About this site
Horseshoe Reef is the most visited reef off the south shore of Oahu. It still offers an expanse of healthy corals, and these corals provide homes to octopuses, eels and an incredible variety of fishes and invertebrates.
Looking between the corals, divers may be lucky enough to spot imperial nudibranchs, and the elusive dragon moray is sometimes seen here too.
