A scalloped bay of rocky coves and white sand on Holy Island, with some of the clearest water on Anglesey — an ideal introduction to coastal paddleboarding, with endless rock-hopping for the more adventurous. It's best in light easterlies; from the main beach you can explore south towards the coves at Porth Diana. Popular on summer weekends, so come early. Parking is paid.
