One of the most popular tourist attractions in Costa Rica is the Parque Nacional Volcan Tenorio. Inside there are amazing beauties like the volcano, catarata Rio Celeste, the blue lagoon and Los teñideros (the stainers/the diers).

The unique color is from a chemical reaction between four different elements. The white strip is the calcium carbonate, one of those four chemicals.

Rio celeste is 36 kms long where it joins Rio frio and loses its color.
