Arcos da Caloura
A sheltered bay about 300 m off Caloura. The reef top is at 5 m, and the main attraction is a cave with four entrances at about 16 m, whose ceiling is often covered in nudibranchs; big white trevallies and dusky groupers are regularly seen inside. Moray, Guinean puffer, rainbow wrasse and flounder complete the picture. The position is approximate (the official guide publishes no coordinates) and is for orientation only.
depth: 5–20 m
