Why dive here
With 192+ marine species recorded in the area - including barracuda, blue sharks, orcas, sea turtles and sperm whales - Sebastian Reef offers some of Klein Bonaire's richest reef diving. Water ranges 27-30°C, warmest September, October, November.
Sebastian Reef is one of those Bonaire sites that often gets overlooked for its flashy neighbours, but we think that’s a mistake. While it shares a name with the nearby restaurant, the dive itself is surprisingly tranquil, especially if you hit it early. The reef starts as a gentle slope, maybe 5-6 metres deep, before giving way to a proper wall that drops to about 16 metres. We love how that deeper section is absolutely covered in massive boulder brain corals and blushing star corals, like giant floral arrangements. Keep an eye out for loggerhead turtles cruising the wall, and we’ve often spotted chain morays peeking out from crevices. You’ll see plenty of angelfish and hogfish here, too. For something a bit different, try hugging the sand flats near the shallows on your way back; we’ve found some tiny pearl blennies and yellowline gobies there. The visibility usually sits around 20 metres, offering clear views of the vibrant hard and soft coral tapestry. It’s a comfortable dive for anyone, really, offering a relaxed pace to soak in the beauty of a healthy Caribbean reef.
