Barmouth is a wide sandy beach backed by dunes and a promenade, on the north side of the Mawddach estuary. The main beach is subject to dog restrictions from April 1st to September 30th, and a beach supervisor is on duty during the summer. Hazards of the beach include fast currents near the estuary and sandbars. Barmouth has good facilities including plenty of P&D parking, deckchair hire, toilets, drinking water, a slipway, fairground rides and cafes. Northwards the shore is backed by shingle, and there is a further large car park at this end. Barmouth rail station is approximately 100 yards away and the town itself has more shops, cafes, hotels, supermarkets and a Tourist Information Centre. A foot / cycle path runs alongside the railway on the ½ mile long Barmouth Bridge across the Mawddach estuary.
Panoramic views of the town and estuary can be seen from the National Trust property of Dinas Olau, directly behind the town. This can be reached via Dinas Olau road which leads to a steep zig-zag path up the hill.
Surf conditions are fairly consistent, any stage of the tide is good, and it rarely gets crowded.
