As soon as you cross the border, a Colombian National Police post immediately attracts your attention. Armed officers carrying submachine guns closely observe who enters and leaves the country. Leticia is the capital of the department (state) of Amazonas and the largest Colombian city along the border with Brazil. It is also the export location for a significant portion of the drugs produced in the country, a portion which enters Brazil through Tabatinga.
