A sandy but exposed beach with easy access and parking (15 minute drive from Parc-Le-Breos B&B). The beach can be quite busy in summer months on account of the many campsites nearby. At the head of the beach are a number of beach shops, cafes, fish and chip shops and a pub. On the west side of the bay are the ruins of the salt house where sea water was boiled to leave salt which was then used in the preservation of the fish. It is likely that Port Eynon was chosen as a location for the salt house not only because of the fishing industry which was once based here, but also because the bay has a relatively high salinity, being quite shallow with the absence of any rivers flowing in. If you venture to the end of Port Eynon Point at low tide, you may catch a glimpse of the boilers of the Agness Jack - one of the many wrecks at the end of this treacherous headland. Walking further west (just around the corner of the point) you will come across Culver Hole, a mysterious walled up cave entrance thought to have once been used as a dovecote to aid winter food supplies.
Boat launching is to the west of the beach (be careful of the deep sand at the end of the slipway) and there is a boating lane demarked by yellow buoys. The beach is good for water sports, being lifeguarded and having easy launching for sailing dinghies etc. Gower Coast Adventures operate their boat trips and booking office (a sign-written minibus) from here in the summer months, running excursions all the way to Worms Head, and Mumbles in the other direction. Three or four wrecks lie out in the bay and on the point, which makes the area a magnet for divers when the water visibility is good.
The beach at Port Eynon is OK for flatfish, and sometimes bass on a rising tide, but you're better off heading to the steeper more turbulent Horton end of the beach. If its bass you are after, you should head out along the point on the west which is actually one of the better places on the peninsula to fish. I have had good luck here using peeler crab set about 20 inches above the weight to get clear of the rocks. Also try spinning for mackerel and pollock at full tide.
Port Eynon is generally too sheltered to have any surf except in extreme swells, but see the description of Horton (the other end of the bay) which can be quite good.
