You step onto a rainforest floor that smells of wet earth and citrus; a chorus of birds punctuates the climb as the trail narrows and the canopy tightens. The Rio Celeste appears like an impossible ribbon of turquoise, daring you to follow it upstream toward the Tenorio Volcano slopes.

You step onto a rainforest floor that smells of wet earth and citrus; a chorus of birds punctuates the climb as the trail narrows and the canopy tightens. The Rio Celeste appears like an impossible ribbon of turquoise, daring you to follow it upstream toward the Tenorio Volcano slopes.
The trail is a compact lesson in local geology and history: volcanic minerals and a rare chemical reaction at the "Teñideros" create the river’s blue tone, while the surrounding forest sits on old lava flows that shaped the valley. Indigenous Huetar people once moved through these highland forests; today small farms and ranches in nearby Bijagua reflect a rural culture rooted in the volcano’s foothills.
On a typical day hike you'll cover about 7 km (4.3 mi) on uneven rainforest trails with moderate elevation changes, stopping at the Celeste Waterfall, the calm Blue Lagoon, thermal springs and a volcano viewpoint. Guides point out how sulfur and sulfate help color the water, and keep an eye out for toucans and capuchins that often animate the canopy.
Practical guidance: start early to avoid afternoon rain and crowds, wear grippy hiking shoes and a lightweight rain jacket, and bring at least 2 liters of water—the trail can be muddy and slippery. Expect a full-day outing (6–8 hours including transfers and breaks); lunch is usually provided. Respect marked paths, carry out trash, and be ready for strong sun on exposed viewpoints—this hike rewards preparation with one of Costa Rica’s most singular river spectacles.
The core trail is about 7 km (4.3 mi) on uneven rainforest paths; with transfers, stops and lunch expect a full-day outing (6–8 hours).
Yes—the river’s blue comes from a chemical interaction between volcanic minerals at the Teñideros; the effect is natural but can vary in intensity with flow and light conditions.
Children may join but must be accompanied by an adult; guides and providers commonly require a minimum group size and recommend good mobility for participants.
Lunch and bottled water are typically included, but bring snacks, personal water if you prefer more than provided, and any dietary requests noted at booking.
