Penllech Beach (Traeth Penllech)

Penllech Beach - Gwynedd

Set towards the northern tip the beautiful and remote Llyn Peninsula is Traeth Penllech beach. This sandy beach stretches for over a mile long at low tide. To either end are rockpools whilst to the back are sloping, grass covered cliffs with some interesting rock formations.

About halfway along the beach is small waterfall where the stream of the Afon Fawr has cut a gorge into the cliffs behind.

Just around the western end of the beach is a small cove (Porth Colmon) where there is a slipway and little car park above.

I’ve had conflicting reports of whether it is safe to swim at Penllech. However, there are signs warning of strong currents, so given the lack of lifeguard cover I’d advise against it.
There can be good surf at Penllech on the right conditions.
