More ways to explore the area's outdoor wonders
You reach the trailhead with humidity already clinging to your shirt and the rainforest breathing around you — leaves drip, birds chitter, and the river ahead seems to glow even from a distance. The Río Celeste trail threads through primary and secondary forest, climbing gentle ridges and crossing streams until the water itself steals the show: an almost impossible sky-blue that deepens as you move upriver toward the chemical confluence.

Good traction matters
Trails get muddy and slippery after rain—sturdy hiking shoes or light boots improve footing on wet roots and boardwalks.
Protect the river
Do not use soap or sunscreen before entering any streams; even small residues can alter the river’s chemistry and color.
Carry extra water and snacks
Though the tour provides bottled water and lunch, bring a small daypack with additional fluids and energy bars for the uphill sections.
