Aberdaron Beach is about 1¼ miles long, mostly sandy and backed by banks of sand and boulder clay with a concrete sea wall protecting the village. The sand is fairly course at the top of the beach, becoming finer lower down. It's good for pebble collecting, with an amazing variety of assorted pebbles to be found, including white quartz, purple sandstones, grey-green diorite and black siltstone. The beach looks out towards the islands of Ynys Gwylan to the south. Parking is at an attended / P&D car park in the village, and facilities include toilets, cycle parking, picnic tables overlooking the beach, First Aid post (seasonal), ice-cream and beach shops, two pubs, a fish & chip shop and a Spar store. There is also some free parking space at the top of the hill leading west out of the village, from where access to the beach is a walk down a track leading to a slipway onto the sand.
It's a popular beach for windsurfing, swimming, kayaking and surfing. The surf here can be a bit messy and there are some lone rocks on the beach to be aware of, but mid to high tide is the best time to aim for. Boat trips run to Bardsey Island during the summer months, departing from nearby Porth Meudwy. A dog ban operates on about 150 yards of the beach in front of the village, from 1st April to 30th September.
