A lovely brewery that's worth adding on a few miles for. Check their website for taproom opening hours as they will change throughout the year

The estuary of the Afon Gwaun in Fishguard is a naturally formed old harbour. It's known as the lower town harbour and would have been the first area used commercially for fishing and trade.

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

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.
