This dive site, Prego, is named after a distinctive nail-like crack found within its high rock formation off Angeiras. The site features a prominent submerged rock, with its peak rising to about 9 meters and the sandy bottom extending to a maximum depth of 19 meters. Accessible exclusively by boat, navigation primarily involves exploring the unique rock structure and its namesake crack, providing an interesting geological dive.
Divers can expect to encounter a variety of marine life, including pans, sea bream, rockfish, and sea bass. The site is particularly renowned for its abundant macro life, with various types of anemones, sponges, razors, and octopus making their home amongst the rocks and crevices.
While specific seasonal highlights are not provided, the Atlantic waters of Portugal typically offer good diving opportunities from spring to autumn. This site is excellent for macro photography enthusiasts and offers suitable conditions for both scuba divers and freedivers due to its relatively shallow average depth and interesting rock formations. Always check local weather and sea conditions before planning a dive.
