    StandoutExceptional marine biodiversity

    Anita’s Reef, near Koh Similan, offers a gentle drift over a sloping coral reef. It’s a comfortable dive, usually with mild currents, making it a good choice for newer divers or those looking for a relaxed exploration. We often spot leopard sharks resting in the sand channels here, alongside schools of snapper and fusiliers weaving through the bommies. Keep an eye out for octopus tucked into the coral at shallower depths.
