I spent a week with Cesar as my guide in the Loreto region of the Peruvian Amazon in 2005. It was an amazing experience. He is very knowledgeable about the flora and fauna of the Amazon and the best times/means to find wildlife. Cesar was interested in what I wanted to get out of my stay and was very adept at helping me achieve those goals, which mainly were experiencing the many aspects of the jungle and documenting wildlife and local human culture. He is also very easy to get along with. I heartily recommend him as a tour guide!
Cesar was hired to help guide our 2012 National Geographic Amazon Express expedition through the flat water portion of the Amazon River in Peru. He quickly became an essential part of the team and later guided the 2013 Kayak The Amazon expedition along the same route. Cesar's work helped assure the success of the first expedition to paddle the entire length of the Amazon River from it's most distant source to the sea. I highly recommend Cesar for any expedition.
