Slow boats between Manaus and Tefé (hammock R$175, double cabin R$650, 36 hours) depart in both directions five to seven days per week. Boats to and from Tabatinga (R$195, 40 to 48 hours) don’t dock in Tefé proper; instead, take a boat to the village of Nogueira and taxi from there to Alvarães. Do the reverse if arriving from Tabatinga, but be aware that taxis and boats are available only during the daytime.
AJATO has comfortable speedboat service to and from Manaus (R$270, 13 hours), with departures a few times per week at around 6am, and to and from Tabatinga ($460, 23 to 24 hours), with four departures weekly.
Advance reservations are recommended, especially for speed boats.
