Cricieth has two beaches, separated by the castle. Cricieth East Beach is the western extremity of Black Rock Sands and you can walk over this far at low tide. The top of the beach is mainly pebbles but there is sand at low tide. Cricieth West Beach is backed by a mainly residential promenade, whilst Cricieth's High Street and shops are not far away. The top part of the beach here has the most sand with lots of large rocks exposed at low tide.
