"Wonderful experience sailing the Rio Negro in a river boat, with everything you need to be comfortable and respect the Amazon ecosystem. We did the 5-day tour and although it may seem like a lot, it is worth it just to get to the Anavilhanas Islands. Navigation and overnight on the islands was incredible. Miguel (who organizes the trip) has extensive knowledge of the area and proposes activities to get to know the environment in depth, both fauna and flora, as well as the different communities that inhabit it. We saw numerous animals, many more than expected (multitude of birds, piranha fishing, sighting of pink dolphins, sloths, monkeys, crocodiles and even several snakes), although obviously that depends on luck or chance, since the animals are in its natural environment. The treatment with Miguel and the rest of the team was excellent and we ate wonderfully! Thank you very much for the experience!"
