Unlike the platform reefs closer to shore, these ribbon reefs rise steeply from deep Coral Sea waters, creating a dramatic wall environment on one side and sheltered coral gardens on the other. Snorkellers float above thriving bommies of hard and soft coral in water clarity that regularly exceeds 20 metres, with encounters with massive sea turtles, reef sharks, and schools of trevally common.
