• Rio Celeste -

The dazzling centrepiece of the Tenorio Volcano National Park, the Rio Celeste is most famous for its shockingly bright blue color, the result of a natural reaction of volcanic sulfur and calcium carbonate, which turns the clear waters a powder-blue shade. Reached by hiking through the surrounding rainforest, there are a number of sights of interest located along the Rio Celeste, most notably the Rio Celeste Waterfall, a favorite photo spot where the river tumbles into a striking blue lagoon; the Tenideros, where two rivers merge in the Celeste; and the Poza Azul, the most renowned “dye pool,” where the reaction is most noticeable.

The river’s startling color change is best viewed during the dry season (December to April), as excess rainfall can dilute the reactive chemicals leaving the waters with a less-appealing muddy hue.

This river is renowned for its astonishingly bright blue hue, a natural marvel resulting from the interaction of volcanic sulfur and calcium carbonate. The outcome is a breathtaking powder-blue shade that is sure to amaze.

A trek through the verdant rainforest will bring you to numerous remarkable sights along the Rio Celeste. Don’t miss the chance to capture the splendor of the Rio Celeste Waterfall, where the river dramatically plunges into a vivid blue lagoon. Observe the Tenideros, where two rivers converge to form the Celeste, and experience the enchantment of Poza Azul, the most famous “dye pool” where the color reaction is at its peak.

For optimal views of the river’s striking color transformation, it is recommended to visit during the dry season, from December to April. During this period, the reactive chemicals produce the most vibrant blue, as excessive rainfall can dilute the color, occasionally leaving the waters with a less attractive muddy appearance.
