Night Walk in Arenal Oasis Frog Sanctuary

Step into the rainforest after dark and witness a completely different world come alive during your Night Walk in Arenal. This unique nighttime experience takes place at Arenal Oasis, home to the region’s only wild frog sanctuary. Guided by the soft glow of your flashlight, you’ll explore the rainforest at the exact moment when its most fascinating creatures are awake, active, and ready to reveal their hidden world.

At least 28 different frog species inhabit the crystal-clear ponds of this private ecological reserve — including the iconic red-eyed tree frog, the delicate glass frog, and vibrant dart frogs. The Rojas Bonilla family, guardians of this conservation refuge, have spent years protecting native plants and freshwater habitats, creating the ideal environment for frogs and countless other nocturnal animals. It’s one of the reasons the Night Walk in Arenal has become a favorite among nature enthusiasts.

As you follow your naturalist guide along flat, easy jungle trails, the rainforest comes alive with sound: the gentle rustle of leaves, the rhythmic chorus of frogs, and the distant calls of owls and night birds. Along the way, you may spot sloths, armadillos, owls, and even insects that glow in the dark — unforgettable sights that make this Night Walk in Arenal both magical and educational.

This experience offers an intimate look into Costa Rica’s nocturnal ecosystem, perfect for families, photographers, wildlife lovers, and anyone curious to see the rainforest from a completely new perspective.
