Rio Celeste Rainforest Hike is one of the most beautiful and scenic rivers in Costa Rica, located in the lush rainforests of Tenorio Volcano National Park, undiscovered by mass tourism. The park is home to an incredible biodiversity of flora and fauna, including the tapir, wild cats, monkeys, toucans and a vast variety of amphibians and reptiles. Once at the park entry we start the hike through this primary Humid and Rainy Forest, several fauna species and exuberant flora are easily found in these ecosystem. During this 3 hours walk we visit a magnificent waterfall, the place where the river dies with the light blue coloration, hot water springs (swimming not allowed for park’s administrative rules); fumaroles of volcanic gases, where temperatures up to 1500 °F are expelled from time to time, and the “Borbollones”, where exhaust gases at the base of the river give the appearance of boiling water. This tour is recommended for hikers or anyone who loves natural outdoors and owner of a good or normal physical shape.
