Starting at $55 per night


This Arenal Oasis Night Hike Tour is an excellent evening activity for families and nature lovers of all kinds. As remarkable as the rainforest is during the day you will have seen only half the sights the forest has to offer. Have you ever noticed that after tucking in for a nights’ sleep in Costa Rica, the forest sounds seem to get louder? Night hikes cast away the mystery of darkness and reveal some amazing nocturnal creatures.

The hike is hosted at Arenal Oasis Eco-Lodge, a hotel and nature reserve that is dedicated to preserving the surrounding ecosystem. Specializing in the conservation of frogs, they have carefully designed Arenal’s only frog sanctuary, providing the perfect environment for frogs to reproduce, thrive and be seen by enthusiasts from around the world. The frog sanctuary contains beautiful native plants and fresh spring water ponds nurturing their natural habitats.

You’ll be picked up from your hotel and driven to Arenal Oasis Eco Lodge, where the night hike tour will start around sunset. Here you will meet your certified naturalist guide who will provide you with a flashlight and tell you about what you might see in the area before setting out on the well maintained trails winding through the rainforest. Your guide will be quick to point out any glow-in-the-dark creatures like phosphorescent fungi or you may discover a few fireflies on your own.

As you pass through the frog sanctuary your guide will shine the light on a variety of colorful tropical frogs species. Have you ever seen a red-eyed tree frog? The bulging red eyes are the most distinguishing feature of this unique amphibian. Glass frogs typically are found at this site too. You’ll know a glass frog when you see one. Its body looks as transparent as glass, allowing you to see all of the veins and internal organs throughout its body.

It has been estimated approximately one third of the world’s frog population has become extinct since the 1980s. Scientists are concerned because frogs represent the health of the overall food chain that can affect the balance of nature. Genetic defects have rapidly increased since the 1990s, thought to be caused by stressors placed on the natural environment. There is a worldwide effort to protect frogs and other environmental indicators as well as preserve their natural habitats which is the goal of the Arenal Oasis Frog Sanctuary.

This interesting night hike tour includes transportation from the La Fortuna area, entrance fee, bilingual naturalist guide, flashlights and bottled water. Please wear comfortable clothes, long pants, enclosed hiking or tennis shoes, rain gear, camera and bring bug repellent. One way transportation to the Arenal Oasis Eco-Lodge can be between 15 and 45 minutes depending on the location of your hotel. Combined tour time with hike and round trip transportation can take between 2 to 3 hours.

Our guide was very knowledgeable. Saw a great variety. My flashlight could have been brighter but that didn’t hinder the experience. . The guide even taught me tricks to using my phone camera and took some pics for me.


We had Jason again for this tour. Half way through we had a very close encounter with a Flur De Lance snake. Pretty exciting.


The tour was good. It rained hard that evening so that made seeing animals more difficult.


We were in a small group with an excellent guide - we were in the 'park' looking at frogs, spiders etc longer than any of the other groups.


An amazing experience!!


Great tour if you like frogs. Our guide was a great cameraman and some of our pictures look just like the ones on here!


Great tour, great guide. We saw so much wildlife. Especially frogs. And he found and brought out a bullet ant on a stick. Amazing! Wonderful and the guide even took great pictures for us. Guide was extremely knowledgable. Excellent!!


Our guide Juan was super knowledgeable and we had a great time! I feel like we learned a ton and we’re able to see so many amazing animals/insects that we would have otherwise never seen. The trail was a bit crowded, but that was understandable given that it was such a busy time of year overall. Juan did a good job of keeping the group spacing and finding amazing things for us!


this tour was my favorite. we saw so many critters. Daniel was excellent with the 4 yo in the group and a wonderful guide


Oscar, our guide, was fantastic. He is a biology teacher during the school year so he was very knowledgeable. Our tour was the first one on the trail that night so we saw lots of wildlife, fer de lance, so many frogs, eye lash viper, spiders, leaf cutter ants....


Saw so much wildlife, our guide was fantastic and engaging


A lovely experience. The guide was very knowledgeable


Unique and safe thanks to the guide.


On the actual day the excursion was cancelled because of thunder and lightening however we went the following day, had a super guide and a most wonderful time. Again exceeded expectations.


This was a great tour and the guide was very knowledgeable. Our kids especially liked.


This was really great. We saw and heard loads of frogs, and the guide was very skilled in getting good photos through the scope. It was quite a short walk but it was excellent.


Very knowledgeable guide who helped take fantastic photos of the frogs.


We saw everything from venemous creatures to so many frog species and the famous red eyed tree green tree frog. AMAzing and the guide was too good to be true.


The guides were very patient with the boys and very knowledgeable.


The tour was great and so was our guide. Transfer was a little late but worked fine otherwise. Unfortunately, we were in Fortuna in the afternoon and could have met up with the guide there or driven to Oasis on our own. Instead, we rushed back to the hotel, just to drive back with the guide who then had to drop us off at the hotel after the tour (1/2 hour each way)


I was not expecting to run into so many spiders 😂 the rest was wonderful! The guide was very knowledgeable we moved at a good pace and got to see wonderful nightlife frogs


Best night tour of the trip.


I would highly recommend this tour and the guide . He was really informative and we saw a lot of different frogs ( which is what you expect on such a tour)


Guide was very willing to take pics for everyone


Guide was fanatastic and excited to share his knowledge on the critters we discovered.


We saw many frogs and got lots of photos. Our guide worked hard to try to find things for us.


Absolutely wonderful. We say 18 different species of frog, insects, and a poisonous snake. Guide was great. We have pictures that are absolutely terrific.


Guide was great. We got some great close up photos.


Even in the rain this tour and the guide were excellent.


The tour was the best night walk of the trip. The guide was great and the location was perfect.


I was part of a small group which limited the opportunities to take good photos since by the time everyone had a chance to take photos the frogs were showing stress from the flash light. I would have preferred a more personalized tour that would have given me more time to get the right photos.


I did expect to see more different types of animals, but I was still pleasantly surprised at the things we did see. The only reason why the overall experience wasn't a 10 was because I was afraid a spider would fall on me but that is not the tour's fault. Still was a very eye opening experience and I wouldn't give it up if I had the chance.


Our guide even climbed a tree to try to show us some frogs. We had a great time!


I thought we would see at least one animal or something besides spiders, millipede, one snake and frogs


Gerald was excellent


Good guide-- satisfaction will depend on what animals are out that night. We did fine.


Good time very informative, great guide. Highly recommended.


Our guide was extremely knowledge and made the experience interesting for the whole family


It was a pretty neat tour. We saw some cool wildlife with a very knowledgeable tour guide.




Wish we had stayed at Arenal Oaysis.
