Fiji is called the “Soft Coral Capital of the World” almost entirely because of the abundant soft coral in the Somosomo Strait. Float with the current past the multicolored outcrops swaying like trees along the aptly named Rainbow Reef or the Great White Wall, a veritable blanket of white coral that’s considered one of the most beautiful and unusual dive sites in the world. Of course, there are colorful fish everywhere—more than 1,200 species—as well as rays, mollusks, and spinner dolphins. Companies on Vanua Levu and Taveuni all lead trips to this underwater wonderland.
