The trail begins before sunrise: a small bus threading out of San José while the central valley still holds its night air. By midmorning the forest opens — a cool tunnel of moss, ferns and cedars — and the river announces itself in a color so blue it feels deliberate. The Celeste River seems to push forward, daring you to walk closer and find the place where two currents meet and chemistry turns water electric.
