Porth Neigwl | Hell's Mouth

Llanengan, Gwynedd, LL53 7LG

This beach’s dramatic English name is based not just on its semicircular shape resembling a wide, open mouth. Its hellish dimension comes from a savage, south-westerly aspect that offers precious little shelter to sailors. Surfers, on the other hand, treat it as a Nirvana of consistently good waves, especially at the north end of the beach. Swimmers should beware of the strong currents and undertows. Care should also be taken on the soft cliff tops of boulder clay, remnants from the last Ice Age (walkers are advised to keep away from the cliff edge and from the base of the cliff due to regular landslips). The beach of golden sand with a scattering of pebbles extends for about four miles.
