Entrance Bommies - Coral Sea

Kalli’s Reef feels like a secret, even though it’s just a short boat ride to Klein Bonaire. We love dropping in here, watching the sand ripple under the boat before the reef wall comes into view. The coral formations aren't the biggest you'll ever see, but they're healthy and vibrant, especially the big heads of blushing star and lettuce coral. We often spot schools of round scad and jacks cruising past the wall, and the doctorfish and hogfish are almost always milling about. Keep an eye out for the smaller stuff too, like the yellowline gobies peeking from their holes or a shy pearl blenny. The average depth here is around 12-15m, making it a perfectly relaxed second dive. We’d suggest going early in the morning before any wind picks up, when the light really makes the blues pop.
