Cocos Island receives an average of 25 feet of rainfall per year, resulting in a covering of lush green foliage. Waterfalls abound, of which there are up to 70 falls of varying sizes during the peak of the rainy season.
The island also supports a verdant, high-altitude cloud forest. Rare for a small island, this is made possible by dramatic topography, abundant rainfall and surplus water stored in the porous reservoirs of the island itself. This extraordinary island ecosystem is unique to Cocos alone, of all the islands of the Eastern Tropical Pacific (Clipperton, the Revillagigedos, the Galapagos Islands, and Malpelo). Due to the heavy rainfall, the island is also prone to frequent landslides, which helps to account for its irregular geography.
