Chato Volcano (called ‘Cerro Chato’ in Spanish), is an inactive volcano that sits in the southeast side of Costa Rica’s most popular and active volcano, Arenal. Chato has a truncated volcanic cone rising to some 1,140 meters, though it hasn’t had any registered volcanic activity for the past 3500 years – about the time when Arenal was just beginning to be born. cerro chato

It is believed Chato first erupted 38,000 years ago. One of its lava flows is now the route to La Fortuna Waterfall. The hill has two peaks, named Chatito and Espina, and a gigantic water-filled crater, the Mount Chato Lagoon.

Flora and Fauna

Cerro Chato, along with the surrounding Arenal Volcano National Park, is home to a wide variety of flora and fauna. Some of the species that inhabit the area are howler and spider monkeys, white-nosed coati, sloth, deer, fer-de-lance, boa constrictors, parrots, parakeets, black vultures, resplendent quetzals, trogon, hummingbirds, motmots and toucans. Plant life includes ferns, heliconia, mountain guayabo, freijo, rosewood, and balsa trees.

Hiking Cerro Chato

The El Chato trail is an arduous yet rewarding five hour hike that passes through lush rainforest and astonishing steep hills. It is almost entirely uphill, and ends at the blue waters of the Mount Chato Lagoon.Cerro Chato Hiking Trail
Being a long and intense trail, we recommend hiring an experienced and knowledgeable guide. Guided tours can be arranged in the town of La Fortuna.

La Fortuna Waterfall

La Fortuna Waterfall (Spanish for ‘the fortune’) is right at the base of the dormant Chato Volcano and drops about 70 meters. It offers some of the most gorgeous scenery in all of Costa Rica. This amazing ribbon of water falls into a great swimming hole, surrounded by lush tropical forest, protected by the local conservation project.
Downstream from the waterfall, there are calmer waters for a more relaxing dip and a lookout point, which is perfect for admiring and taking pictures of the beautiful waterfall.laguna cerro chato
