Rio Celeste - Tenorio Volcano National Park

Lake Arenal in the Costa Rican highlands is a very big lake. And north of the western edge of the lake is Volcan Tenorio one of six active volcanos in the country. Río Celeste is undeniably one of Costa Rica’s most photogenic sights, and it’s all thanks to the volcano: sulfur emissions from the volcano plus calcium carbonate in the precipitation creates unbelievably blue water. You have to see to believe! It’s all part of a visit to Tenorio Volcano National Park.
