Tonga diving is all about variety and visibility making dive vacations in Tonga popular year after year with divers. World-class diving is available all year round, and it's one of only two places in the world where you can encounter humpback wales during a dive. Our Tongan dive resorts also offer the opportunity to see manta rays and eagle rays, as well as many shark species. The Vava'u Group has excellent drift dives along walls and drop offs and is home to the fascinating wreck of a copra steamer, known as The Clan MacWilliam. Visibility is usually excellent, often exceeding 40m. If you are looking for caves, canyons, caverns and tunnels with vertical walls, fast flowing passes and colourful coral gardens, the Ha'apai Group has everything you need.
