Morning mist clings to the rainforest as the van eases away from the coast and the guide begins a running commentary on local crops, climate and culture. By the time the trail opens into the Tenorio area, river water shows the signature, electric-blue hue that earns Río Celeste its fame — a chemical kiss of volcanic minerals and sunlight that seems to push the current forward.

History
The Tenorio area sits on volcanic terrain that has directed river chemistry for centuries; local agricultural practices and protected lands reflect a shift towards eco-tourism in Guanacaste.
Conservation
Tenorio National Park manages visitor access to protect delicate aquatic chemistry and riparian habitat; stick to trails, avoid soaps or sunscreens in waterways, and support local sanctuaries that rehabilitate rather than keep wild animals as exhibits.

Start early to beat crowds
Departure is early; morning arrival at Río Celeste reduces people on the trail and gives cleaner light for photos.
Wear grippy shoes
Trails can be muddy and slippery around the falls — closed-toe hiking shoes with good tread help with short stair sections and roots.
Bring insect protection
Forest sections have mosquitoes and biting insects; apply DEET or picaridin and consider long sleeves for shade-dwelling bugs.
Respect wildlife distance
At the sanctuary and on trails, keep at least several meters from animals; no feeding or loud approach to avoid stress.
Sturdy hiking shoes
Grip and ankle support for muddy, root-strewn rainforest trails.
Light rain jacket
Afternoon showers are common; a packable shell keeps you dry and warm.
summer
Reusable water bottle or hydration bladder
Stay hydrated during the hike — bottled water is provided but extra capacity helps.
Insect repellent and sunscreen
Protects against mosquitoes in shaded forest sections and UV at open viewpoints.
