    CharacterDrift dive

    Seromadopo sits in a sheltered bay, just a quick boat ride from Kusu Island. We’ve found it’s a reliable spot, a sloping reef with big boulders draped in healthy coral. Visibility usually holds around 21 metres, letting you really appreciate the coverage here. Keep an eye out for the resident blacktip reef sharks gliding past, and schools of fusiliers sometimes swirl so thick they dim the light. On the macro side, we’ve consistently spotted Blackbelly Pygmygobies and even a few Candy Crabs tucked into the Staghorn. You can get some current here, especially around tide changes, so it’s a good one for intermediate divers who don’t mind a bit of a drift. It’s a solid dive for anyone looking for that classic Indo reef vibe without being overly challenging.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
