Diving in Tonga
The 176 islands of Tonga are clustered in three primary groups, with the capital and most of the population on the southern island of Tongatapu. Some 200 miles to the north is the Vava’u island group, and the Ha’apai group lies in between. Humpback whales migrate to these warm waters every year between July and October to mate and give birth. Most whale encounters take place off Vava’u, where the volcanic hills of the island block provide shelter from wind and waves, creating ideal conditions for mother whales to nurse their young. All encounters are free swims using mask and snorkel.
Whales are only one aspect of the diving scene in this island group, which includes more than 40 small islands. Surrounding the maze-like cluster of islands are miles of shallow lagoons loaded with coral heads and intricate reef structures, as well as steep outer reef walls that are washed in some of the clearest waters in Oceania. With only a few dive operations and light diver traffic, there is little pressure on dive sites, many of which lie less than 20 minutes from shore. Reefs blend the hard coral profiles of the islands of Tahiti with the colorful soft corals of Fiji, which lies some 450 miles to the west. Many sites are also noted for intricate underwater landscapes that include networks of caverns, caves and tunnels. These recesses and wrinkles in the reef create abundant habitat for small marine life, providing ample opportunities for macro life enthusiasts. Signature finds include mandarinfish, seahorses, pipefish and several hundred species of crustaceans and nudibranchs. Sites on the edge of open water add spotted eagle rays, schooling jacks, barracuda and tuna, pods of dolphin and a variety of sharks. Neiafu Harbor is home to an excellent wreck dive, the Clan McWilliam. This 425-foot freighter caught fire and sank in 1924, and remains upright and intact in depths from 60 to 120 feet. Now covered in nearly a century of growth, this iron reef swarms with fish and hides shy creatures such as Wobbegong sharks. Less visited than Vava’u are the islands of Ha’apai, which offer near-virgin diving on sites that include everything from coral bommies to offshore pinnacles, along with reefs ridded with swim-throughs, tunnels and arches. A unique site is the Hot Spring Cavern, where a hydrothermal vent fills a submerged cavern with volcanically-heated water.

Culture and Customs
Tonga is the only remaining Polynesian Kingdom. King Tupou V is the current heir to the throne, but the country is governed according to a constitution set down by his great grandfather. Tonga's people retain the friendly and welcoming traditions of their ancestors. The pace of life is relaxed and easy going, blending elements of traditional hospitality with conservative Western values brought by Christian missionaries. Family comes first, and observance of the Sabbath a close second. But these are not somber people. Tonga is renowned for its musical and dance traditions, but pop music is equally enjoyed. Islanders have a friendly greeting for everyone who passes by, and young and old will stop what they are doing to run outside to celebrate the cooling waters of a passing rainstorm. English is widely spoken, but you will still hear snatches of the Tongan language on the streets and when visiting more remote locations. As in Fiji, the Kava ceremony is a central tradition, and something every visitor should experience at least once. The islands themselves are a diverse mix of high volcanic peaks and low-lying limestone ridges that cluster around turquoise lagoons. The economy remains centered on agriculture and fishing, but tourism is beginning to make contributions as well. Resorts are mostly small and subtle affairs that nestle into palm groves set against white sand beaches.
