Tenorio Volcano National Park

Tenorio Volcano National Park is a protected rainforest area in Guanacaste centered around an active volcano with multiple natural environments. The park features a network of trails that lead to waterfalls, thermal springs, and the distinctive Rio Celeste waterway.

The park was established in 1995 to protect the active volcano and its surrounding natural areas from damage and development. Its creation reflected Costa Rica's commitment to preserving critical rainforest ecosystems.

The Rio Celeste's striking blue water is so remarkable that it has inspired local stories about its celestial origins passed down through generations. This natural phenomenon connects the river to cultural identity and attracts people seeking to understand the place's distinct character.

The park is open during daylight hours and visitors should prepare for wet conditions since rain is frequent and trails can become slippery. Sturdy footwear and water-resistant clothing are recommended to stay safe and comfortable while exploring the area.

At El Teñidero, two clear streams merge and their waters transform into brilliant blue through a chemical interaction between sulfur and calcium carbonate compounds in the rock. This dramatic color change happens right before visitors' eyes as the waters combine.
