A great place to view western Pembrokeshire. The bridleway descent to the north west is very overgrown though.

Foel Cwmcerwyn is the highest point of the Preseli Hills at 1,759 feet (536m). It also marks Pembrokeshire's County Top and is a UK Marilyn so you can tick it off a few lists if you're hill bagging. From the north, it's an unassuming and fairly gentle (if rather boggy) approach. The south face footpath is a little steeper, with better panoramic views.

Slate was quarried in a small way at Bellstone Quarry from the 1820s, while the now flooded Rosebush Quarry was opened in 1842. At the peak of the boom years the quarries employed 100 men. Nowadays you will find some nice trails to walk among the heaps of slate, and a cool (or perhaps, cold) wild swimming spot.

Because Foel Eryr summit is so easily reached from the nearby Bwlch-gwynt car park to the east, allowing nearly all of the climbing to be done in the car, it's easy to lose the true sense of the scale of the hill and its place in the landscape. Plan a circular walk to really appreciate a Preseli gem. That said if time is short, the reward for a 15 minute walk can be some outstanding views - on the best days you will be able to spot Lundy to the South, Ireland to the West, Snowdonia to the North and Brecon Beacons to the East.

This is a UK listed Marilyn so worth doing. Great views from here on a normal day but not on the day I have done it. The Preseli mountain range is a hidden gem in Wales so don't go about telling everybody about them :-).
