Local rules, hazards & spot guide

Need to know

The things that catch people out here.

  • It is called Hell's Mouth for a reason. Powerful rips, heavy shore break and a bay that has claimed a great many ships.
  • Access points are limited and there are no facilities. If something goes wrong you are a long way from help.
  • This is an experienced riders' spot when the forecast is powerful. Abersoch on the other side of the peninsula is the sane alternative.

The spot

Porth Neigwl — Hell's Mouth — is a four-mile bay on the exposed south-western side of the Llŷn, facing straight into the prevailing swell. It is one of the best wave spots in Wales and one of the least forgiving.

Rips run the length of the bay, the beach break is heavy on a solid swell, and access points are few with no facilities and patchy phone signal. The name comes from the number of sailing ships that were embayed here and wrecked. It is a spot for people who are confident in serious water, and Abersoch, ten minutes over the neck of the peninsula, is the alternative on the days it is not.
