east on a hillside track and field paths to a track.
- Turning right along the road we then turned right through an open gate, along the first track at Bwlch Gwynt Bach, joining the Llyn Coastal Path towards Moel Ty-gwyn.
- Following the track left, right then left again, we went through an open metal gate just before the house and turned right and went through a small metal gate.
- We then ascended over rocky ground beside the right boundary to climb over a stile into a field.
- Going left here a short way we went through another small metal gate into a hillside field with a fenced off drop ahead of us.
- We turned right here a short way to go through a large metal gate to reach a bracken-covered hillside.
- Here we went left to skirt Moel Ty-gwyn, but navigation was a bit tricky, so we kept a keen lookout for yellow-topped posts to follow.
- After crossing a stile ahead of us we continued to skirt the hill through rocks and gently descended to a path below us.
- We followed this path around the hillside until reaching a yellow-topped post.
- From here we went diagonally left down the hillside through rock and gorse to another yellow-topped post next to a gap in a low wall.
- At the same time as aiming for a small hill below us on the coast to the right of buildings, we descended diagonally to a wall.
- On reaching the wall we went right with the wall on our left, still skirting the hill.
- At a gap in the broken down wall, we went diagonally left through it, across a field.
- Here we aimed to pass through a gap in the wall near the right corner of the field next to a yellow-topped post.
- From here we crossed a field, heading towards a road junction below us and passed through a kissing-gate and down steps to a road.
- Going straight across the road, we then went left down a slip road, to a fingerpost on our right and crossed a stile onto a track.
- Following the track, at a fork we went to the left uphill and went through a kissing gate onto a gorse covered hillside.
- We turned right here to follow the wall on our right uphill to go through a sturdy, metal kissing-gate, the first of a series of kissing-gates, and entered a field.
- Still following the right boundary, we crossed the field, going over a small boardwalk and just after a small farm building, we went through another sturdy metal kissing-gate, next to an open gate.
- Following the right boundary again we crossed another field and again we went through another sturdy metal kissing-gate, next to an open gate.
- Still following the right boundary, we crossed another field and again we went through another sturdy metal kissing-gate.
- In the next field we initially followed the mound of an old boundary wall on our right, then at a second telegraph pole with a marker, we crossed the mound and passed below the telegraph wires.
- Aiming for farm building ahead of us below the distant mountains, we crossed the field to go through another sturdy metal kissing-gate in the field corner.
- In the next field we followed the left boundary fence towards the farm buildings and went right up a few steps and through a final sturdy metal kissing-gate to the right of a gate.
- Now in another field we followed the left boundary around to the left to cross a gated ladder-stile onto a drive.
- Going right on the drive and through a gate we turned immediately left to pass through a wooden kissing-gate into a field.
- Following the left boundary of this field we crossed a stile in the corner, walked along an enclosed path and emerged on a track.
Having walked about 5.75 miles to this point, the fourth and final leg headed north west by track and path down to Porth y Nant beach; then headed north east along the beach; then headed north east uphill by path and road which curved south back to the car park at the start.
- We turned left downhill along the track and passed through a gate.
- Continuing along the track we went through a gate opening and into more open gorse covered hillside.
- After passing through a gate next to a cattle grid and where the track swung left along the cliff edge, we turned right along a narrow path.
- After crossing a small stream we forked left steeply downhill with the stream on our left.
- Near the bottom we descended rough steps and followed metal railings to the left in order to cross a footbridge over the stream.
- With a bit of scrambling and crossing two small footbridges we descended further to the boulder strewn beach.
- We turned right along the beach and did some boulder hopping.
- On reaching the pebble and gravel section of the beach we continued on until we reached to a jutting-out quarry wall.
- Here we climbed up the bank to the right and turned left along a short grassy track to reach a gravel path.
- We turned right along the path uphill and when the path changed to concrete we continued ahead.
- Near the top before a gate ahead of us, we went to the right up steps either side of a gate.
- Here we continued uphill along a Tarmac path and along a drive through the Welsh Language Centre at Nant Gwrtheyrn to join a road.
- Turning right uphill along the road, we zigzagged through woodland and had a steep, heart-pounding walk back to the car park on our right.
When Done & With Whom
I did this hike with my partner Anne whilst on a Llyn Peninsula hiking holiday in Gwynedd, Wales during April 2015. We drove from our holiday accommodation in Pwllheli, Gwynedd to a car park to the north of Llithfaen, Gwynedd marked by a “standing stone” sculpture, at grid reference SH353440, which was also the start location of the hike.
