Exclusively for guests over the age of 16, Dream Island Resort is your true adults-only resort in Tonga and the only one of its kind. Stay on the “Island of the King”, ‘Euakafa Island in Vava’u where there are just three beach bungalows and one garden bungalow. All are very spacious with queen beds, an outside ensuite and a private verandah.

Your time on the (almost) uninhabited 'Euakafa Island is a relaxing one with some strong Robinson Crusoe vibes. You can spend your time hiking, watching whales from the beach, snorkelling in the island’s coral reef, and watching birds and flying foxes. Needless to say, this is not the place to be if you're not into providing your own entertainment.

Meal plans are advised, which include breakfast, lunch and a three-course dinner in the dining fale that, admittedly, is in need of some repair after cyclone damage.

Mandala Resort is exclusively available as a seven-day all-inclusive package through TradeWinds.

If the resort is your priority, you're bound to find the perfect balance of adventure and relaxation, from making use of the water toys available to enjoying yoga sessions on their purpose-built deck. Your stay will be in one of the six hand-crafted fales, including two luxurious treehouses.

The resort also offers an upmarket dining experience with all meals and drinks included, including a Tongan cultural feast and entertainment on the neighbouring island.
