Welcome to Pororoca, one of the longest waves in the world. The tidal bore travels up to 500 miles (804 kilometers) upstream of the Amazon River in northern Brazil.
It's an impressive natural phenomenon that forever remains in the memory of those who see it and ride it.
The word Pororoca should come from the indigenous Tupi word "porórka," meaning "great roar," or from the aboriginal term to express the act of destroying everything.
Brazil is one of Nature's sanctuaries on Earth, home to rich fauna and flora and the epicenter of nearly all natural events.
French oceanographer and filmmaker Jacques Cousteau was the first person to document Pororoca aboard his RV Calypso research vessel on March 28, 1982.
