Site details

Carl's Hill, on the northwest of Klein Bonaire, is a celebrated boat dive named for underwater photographer Carl Roessler, featuring shallow coral gardens that fall away to a vertical wall around 40m. The drop-off is densely covered in tube sponges, gorgonians and corals, making it one of the island's richest sites for both wide-angle and macro photography. Seahorses, frogfish, turtles and morays are regular finds.
