Right in the center of the mountains, with crystal water, which are an intense turquoise blue there are several hot springs along the way that are very inviting places for tourists to relax. This is the Río Celeste de Guatuso, which is also known as Teñidero. Located on the northeast foothills of the Tenorio Volcano, some 26 kilometers from San Rafael de Guatuso. The color of the water is a product of a dye that runs from the rocks and gives it an attractive tone. To see this you will need to take the road in between San Rafael de Guatuso and Upala County; although, if you want to walk through the mountains to the source it is 5km to the south of the Río Celeste community. Be careful with the hot springs as the temperatures are very high, and visit the majestic 15 meter waterfall that is perfect to go bathing. The river, with its dyed waters is approximately 36km in length.
