A wonderfully wild bridleway that runs along the summit ridge of the Preseli hills. Best ridden from west to east so that it's predominantly downhill and much better in dry weather, it gets a bit boggy in the winter.

At the end of the road you will find Cwm-yr-Eglwys, a sandy cove with a stream running through the middle, popular with boat users. Above the beach is the end wall of a chapel. The rest was washed away in the enormous storm of 1859. There is a 10ft high wall surrounding the top of the beach, making it very sheltered.
