Fog lifts off the rainforest as you step onto the trail and the sound of the Celeste River starts to insist on your attention. The path climbs through mature tropical forest, roots and ferns pressing in, until a sudden cleft in the canopy reveals water the color of crushed turquoise glass — Rio Celeste’s famous turn from clear stream to impossible blue where two brooks meet and volcanic minerals react in sunlight.
