The Hawaiian Islands are the world’s most isolated land mass, and Maui, known as “The Valley Isle”, is the second largest.
Maui’s coral reefs are categorized as fringing reefs, and several dive sites feature underwater caverns and archways formed by ancient lava flows.
About 1/5 of all fish and 1/4 of all invertebrates in Hawaii are endemic, occurring nowhere else on Earth. Few locations compare with Hawaii in number of unique species.
Hawaii’s waters are cooler than many other reef areas of the Pacific. Temperature varies between 73 and 83 degrees. A wetsuit is recommended.
