It is the capital of the state of Amazonas, Colombia’s southernmost town (4.09° south 69.57° west) as well as its only major port on the river. It has an elevation of 96 meters above the sea-level and an average temperature of 27 centigrade (80.6°F).

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.
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.
