Posted June 2017
Costa Rica’s Blue Rivers are truly unique natural wonders. They are scarce in Costa Rica and the world. Blue Rivers are formed by minerals created by a volcano’s underground activity and have become one of Costa Rica’s top attractions, for both tourists and scientists. Collectively they represent a small part of the beauty in the Costa Rica masterpiece; just imagine, tubing, swimming or soaking in a Blue River, especially under a waterfall in the rain forest! Words simply can’t explain their magical allure.

For those curious for more, we hope these blogs help satisfy that thirst for knowledge and your choice of blue rivers to visit.
