Riding One of the Longest Waves on Earth | Forces of Nature | BBC Earth Science

Every surfer knows the importance of catching the perfect wave - but what if that wave went on for miles against the current, sometimes with entire trees caught up as debris in its wake?
The Pororoca is a tidal bore, traveling up to 500 miles upstream as the direction of the Amazon’s current is reversed by high ocean tide in the Atlantic.

These river waves do look a bit more boring to surf, but I bet there are so many animals there trying to eat you alive that it makes it just as exciting.
