Porth yr Afon (above) and Porth Isallt-bach are the first two of a series of small sheltered coves north-west of Trearddur Bay. The shore is of sand and shingle, backed by a sea wall and flanked by mica-schist rocks. The road (Lon Isallt) runs just behind them. Parking and facilities are available just a short walk away at nearby Trearddur Bay.
