This river is famed for its shockingly bright blue color, a natural wonder caused by the reaction of volcanic sulfur and calcium carbonate. The result is a stunning powder-blue shade that will leave you in awe.
A hike through the lush rainforest will lead you to a number of incredible sights along the Rio Celeste. Be sure to capture the beauty of the Rio Celeste Waterfall, where the river dramatically cascades into a vibrant blue lagoon. Witness the Tenideros, the confluence of two rivers that merge to create the Celeste, and experience the magic of Poza Azul, the most renowned "dye pool" where the color reaction is at its most intense.
For the best views of the river’s startling color change, we recommend visiting during the dry season, from December to April. During this time, the reactive chemicals create the most vibrant blue, as excess rainfall can dilute the color, sometimes leaving the waters with a less appealing muddy hue.
