About Abereiddi to Abermawr
Popular with divers and coasteerers, Abereiddi's Blue Lagoon is a spectacular coastal feature. The lagoon is actually a flooded former slate quarry and you can still see atmospheric ruined quarry buildings on the clifftops. Escape from the hustle and bustle of modern day life with a walk along the quiet and secluded Abermawr Beach, with marsh and woodlands behind. It was once selected by Brunel as a cable and railway terminus. Then explore Abercastle, a picturesque cove and fishing village, with a sand and shingle beach. Ruined limekilns and a corn store are further signs of Pembrokeshire's industrial past. This is a great coast to explore by kayak. Whether you’re spotting seabirds on the rocks or just towing a mackerel line, you can often see more from sea level than from the coast path - and with half the effort.
