I did not participate to any tour, I am just hosted for free by Josuel in his home in Manaus.I would like to write how much I am impressed by him, his kindness, his discretion, his calm, his sincerity.He is a really really good person, and, for me, the experience of living with him and his family is, in itself, an unforgettable adventure.I have no time to go in the jungle, but I understand why he gets so much praise in the other reviews.I don't know the other guides, but for sure Josuel is fantastic.If you have the luck to have him as a guide, you will experiment both the experience of the true nice nature, and of a true nice human.
