Arenal Oasis Night Walk offers a chance to see Costa Rica’s incredible nocturnal wildlife in a relaxed, natural setting. For $70 per person, you get about three hours of guided adventure, starting in the early evening from La Fortuna. The tour visits Arenal’s only wild frog sanctuary, where you’ll encounter a vivid array of frogs, insects, and other rainforest creatures that come alive after sunset. Plus, round-trip transportation is included, making it a hassle-free experience for visitors staying in La Fortuna.
What immediately draws us to this tour are two standout features. First, the expert guides—from the reviews, it’s clear that guides like Jason and Vitor are highly knowledgeable, with a knack for spotting even the shyest creatures.

What Makes This Tour Special?
This guided night walk in La Fortuna is a truly engaging way to see Costa Rica’s wildlife after sunset. The focus on Arenal’s only frog sanctuary provides a rare opportunity to observe at least 28 frog species during their most active hours. The tour takes place on flat rainforest trails, making it accessible for most visitors, and the gradual transition from daylight to darkness adds a magical touch to the experience.
The experience starts with pickup from your hotel, which removes the hassle of navigating unfamiliar roads after dark. Once at the sanctuary, the naturalist guide leads you along the ponds and trails, pointing out creatures that would otherwise remain hidden. The guides’ ability to locate animals is frequently praised—”Jason was a very knowledgeable guide,” one reviewer noted, describing sightings of vibrant frogs, a sleeping sloth, and even a fer de lance snake.
The Itinerary in Detail
The tour begins at 5:30 pm, when you’ll be picked up from your La Fortuna accommodation. The route takes you to the private wildlife reserve maintained by the Rojas Bonilla family, who carefully manage native plants to create ideal frog habitats. The ponds are spring water-fed, attracting a diverse frog population that comes alive as the sun sets.
Once at the sanctuary, your guide will lead you on flat trails, making it comfortable for most. You’ll walk past frog ponds and deeper into the rainforest, where you’ll hear the symphony of insects, frogs, and perhaps the distant call of a howler monkey. The highlight is witnessing colors and behaviors that you rarely get to see in daylight.
Some of the most common sightings include red-eyed tree frogs, rain frogs of various types, and occasionally more elusive species like snakes or sloths resting in trees. Reviewers shared that even in rainy weather, animals were active, and the guides’ skill in spotting creatures enhances the experience.
Wildlife Encounters and Authenticities
Expect to see an impressive variety of rainforest life. As one guest put it, “We saw many species of frogs, a snapping turtle, a large venomous snake, and a sloth with a baby.” The guide’s ability to spot creatures in low light, combined with your provided flashlight, makes all the difference.
The tour isn’t just about spotting animals—it’s also an educational experience. Guides share interesting facts about each species, their behaviors, and their roles in the rainforest ecosystem. For instance, learning that the frogs are living in habitat carefully created by local farmers adds a layer of appreciation for conservation efforts.
