In Costa Rica, dozens of mountain springs, streams, and rivers snake through the forest, and with so much freshwater, Costa Rica has managed to meet a significant portion of its energy needs through the generation of hydroelectric power. As runoff moves through lush terrain on its way out to sea, hundreds of cascading waterfalls can be found throughout the rainforests and mountainous areas. Numerous waterfalls are unknown or remain closed to the public, but many breath-taking ones make great destinations for a day hike and refreshing afternoon swim.
