My husband and I booked the 27 May Fincas Naturales night walk and were the only people on the tour. The preserve (aka Manuel Antonio Nature Park and Wildlife Refuge) is across from the Si Como No Hotel. We saw eight species of frogs including: dusty glass frog, gladiator frog, common rain frog, masked tree frog, red eye tree frog, long snouted tree frog, bull frog, and hourglass tree frog. There were red eye tree frogs all over the preserve. We also saw an eyelash pit viper, tarantulas, cane toad and a kinkajou. Our guide, Johnny, was one of the best and enthusiastic tour guides we had in Costa Rica. Would highly recommend this tour.

We did this on our last night in Manuel Antonio and we're glad we did. We a lot of frogs, mostly Gladiator and Green tree frogs as well as some toads. The insects that were out were pretty amazing, several Walking Sticks, Katydids and even a tarantula. The crocodiles and caimans were interesting but we had seen both in the wild near Tortuguero which was much cooler. We were in a small group, 7 of us including the guide and as a result there was plenty of opportunity to interact with the guide and ask questions. It was fun and a very safe and educational way to see the jungle at night.

We arrived to be one of 3 groups moving through this rather contrived jungle setting alongside one of the busiest, noisiest road in the area. The facility ,bathrooms are not maintained very well......looks like not much had been done for 20 years.
We did see a few tree frogs, 2 small snakes in a bamboo grove and pond area.
they also have created several concrete ponds which house captive caymans, and crocodiles which are supposed to be re released to the wild. doubtful, they have been there for quite a while. We have seen much more wildlife and frogs etc during a night hike in Monteverede........or adjacent to where we are staying.

It has some educational value for those who really have never experienced nocturnal habitats at all in a tropic setting. However the $40 peer person admission was really a waste......would have rather donated the money to preserving habitat.

guide was somewhat knowledgeable about names and species....but really only had knowledge to answer the most superficial questions.

Pretty sure this was the place where we took a nighttime jungle tour to see frogs and bugs. Not everyone's cup of tea, but super interesting with knowledgeable guides (Emilio!). It was fun to see the jungle from a different perspective.
