The Mississippi River, a dividing line as physical as it is symbolic between the East and the West, originates in northern Minnesota before flowing, 3,734 kilometres (2,320 miles) further south, into the Gulf of Mexico. Like a real natural artery crossing the United States, its captivating aura makes as much of an impression as its length. There are exceptional flora and fauna to be found along the riverside, with no less than 260 species of fish, around fifty mammals and over 150 species of amphibians and reptiles. During this cruise, you will perhaps be lucky enough to spot the mythical Mississippi alligator, the captivating yellow turtle or even the sweet river otter.
