Getting to Tonga
The hub of international travel to Tonga is Fua’amotu International Airport on the main island of Tongatapu. Several airlines offer direct flights to Tongatapu from Australia, New Zealand, American Samoa, and Fiji. From Tongatapu, smaller domestic airlines provide flights to outer islands like Ha’apai, Vava’u, ‘Eua, and the Niuas. The other option is to take a public or private boat, which can get you to any of the island groups in 1-2 days depending on your destination.
Top Snorkeling and Diving Sites
Spread across Tonga’s island groups are seemingly endless reefs, caves, walls, wrecks, and marine-life-rich lagoons perfect for diving and snorkeling adventures. Here are some of the top spots favorite among visitors and locals alike.
Ha’apai Islands
The 62 Ha’apai Islands between Tongatapu and Vava’u offer divers excellent visibility, dramatic underwater topography, and schools of pelagic fish. Two premier sites are Coral Gardens, known for its spur and groove coral formations, and laid-back Sandy Island Resort, where you can snorkel straight off the beach to a vibrant reef.
Vava’u Islands
In the beautiful Vava’u archipelago, don’t miss snorkeling with humpbacks on a whale swim tour or exploring the island’s many sea caves. Top sites include Swallows Cave, home to reef sharks, barracuda, and clouds of Anthias, and the massive Mariner’s Cave filled with parrotfish and unicornfish.
