On the Big Island of Hawai’i, in the heart of an area known as Kaloko-Mauka, is the only Cloud Forest in the U.S.A. Many ask, “what is the difference between a cloud forest and rain forest?” A cloud forest is generally a cool tropical/subtropical, evergreen, montane, or moist environment. Sometimes called the fog forest in a higher elevation between 3,000 to 8,000 feet and characterized by cloud cover, usually at the canopy level and only found in tropical areas with tall mountains. It feels like you are in a humid cloud. Very few cloud forests exist in the world today.
