    Calabas Reef on Klein Bonaire is a site we always make time for. Drift diving here is the norm, and it’s a gentle ride along a wall that really delivers. We love the feeling of just gliding, letting the current do the work as the reef unfolds. Keep an eye out for the Ivory Cerith snails, they’re everywhere, slowly inching along the substrate. The parrotfish population is healthy, you’ll hear them crunching away, and the Grooved Brain coral formations are particularly impressive here, some of the largest we’ve seen. Look closely in the nooks and crannies for Dusky Blennies, they have so much personality. We’ve had great luck spotting Coney and Hind tucked into the reef, and the Greater Soapfish are often out and about, a real treat to watch them hunting. The reef here is solid, a real classic Bonaire wall dive, and it’s a good option if you want a relaxed dive with consistent reef life. It's suitable for most divers who are comfortable with a drift, and it's particularly good for photographers looking for macro subjects like the blennies, or wide shots of those huge brain corals. Early morning often gives the best light and fewer boats.
