Car park at Plas yn Rhiw, grid ref: SH237282


From the car park cross the road and go along the track next to the greenhouse. This track leads through to the woodland.


Go past the old millpond. Keep right at the fork and carry on along this path until you come out onto the road above the car park. The trees in this wood are about 150 years old.


Turn left along the road for about 110 yards (100m). At the sharp bend in the road, take the track leading off in front of you through the gate marked Tan y Muriau. There's a great view from here across Hell's Mouth Bay and Porth Neigwl towards Cilan in the distance.


Continue along this track, through the farmyard, and on to a way-marker to the left.


Follow the way-markers along the narrow track up to the Tan y Muriau tomb. Find a suitable vantage point to get a good view over the wall of the tomb, which is about 5,500 years old. The burial chamber is on private land, so make sure you stick to the path, or ask the permission of the landowner in the nearby Tan y Muriau house if you want a closer look.

Follow the way-marker through the field and past a small cottage. When you reach the entrance drive to the cottage, turn right onto the gravel track. Follow this track for about 270 yards (250m) until you reach a wooden gate leading up to a house. Climb over the step stile in the stone wall on your left and make your way towards the small cottage of Frondeg. This still has its original layout with a crog loft, a sleeping loft over the half of a cottage furthest from the cooking hearth.


Follow the way-marker into the forest. Look out for the cottagers' pig sty built into the slope. This is one of only three of this kind in Wales and is a listed building.

A little further along the path, before you go down the slope into the middle of the forest, look out for the old Baptist well. It's on the pilgrims' route to Bardsey Island.


Go through the gate and follow the track round to a galvanised shed, where our staff cut up felled trees. About 165 yards (150m) further on take a small path on your left, leading off the main track to the wildlife pond.

Return to the main track and walk on until you reach the road. Go straight over the crossroads and follow the old road, replaced because of erosion by the sea. When you rejoin the road, cross straight over and follow the footpath back to the Plas yn Rhiw car park, where you began.
