Fairbourne Beach is a sandy beach on the south side of the Mawddach estuary opposite Barmouth. Longshore drift has created a spit which extends into the estuary, giving the beach a total length of about 2 miles. The southern half of the beach is backed by a pebble bank, and the northern half by low dunes. Swimming is generally safe at the centre of the beach, but rip currents will occur near the Mawddach, and also in surf conditions. Car parks are located at the centre of the beach and at either end. Stations for the Cambrian Coast line and the narrow (12¼ inch) gauge Fairbourne Railway are located approximately ½ mile away along the appropriately named Beach Road. The Fairbourne Railway runs to the northern end of the beach, usually connecting with a passenger ferry to Barmouth.
Swimming is generally safe at the southern end, away from the estuary. Toilets and drinking water are available, and dog restrictions apply to the southern half of the beach from 1st April to 30th September.
Morfa Mawddach beach is a wide expanse of soft sand between Fairbourne Beach and Barmouth Bridge. It lies on the southern side of the Mawddach and can be reached by following the foot / cycle path from Morfa Mawddach station towards the bridge. Just before the bridge, a stile on the right leads onto the shore.
Morfa Mawdach station (on the Cambrian Coast line) has a good-size car park and toilets, and was once a junction of two branches - the other branch (closed in 1965) running to Dolgellau and Ruabon. Its route as far as Dolgellau is now a popular 7-mile long cycle path known as the Mawddach Trail.
On the hills to the south is a flooded slate quarry known as the Blue Lake, which is a popular swimming spot and can be reached via a short tunnel.
