Mist hangs low in the rainforest as the trail narrows and the river ahead brightens to an impossible blue. Hikers follow a shaded path through secondary forest, ferns brushing the knees, until the river makes its signature turn into a sky-colored channel and finally plunges over the Rio Celeste waterfall.

History
Tenorio’s landscape is sculpted by volcanic activity; the park was protected to conserve unique volcanic features, cloud forests, and watershed systems that feed lower valleys.
Conservation
Tenorio is a national park with strict trail limits and rules to protect the river’s chemistry and surrounding habitat — stick to paths, avoid soaps in water, and carry out all trash.
