Leticia is a little city that becomes the border between Colombia,Brasil and Peru. Leticia and Tabatinga are realy just one city divided in twoo sides, the Colombian and the Brasilian. You can cross it by walking. That's the place for the contraband, ilegal bussiness and local mafias, and that's why is so interesting and exciting. Is not that bad, there are also friendly people and places to have fun, that's the starting place to a more real amazon jungle experience. Out of the tourist crowds you will feel here as the only foreigner and the jungle expeditions are more excepcional from here. There's nothing really interesting in the city. If you want to have fun you have to go to the Brasilian side, Tabatinga, but the cheapest place to stay is the Colombian side, Leticia. There is a Zoological park to see some of the animal species of the area. (They have the biggest Anaconda that i ever seen!!) Is also interesting see the people at the little harbour negotiating the prices for the fishes that they bing from the Amazones river.
