Dusk folds over Arenal Oasis and the rainforest exhales: leaves whisper, water mirrors the last light, and frogs begin to claim the night. On the Frog Watching Night Walk a trained naturalist leads small groups along flat, lantern-lit paths that skirt frog ponds and understory pools. The chorus builds—single notes answering from the leaf litter—while glass frogs and red-eyed tree frogs peek from the damp foliage, and the forest seems intent on showing its hidden residents.
Verified experiences and guided adventures in the surrounding area.

Dusk folds over Arenal Oasis and the rainforest exhales: leaves whisper, water mirrors the last light, and frogs begin to claim the night. On the Frog Watching Night Walk a trained naturalist leads small groups along flat, lantern-lit paths that skirt frog ponds and understory pools. The chorus builds—single notes answering from the leaf litter—while glass frogs and red-eyed tree frogs peek from the damp foliage, and the forest seems intent on showing its hidden residents.
The Arenal area sits on volcanic soils that help sustain dense, humid forest pockets—perfect for amphibians. This property operates as a local frog sanctuary, part of broader conservation and ecotourism efforts that grew with La Fortuna’s modern tourism around Arenal Volcano. Guides here blend natural history with practical fieldcraft, teaching visitors to read eye shine, listen for mating calls, and recognize amphibian habitats without disturbing them.
Practical details: tours begin at 5:45 p.m., run about two hours, and follow well-marked, flat trails—suitable for most fitness levels. Flashlights are provided, reservations are required, and groups are capped small for minimal disturbance (max 8). Closed-toe shoes are mandatory; sandals aren’t allowed. Expect muddy patches in the rainy months and bring a light rain layer and insect repellent. Move slowly, keep voices low, use dim or red light, and never handle frogs—amphibian skin is fragile and susceptible to oils and salts from human hands.
This is an intimate, low-impact encounter: you’ll leave having heard the rainforest speak after dark and with a clearer sense of why these small creatures matter to the whole ecosystem.
Yes—tours are family-friendly but expect low light and a slow pace; parents should ensure kids wear closed-toe shoes and stay close to the group.
Flashlights are provided, but bringing a personal headlamp with a red filter is helpful for hands-free viewing and less disturbance.
No—handling is prohibited to protect amphibian skin and prevent disease transmission; guides will point out animals and explain safe viewing practices.
Full refunds are available if you cancel at least 24 hours before the scheduled start; tours may be canceled for bad weather.
