Porth Trecastell is a sandy covered beach edged by cliffs and rock pools situated south of Llanfaelog between the villages of Rhosneigr and Aberffraw on Anglesey. The beach is a popular place for fishing, surfing, swimming, canoeing and windsurfing. This narrow bay picks up plenty of swell from the south-west, but due to its size is generally best before or after high tide.The ancient burial chamber of Barclodiad y Gawres can be found on the western headland by following the Coastal Path.

Facilities at Rhosneigr or Aberffraw. Parking available. Dogs are allowed.
