The tri-frontier region is open territory you do not need a visa to Brazil as long as your next destination is not a town or city in Brazil. Technically you will go from Leticia (Colombian territory) to Tabatinga (Brazilian territory) to go to the wharf to board a water taxi to Santa Rosa island (Peruvian territory) to board the speed boat. People travel in those territories at will without hindrance.

The hotel in Leticia has the speed boat information.

I am inclined to disagree with yaofeng this time

If you are found in Tabatinga without a visa for Brazil then you risk being deported and having this recorded in your passport. It is a tiny risk but still a risk. So far as I know there is no provision for being in Tabatinga without a visa on the basis that you are going somewhere else

You dont need a visa having your passport stamped in Colombia, given Tabatinga is a border town. But you can not leave Tabatinga into Brazil without a visa.

You don't even have to visit Tabatinga. You can take the fast boat to Iquitos (every day but Mondays) in Caballococha, Peru, 100 kms upriver from Leticia. The fast boats' company has a hotel there. There are regular boats from Leticia to Caballococha every day at 2 pm.

The migration process is done in Leticia's airport and in Santa Rosa, Peru.

There is no Peruvian immigartion officer at the Leticia Airport I don't think as it is a Colombian territory. So you'll have to pay your entry fee into Amazonas and exit fee out of Colombia at the same time when you land at the Leticia Airport I presume. And you have to somehow get to Santa Rosa Island to enter Peru. Unless you can officially enter Peru upon arrival at Iquitos bypassing the visit to Santa Rosa Island.

The tri-frontier region is open border when we visited in 2008. I think Borugo confirmed it is still the case. There is a street going straight from Leticia to Tabatinga where people go back and forth at will. The police at the border knows better to not stop anyone to check papers as first he will be overwhelmed and second no one carries any except tourists which are few and far between. We stayed in Tabatinga and went back to Leticia to get money from the ATM as the ones in Tabatinga would not accept our debit card. Either there was no police there in the evening or he did not bother to stop us (or anyone else for that matter). We simply did not pay attention to it and swished through in our taxi.
