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.

The views from Foel Feddau summit, at 1,432 feet (467m), make the slight detour from the Golden Road, the ridgeline that forms the spine of the Preseli Hills, worthwhile. The views of the steeper east face of Foel Cwmcerwyn are particularly good.

The beautiful Gwaun Valley runs from Lower Town Fishguard towards The Preseli Mountains. It's a peaceful, steep-sided valley and is part of the Pembrokeshire Coast National Park. It has a unique "lost-in-time" kind of atmosphere and an abundance of wildlife and prehistoric sites.

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.
