The Amazon is the world's largest tropical rain forest. However there are several lesser-known temperate rain forests, such as the Hoh Rain Forest on the Olympic Peninsula. Hoh Rain Forest gets as much as 14 feet of rain a year. The prevalent fog and mist contributes the equivalent of another 30 inches of rain, resulting in one of the world's lushest rain forests, hence its designation as one of the wonders of Washington State.
