Pros: - Nelson was a very friendly and approachable guide. We had great fun with him. On the way to the individual stations he was able to tell us a lot about the region and the jungle (in English and Spanish). - We were lucky to be the only guests on the tour so the price was good for a "private tour". Additional costs for entrance fees were 40 soles per person. - Due to the very humid climate, the length of 6 hours is ideal. So we were free to organize the second half of the day for ourselves. Criticism: The last station (the anaconda's cage) is very sad to watch. It is a kind of zoo in which various jungle animals, including anaconda, are on display and you can "play" with them. The entry of 20 soles should be omitted or an alternative should be offered and not supported in this way of dealing. Saludos, Elias & Jasmin de Alemania
