We decided to go ahead with the night tour to have a different experience and it was! We saw several type of frogs, caimans, cocrodriles, spiders, weird insects and the like. They guide was very god at explaining them, at spotting them (and teaching us how to spot them) and he was very good with the safety recommendations. He would take the time to show us the details and allowed us to take some very cool pics. My 9 year old son had lots of fun and we felt like real explorers in the dark.
