Rio Celeste’s turquoise river inside Tenorio Volcano Park

Rio Celeste in Upala is a turquoise river in Tenorio Volcano National Park, in northern Costa Rica. Its colour is the place’s first draw, but the river also brings together waterfall, forest and volcanic terrain in a single route.

Rio Celeste and the colour of Los Teñideros

The river’s most striking section begins at Los Teñideros, where the clear waters of the Buenavista River meet the acidic Quebrada Agria. The colour shift links the river to the volcanic slopes around Tenorio Volcano, and the blue tone remains the feature people remember first.

Rio Celeste is tied to a well-known physical process rather than paint or sediment alone. Suspended aluminosilicate particles scatter light in a way that gives the water its blue appearance, and the river’s name translates from Spanish as sky-blue river.

The waterfall, forest and volcanic terrain

The site includes a waterfall on the Rio Celeste, with water dropping over dark volcanic rock into a pool below. The broader landscape is rainforest on the slopes of Tenorio Volcano, and the river runs through that setting for much of its course.

Rio Celeste is also part of a wider volcanic system that shapes the place without needing ornament. Tenorio Volcano National Park contains the river, the confluence at Los Teñideros and the surrounding forested terrain, all within a national-park landscape that is clearly defined by water and rock.
