You step off the van into humid air thick with green — the rainforest pressing in from both sides and the distant rumble of water guiding you forward. The trail climbs and dips, roots and volcanic rock underfoot, until a pale, impossible blue appears between trunks: Rio Celeste, where two mineral-rich streams meet and paint the water sky-bright.

History
Tenorio Volcano and its watershed have been protected as a national park to conserve volcanic terrain and the headwaters feeding Río Celeste, supporting local conservation and eco-tourism.
Conservation
Stay on marked trails and avoid bathing or using soap in the river—the blue color is chemically sensitive and upstream activity affects water clarity and color.
Reserve your spot on the Rio Celeste and Tenorio Volcano Hike with Lunch today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Sturdy, grippy footwear
Trail surfaces are often wet and rooted; closed-toe hiking shoes with good tread reduce slips on volcanic rock and boardwalks.
Start early
Morning light enhances the blue color and wildlife activity; afternoons bring more rain and crowds at the main viewpoint.
Bring insect protection
Tropical rainforest insects are common along shaded sections — use DEET or picaridin and cover up during dawn/dusk.
Carry at least 1.5L water
The hike is moderate but humid; hydrate before and during the walk and bring electrolyte snacks if you’ll be warm.
Hiking shoes
Provide traction on wet roots, mud and volcanic rock found on the route.
Light rain jacket
Quick, lightweight protection against frequent showers in the wet season.
winter
Reusable water bottle (1.5L+)
