We saw many howler monkeys and we even saw an eyelash pit viper! It was down below one of the bridges in a ravine! We saw so many frogs, including a blue jean frog, which was another highlight! We learned about the leaf cutter ants which was just fascinating! Our guide pointed out so many different birds.
Doing the hike with a guide was a great idea, we would have missed out on much of the wildlife we saw had we not had the guide. He found so many hidden gems! And we learned so much about the ecosystem and the history of the area. It was well worth the extra cost for the experience! We also got to hear the volcano rumble while we were there! It was very cool!!!
