The Gulf of Papagayo divides neatly between Playas del Coco, which holds the bulk of the sites and suits divers from beginner level upward, and the Bat Islands, a smaller cluster where strong currents attract advanced divers. Reef and pinnacle sites dominate, with muck diving, wrecks, walls and artificial structures also represented. The Guineafowl Puffer and White-spotted Puffer are seen across almost every site, while the Whitetip Reef Shark, Spotted Eagle Ray, Cortez Angelfish and King Angelfish are consistent presences. Visibility varies considerably by season.

Playas del Coco is the larger sub-area and offers the widest variety of site types, including reef, muck, wreck, pinnacle and artificial structures, across a broad range of skill levels. The Bat Islands is a smaller cluster focused on more advanced diving, with consistent strong currents at sites like Bajo Negro. Both sub-areas are accessed by boat.
