 Get in
Movement between all three countries' border towns is unrestricted; but of course, make sure you're stamped into the correct country if leaving the border area. Try to minimize the amount of times you go through immigration: i.e. if entering the region from one country and leaving from another, just get one exit and one entry stamp - even if you visit all three towns in this area. Anything more seems to annoy the immigration officers.
The Colombian immigration office is at the airport, so if you're flying in and moving on to a different country you may as well get an exit stamp when you land. Don't wait several days between getting your exit stamp and the next entry stamp; however leaving it one day doesn't cause any problems.
The Brazilian immigration office is located some way down Tabatinga's main avenue, Avenida da Amizade. The Peruvian immigration office in Santa Rosa is fairly central and easy to find, just ask someone.
 By plane
You can only get into this spectacular, tropical and adventurous town from Colombia by plane or boat. The only place connected to Leticia by a commercial airline is Bogota, there are daily flights with companies Aerorepublica (now Copa), Aires and Satena. The flight lasts two hours.
On arrival to Leticia, non-Colombian citizens are directed to a different entry door to the airport, and the police will ask them for name, nationality and signature. In addition, non-Colombian tourist have to pay an entrance fee (Impuesto al turismo). The fee paper is colorful and it may seem that the representative is trying to sell you something if you don't understand Spanish. None of the officials may be able to speak English. Entrance fee was COP19000 in April 2012 and it's valid for one year.
 By boat
 Get around
Mototaxis abound. It should be about 1000 COP from the center to the border with Brazil, more if you're going to the port. There are also motocarros, covered tricycle-type vehicles in which you're more protected from the elements. You can rent a moto or a bicycle in various points around town.
