Between the headlands of Penrhyn Nefyn (to the west) and Penrhyn Bodeilias is a 1½ mile long sheltered sandy bay. The section of the beach below Nefyn village is known as Porth Nefyn and the extreme eastern end as Porth Bodeilias. Porth Nefyn is mostly sand with a small harbour and beach huts. Swimming is generally safe, and the high cliffs provide shelter for sunbathing.
Porth Bodeilias is a mix of coarse sand and shingle backed by steep boulder clay slopes. This part of the beach is much quieter.
A steep lane (Lon y Traeth) leads from Nefyn village to a (free) parking area with space for about 20 cars overlooking the beach. Toilets ♿ are located halfway down the hill and final access to the shore is down a slipway. The high peaks of Yr Eifl mountains dominate the skyline to the north-east. Dog restrictions apply west of the car park from April 1st to September 30th and a Beach Warden is on duty during the summer. The photos of Porth Nefyn were taken at high tide.
