Otto’s Reef - Kimbe Bay
Otto's Reef is a coral ridge in Kimbe Bay where the reef drops off into deeper water. We often find schooling fusiliers here, a good indicator that pelagics might be cruising past. Keep an eye out for grey reef sharks and the occasional silvertip. It's a great spot for divers hoping to see larger species rather than macro life.
