Porth Ceiriad is at the tip of the Llyn Peninsula, between Abersoch and Hell's Mouth. Porth Ceiriad gets a good deal of swell from the south west which makes it ideal for surfers, especially at the eastern end of the beach, where waves refract off the cliffs forming powerful "pyramidal" waves. First timers may want to start further along the beach. The car park is on the cliffs above the beach and accessible via Nant-y-Big farm.....
