Los Tres Ojos National Park is a place of nature and tranquility for all ages, with four lakes—three underground and one that can be observed from the surface. The first spring is called "Sulfur Lake," located 300 meters underground and 4.5 meters deep. It does not contain sulfur; rather, its name comes from the minerals called calcium carbonate or aragonite, which come from a constant drop of water generated by rocks called stalactites, which descend from the ceiling to join with another stone called stalagmite. The second spring in this natural park is called "La Nevera" (Fridge Lake) because of its temperatures of 20 to 21°C (68 to 70°F). The third eye is called "La Damas" (The Ladies' Eye) and is eight meters deep. The fourth and last is "Lago Zaramagullón" (Zaramagullón Lake); its name comes from ducks from Africa that inhabit it for a short time before returning to their natural habitat.
