Costão da Jaconema - Deck Pous Nautilus (Ilha Grd RJ)

This dive site, Costão da Jaconema - Deck Pous Nautilus, is located off the coast of Ilha Grande in Rio de Janeiro, Brazil. It's characterized by a classic rocky coastline with relatively shallow depths, making it accessible to divers of all skill levels. The dive site is easily accessible by boat from the Nautilus Inn, offering a convenient starting point for exploration. The underwater terrain consists primarily of rocky formations and reefs, providing a diverse habitat for marine life. The diverse ecosystem supports a rich variety of marine animals and plants. Divers can expect to encounter coiós (possibly a local fish name), friars (likely referring to a type of fish), octopuses, squids, rays, and turtles. The abundance of marine life contributes to the overall appeal of the site. Various types of algae and invertebrate life contribute to the biodiversity of the underwater landscape. Night dives are particularly recommended at this location, promising enhanced encounters with nocturnal marine species. The best time to visit is likely during the warmer months (October to May), when visibility is generally better and the water is warmer. For freedivers, the relatively shallow depths and generally calm conditions make this an excellent location for shallower breath-hold dives. Divers should be aware of potential variations in current strength and maintain appropriate safety precautions.
