Scuba Diving in ‘Eua

Tonga’s second-largest and oldest island is one of the top scuba diving locations in the kingdom. ‘Eua is a 40-million-year-old island that has formed dramatic cliffs, vast caverns and tunnels that divers can explore. The diving here is so good, in fact, that dive operators from the mainland, Tongatapu, are making the one-hour trip to ‘Eua to show travellers the amazing underwater seascape. Match that with the whales singing in winter or with seeing any of the 1,500 fish species living in these waters and you have a dream dive!
