A private full-day hike to Río Celeste combines rainforest walking, a rare blue river caused by volcanic chemistry, and a restorative dip at nearby waterfalls and hot springs. Expect a 9–10 hour day with a 4-hour, moderately strenuous hike, hotel pickup, and lunch.

You wake before dawn and the van eases out of Tamarindo into a country smeared with coffee plantations and grazing cattle. By the time the road narrows and the air thickens with humid green, the rainforest has already taken over—ferns brushing your calves, motmots calling from high branches. The trail to Río Celeste threads through volcanic soil and moss-laced boulders until, at the Teñidero, the river seems to change its mind—two colorless streams collide and, by chemistry and light, the water turns an impossible blue that dares you to look away.
