Following your pickup from your hotel in La Fortuna Downtown, you will venture to the heart of the Tenorio Volcano. Once having arrived there, you will discover the mystery of the minerals that produce the reaction that causes the river to turn a marvelous light-blue color. You will explore right where the Buena Vista River and Roble River merge, with both rivers originating from the volcano. The colors of these rivers is caused by the different concentrations of minerals. The natural chemicals mix and cause a reaction between the sulfur from the volcano and calcium carbonate from the rain, creating one of the most beautiful attractions in Costa Rica. Later on in your tour, you will be taken to a breathtaking waterfall called the “Bride’s Veil”, which is the highlight of your adventure. You will then be taken to the Tenorio Volcano viewpoint, thermos mineral hot springs, and volcanic mud ponds. At the conclusion of your geothermal experience, you will be returned back to your point of origin in La Fortuna Town.
