Jorge Gudman and his guides are a very experienced team. All of them grew up close to Leticia and for this reason they have a lot of knowledge about the Amazon. They are a registered tour agency, and have organised tours since the 1990s. The tours are very flexible, if you have just a short time, they will organise a special tour for you, so that you can do as many activities in your time available. Also they organise tours to the not so touristic places like Puerto Narino, but more to places like Gamboa and Sacambu, which are indigenous tribes of Peru. You will be part of the local community of the Tikunas (sleeping in their houses, have local guides) and for that reason the agency is supporting the people in the jungle!
Sergio Rojas is one of the most famous travel guides in the Amazon. He can answer any question about your trip and take you to the most exotic places in the Amazon Basin, and he speaks English.
