Boa Vista is the capital of the state of Roraima in the north of Brazil. Most foreigners pass through en route between Manaus and Venezuela.
Manaus is a Brazilian city of about 2.5 million, located on the Rio Negro a few miles before it meets the Rio Solimões to form the Amazon River proper. The two rivers flow side by side for many miles, different in color, mixing in eddies.
Think of the Amazon River and visions of wild jungle, exotic animals and native peoples come to mind, sailing on the Amazon River is an incomparable experience. Manaus in the Amazonas state is 1107 KM away from Leticia and the only transportation available are by boat (5 days) or plane.
