Traeth Penllech (above) is a beach of sand, rocks and rock-pools almost 1 mile long, situated a mile north of Llangwnnadl on the northern tip of the Llyn Peninsula. The beach is backed by banks of boulder clay and some cliffs, with the Afon Fawr (stream) dropping down into a small gorge before emerging onto the beach. A good sized (free) parking and picnic area is at (Grid Ref SH206340), from where a footpath leads along the opposite side of the Afon Fawr to the beach. Signs warn of strong currents, so care needs to be taken if swimming here.
Porth Colmon (Grid Ref : SH195342) is a small cove on the southern headland of the bay, much used for launching of boats. The shore is mostly gravelly sand, and access is down a slipway. A small (free) parking area overlooks the beach, and would be a good spot for watching the waves on a stormy day.
