    CharacterReef dive

    Mango Bay, tucked into Koh Tao's northern reaches, feels a world away from the island's busier spots. We love coming here for a relaxed, shallow dive, especially when the south end of the island is getting a bit choppy. It’s perfect for divers brushing up their skills or just looking for an easy-going afternoon. Drop in and you're immediately greeted by vast sandy patches interspersed with chunky bommies. Look closely at the sand for blue-spotted stingrays half-buried, or a wary barbeled leatherjacket picking its way along. The staghorn coral here is doing really well, forming thickets where schools of herring scad dart in unison, sometimes so many they turn the light green. On a calm day, the visibility can stretch to a good 15-20 meters, letting you spot the flashes of clown tangs and longfin bannerfish picking at the coral heads. We always suggest keeping an eye out for wavyline rockskippers clinging to the rocks in the shallows – they’re surprisingly endearing. It’s not a drift dive, just a gentle potter, making it ideal for longer bottom times and really soaking in the quiet atmosphere.
