Tenorio National Park is best known for the beautiful Rio Celeste, whose light blue waters are caused by the emanation of sulfur and the precipitation of calcium carbonates.
Primary cloud forest and rainforest covers the park, which abounds with flora and fauna species in multiple life zones, innumerable rivers, waterfalls, thermal hot springs, and Laguna La Danta (Tapir Lake)
The Tenorio Volcano, with multiple craters, and Montezuma Volcano with twin craters, are both assumed to be dormant, with no eruptions in recent history.
