A lovely little tucked away quarry which is great to have a dip mid run. The water is freezing though so bare that in mind! Great area for running and exploring the Presellis

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

Lovely views along Preselis

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.
