The good: The lodge is very well maintained, rooms are nice, 24/7 electricity, warm shower (only at night?). Wifi for 10USD per device for your entire stay. Trails are easy to follow. Food is pretty good, mostly western style. Owner was very helpful with arranging transport and manager Stefano is polite and nice. The lesser part: Our guide Diego did not gave us a welcome feeling. At arrival nobody came to us to explain anything, so we just joined some other tourist at a table for lunch. Later Diego came to say hello and explain some basics, but the only info about the activities was “a long walk after breakfast” for instance, and we constantly had to ask what to wear and bring. 
During the activities Diego does not explain much, but we mostly need to be silent. Some info is incorrect (for instance about snakes/venom). We saw some pretty unique animals and Diego does have a lot of knowledge about the area and history. 
I would recommend the lodge, even though it’s not a cheap option, but the guide you get really can make a difference in how you experience this area.

Amazing immersion into the jungle of Yarina and the Napo river. Olivio was a wonderful guide, food was great, and each excursion was filled with innumerable wildlife sightings, learning about the jungle lifestyle and ecosystem, and plenty of time for independent exploration. Transfers and coordination of events were seamless and easy. Highly recommend.

Yarina Ecolodge went above and beyond! We had an amazing time! The rooms are spotlessly clean and very comfortable. The staff were friendly and kind. The food was amazing, exceeding all our expectations. The mosquitos were not too bad. And best of all, our guide Livio was knowledable and above-all enthusiastic. We loved how excited he got about a special bird or monkeys. He also taught us so much about the jungle, the fruits and jungle medicine! Special excursions to visit a local family and to Laguna de Limoncocha were unexpected highlights.
