“We saw four red-eyed tree frogs, a sleeping hummingbird and a tarantula the size of my hand. Our guide found all of them in the dark.”
Laura M. · Madrid


Small-group walks by day and after dark, led by naturalists who know which leaf the frog sleeps under.
Costa Rica · Arenal lowlands
Most of the forest is hiding in plain sight. A trained eye turns a wall of green into frogs, sloths and birds.
Field guide
Two walks
Morning light in the canopy, when birds are loudest and sloths come out to warm up. A slow walk with a spotting scope, stopping for whatever the forest shows us.
Often seen: three-toed sloths, keel-billed toucans, poison dart frogs, leafcutter ants, heliconias.
Book the day walkWe head in at dusk with red-light torches, when the night residents wake up. Quieter, slower and full of eyes that shine back at you.
Often seen: red-eyed tree frogs, two-toed sloths, glass frogs, tarantulas, sleeping birds.
Book the night walkAfter dark
Frogs start calling, sloths start moving and the leaves light up with things you would walk straight past in daylight.
Before you go
Your guides
Our guides grew up between the volcano and the river. They are certified naturalists who spot a frog by its call and a sloth by the way a branch bends.
Groups stay small so everyone gets a turn at the scope and nobody scares the wildlife off.

“Two sloths and a pair of toucans in the first hour. The scope photos on my phone came out better than my camera.”
James T. · Toronto
“My kids still talk about the glass frog. You could see its heart beating.”

FAQ
Yes. Trails are well known to our guides, groups are small, and everyone gets a flashlight. We keep a respectful distance from snakes and never handle wildlife.
