My friend and I did a 4 day jungle tour just outside of Manaus and Kenrick was our guide. He was very knowledgeable of the jungle and taught us many things and was able to help us spot interesting wildlife. I was particulary impressed when he caught a caiman with his bare hands! He spent a lot of time with us and always made sure we were having a nice time and was a lot of fun as well, and he always had good safety practices. He was also able to overcome any obstacles in our path, such as when a fallen tree several inches in diameter blocked the path of our boat and he impressively chopped it down in about 10 min with only a machete! And since he is a native English speaker he was very easy to communicate with.
