The bungalow at Eco is bigger and because single is more private. Tambo has had a newer face lift but not private because of no ceiling. I had a young couple next door who used to shower together and when they went to the toilet I knew exactly what they were doing. Eco has a cocktail bar and seems to have more atmosphere. Tambo has a limited bar with only basic drinks. The food is better at Tambo, not bad at Eco, just better at Tambo. Eco has one program of 3 days, 4 days or 5 days where Tambo has a confusing array of 4 or 5 tours with about 4 different levels of service. I have since been on Tambo website and dont know what program I did. If you go there you need to be sure of what you are booking. Eco I was put in a group and stayed in that group which was good cos it allowed me to conect with others in the group and made for a shared experience. At Tambo I was switched around between groups and seemed a like an intruder. In fairness, the weather was perfect at Eco so they got to finish all their programs and made for a better experience. At Tambo the one day I went on a programe it was rained out but there was no alternative and the little we did was not good. The way they handled changing me to another programe was poor to say the least. If you want to see macaws on a clay lick you have to go up the Tambopata, other lodges in the area also do this. At Eco you will see monkeys and caiman, they are almost tame and the guides feed them to ensure it. Both are very sanitised trips into the ´jungle´, really second grade forest. Eco is closer to the real thing than Tambo. Ecoamazonia 8/10 Libertador 3/10 Based on my time at both, I loved Eco and Tambo left a bad taste.
