I crossed the entire Amazon rainforest, travelling from Peru to Suriname. In this post I will give you all the details on how to get from Yurimaguas to Iquitos - either with a fast boat (in 24 hours) via Nauta, or with the slow boat in 3 nights, sleeping in hammocks. Incl. what it costs to travel from Yurimaguas to Iquitos, what to do in Yurimaguas, what to do in Iquitos, and how safe I felt as a solo female traveller (safe!).
