About Coral Mountain Bay
Coral Mountain Bay is a boat-access reef dive in the Derawan and Maratua area, usually run as a guided pass along a coral-covered slope. It mixes broad hard-and-soft-coral coverage with macro life such as nudibranchs while still offering the chance of bigger fish and whitetip reef sharks when current picks up.
