Does anyone know how to cross from Peru to Brazil through Amazon? I've seen some possibilities of crossing from Iquitos to Tabatinga, but are there other options? My final destination is Manaus.
Peru to Brazil land border
A few years ago, we took a boat trip up the Amazon from Manaus to Tabatinga and then we took a cab to cross into Leticia (the Colombian side of the same city - we had to go back to passport control the next day to make it official) since we were flying out of Bogota. It might be possible to get to Tabatinga from Iquitos but even that looks like a pretty remote route. The whole border between Brazil and Peru seems even more remote but, north-east of Cusco, there is good paved road from Peru to Brazil through
Puerto Maldonado, Iberia, the border at Inapari and then on to Rio Branco and Porto Velho to Manaus.

There used to be a boat between Iquitos and Leticia (chose fast or slow). I haven't done it but met a French couple in Iquitos who came in from Leticia and had to return home via Leticia (their flights were from Columbia). That was 2018.
Getting in and out of Iquitos is either fly or river - so OP going via Iquitos might be a slow or expensive route.

Before Corona (2020) ships where running from Santa Rosa (next to Leticia and Tabatinga, no border formalities in this area, but you need the proper stamps in your passport when you leave this area) to Iquitos, and from there (cargo ships) to Pucallpa (buses and cheap planes to Lima) and Yurimaguas (buses to Chachapoyas or Tarapoto and on to Lima). In march 2022 all Peruvian borders except airports where closed, don't know if this has changed. If the border is open at least the cargo boats should be running (rather uncomfortable but more interresting). Was in Peru at far as Chayapoyas march 2022, in the Brasilian Amazonas area january 2020, had crossed from Tabatinga to Letitia a long time ago, had to change my plan to go go by boat to Pucallpa because of a Cholera outbreak in Peru.
