While Parintins is small and doesn’t have a great deal of infrastructure, it is quite used to handling ship traffic: It's located on an island, separated from the mainland by a channel. In this part of Brazil, the Amazon's mighty flow long ago created an island group, interlaced with many channels, from what was once a single island. As a result, Parintins is reachable by ship, not by car, and the preferred local transportation is boat. That hasn't stopped it from hosting one of Brazil's most theatrical festivals.
