Colorful reef-current dive

Left-shoulder reef routing, colorful coral, and a current-fed reef slope make Coral Mountain Bay a balanced advanced reef dive.

About Coral Mountain Bay

Coral Mountain Bay is a colorful reef-current dive where the reef on the left shoulder is the main attraction and the fish traffic is the bonus. The site combines hard and soft corals, nudibranchs, and macro life with the chance of whitetip sharks and larger fish in moving water, so it works best for divers who want an active but not chaotic advanced reef. The slope-to-plateau shape gives it a more sculpted feel than a pure wall, and the clearer windows make the coral color pop. This is a polished Maratua reef dive, not a current-hook spectacle.
