For stunning diving in Tuvalu, check out stunning Funafuti Island, then head to Nukufetau Reef - a gorgeous, fringing reef outside the lagoon. The nine islands of Tuvalu are all tiny coral atolls and Funafuti is the capital. Tuvalu is made almost entirely of coral, so diving here is amazing.
The Funafuti lagoon itself is 14 km wide and about 18 km long. Part of the Tuvalu Funafuti Conservation area, it includes reef, lagoon, channel, ocean and islands habitats.
