This dive site, Chapeirao Atlantida, is a spectacular and little-visited spot within the renowned Abrolhos region of Brazil. It features impressive underwater formations, locally known as "chapeirões," that create an intricate network of passages and channels for divers to explore. The highlight is a spacious underwater "lounge" capable of accommodating nearly 15 divers, offering a unique geological experience. There is no specific historical background provided for the site itself.
The marine life here is abundant and diverse, with vibrant corals, various algae, and numerous sponges covering the formations. Divers can expect common encounters with a rich array of reef fish, large schools of fish, graceful rays, majestic turtles, and significant specimens of grouper, as well as whiting.
While no specific best time to visit is mentioned, the Abrolhos region is generally best explored during the drier season (typically May to September) for optimal visibility and calmer seas. Divers should possess good buoyancy control to navigate the passages and appreciate the detailed topography. The varying depths from 8 to 32 meters make it suitable for both experienced freedivers exploring shallower reefs and scuba divers delving into the deeper channels and the lounge.
