    StandoutExceptional marine biodiversity

    Johnson's Reef in the Andamans offers a pleasant dive, a good spot for a relaxed morning. You’ll find healthy patches of coral here, home to plenty of Nagasaki damsels darting about and schools of blue-green chromis providing that constant shimmer. We’ve often spotted various wrasse species cruising by, and if you’re patient, you might even catch a glimpse of a Sangi cardinalfish tucked into the reef. It’s not the most dramatic dive in the region, but it’s a solid choice for an easygoing drift or a second dive, suitable for divers looking to unwind and soak in some healthy reef action without too much fuss.
