Baixa das Castanhetas (Damselfish Reef)
A reef less than 500 m from the coast off the Caloura bathing area: a maze of interlinked caverns, tunnels and gorges. The first cavern starts at 12 m with three wide entrances, and the flank drops vertically to over 45 m. Clouds of Azores chromis, white trevally, cardinalfish, nudibranchs and groupers live here; schools of pelagics and occasional devil rays pass in summer. The position is approximate (the official guide publishes no coordinates) and is for orientation only.
Tiefe: 12–44 m
