We had lunch at the Jungle lodge then rested in the hammocks, falling asleep to the resounding call of the howler monkey. While it is an amazing and eerie sound, it is surprisingly relaxing, and I was able to fall asleep to it. The call of the howler moneky is one of the coolest things I have ever heard, its really hard to describe, but you are amazed that it is coming from a living thing, several miles away.
