The snorkeling in Tonga is very popular. Some of the best snorkeling is off the northwest tip where there is a fringing reef creating protected dive sites. A good alternate dive is on Fafa Island off the north coast of Tongatapu where there is a marine reserve with giant clams. The Fua'amotu International Airport is located on the southeast side of Tongatapu. There are regular flights from Los Angeles, Aukland, Sydney, Brisbane and Melbourne.
