Facing north west, the bay is relatively small at around 250 metres wide and is popular for swimming, surfing, sailing and windsurfing as well as beach games and sandcastle building. The picturesque village behind the beach has a shop, cafe and pub. The coastal waters and coastal belt is within the Cardigan Bay Special Area of Conservation, confirming the high conservation status of the area. The Ceredigion Coast Path links Tresaith to neighbouring Aberporth and, at low tide it is possible to walk along the foreshore all the way to the golden beaches of Penbryn, to the north. Walkers are often rewarded with sightings of seals and dolphins close to the shore. Penbryn, its sand dunes and surrounding woodland, is managed by the National Trust.
