Porth Neigwl beach from the dunes, with waves breaking along the shore

Surfing

The name and history of Hell's Mouth, waves at the north end of the beach, rip-current advice, and where to learn, hire and buy in Abersoch.

Porth Neigwl — Hell's Mouth — takes its name from its semicircular shape, resembling a wide, open mouth, and a savage south-westerly aspect that offers precious little shelter to sailors. The beach is roughly four miles long, lying between Mynydd Rhiw and Mynydd Cilan.

It has among the best and most consistent waves in North Wales, and surfers find consistently good waves especially at the north end of the beach. Behind the beach, grassy dunes form a notable sea-marsh, and the area is a Site of Special Scientific Interest.

The bay has a history of its own. In the days of sail the strong winds made it lethal for shipping, and over 30 vessels are known to have been wrecked there. The area at the rear of the bay was used as a bombing range and practice area for airmen, and the site was decommissioned in 1945. Offaxis — formerly A.O.A. — was started on the main beach in Abersoch in 1996, as Abersoch Ocean Adventures, offering tuition in waterskiing, wakeboarding, windsurfing and surfing.
