You step off the air-conditioned transfer into the humid hush of lowland rainforest, and the trail immediately tightens like a story pulling you forward. Leaves drip overhead; a river ahead murmurs an impossible blue that seems to have been painted into the gorge. The walk to Rio Celeste’s catarata is a steady climb through shaded soil, volcanic boulders, and trunks slick with moss, while your naturalist guide points out poison dart frogs and the slow blink of a sloth in the canopy.

Footwear for wet trails
Wear closed-toe hiking shoes with good tread; volcanic rock and mud create slippery conditions, especially after rain.
Protect your camera
Bring a lightweight dry bag or waterproof case—the waterfall spray and sudden showers can soak gear in minutes.
Hydrate before the hike
Carry at least 1–2 liters of water per person; humidity and uphill sections raise effort and sweat rates.
Respect wildlife viewing
Stay quiet at sloth hides and avoid flash photography; guides will point out observation spots to minimize disturbance.
Sturdy hiking shoes
Good traction reduces slips on muddy or volcanic-rock sections of the trail.
Light rain jacket
Quick showers are common—waterproof layers keep you comfortable and protect gear.
