La Fortuna Waterfall (Spanish for "the fortune") is in central Costa Rica. In Spanish, it is known as Catarata Fortuna. The waterfall drops about 70-75 meters and is located at the base of the dormant Chato volcano, about 5.5 km outside of the town of La Fortuna, near the Arenal Volcano.

Chato Volcano, sometimes called "Cerro Chato" (spanish for "Mount Chato"), is an inactive volcano in north-western Costa Rica north-west of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. It is southeast of the nearby Arenal Volcano

It is believed Chato first erupted 38,000 years ago during the Pleistocene period and last erupted about 3,500 years ago. One of the lava flows is now the route for La Fortuna Waterfall. The hill has two peaks, named Chatito and Espina. A crater about 500 metres (1,600 ft) wide is filled with a lagoon, Laguna Cerro Chato.

Lake Arenal is a reservoir in Costa Rica, formed by enlarging an existing small lake of the same name by the completion of a dam in 1979. It is located near the Arenal Volcano and the Monteverde cloud forest. Lake Arenal is the key driver in a nationwide hydroelectric project that currently produces the majority of electricity for the entire country.^[1]. Water depth generally varies between 100 and 200 feet (61 m). The communities of "old" Arenal and Tronadora were submerged by the expanded lake.

Mysterious and imposing, in the very bowels of the Tenorio Volcano, manifestations of hidden power transform the union of the Buena Vista and Roble rivers into a sky blue stream, giving birth to one of the most extraordinary phenomenon’s of nature: “Light Blue River”. Along the river we’ll find hot springs, bends of heavenly tranquillity and a waterfall of singular beauty, all surrounded by varied flora and fauna.

The Caño Negro Wildlife Refuge and the Rio Frío are biological humid areas considered to be one of the richest in biological diversity in Costa Rica. Here you can find a great variety of resident and migratory birds plus three different species of monkeys, also iguanas, sloths, turtles and caymans.
