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 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.

Great selection of varied trails around the reservoir that branch off the family cycle route. Some quite challenging if it’s your first visit. The pump track and trail at the start is great to warm up and fun for the kids. Bike hire is available if needed.
