Boat schedules on the Amazon are highly erratic, except the luxury cruises. Here's a site for Leticia that mentions the fast ferry to Iquitos, and suggests you contact them for updated information. Keep in mind that the three frontiers of Peru, Colombia and Brazil join here, so any ferries will generally call at all three port, Santa Rosa, Peru; Leticia, Colombia and Tabatinga, Brazil. Leticia is by far the largest of the three, and you will get most of your information from there.
http://www.visitleticia.com/main/?page_id=4If you want to come from Peru, you can use the Fast Boat service between Iquitos and Santa Rosa, Peru, located across the river from Leticia / Tabatinga. The trip is 10 to 12 hours, departing every day at 04:00a.m. except Mondays.
NOTE: As requirements you should bring your passport and international yellow fever vaccination card.
NOTE2: FOR US CITIZENS a tourist visit is required to enter Brazilian territory.
NOTE3: Please check with us first before making any reservation, because the airplane and the boat schedule change from time to time.
