Mount Roraima, Venezuela, Brazil, Guyana
Mount Roraima is a massive plateau with sheer 1,300 foot cliffs on all sides.

Many plant and animal species on the plateau don’t exist anywhere else in the world.
Caño Cristales, Colombia
Best viewed during June and November, this rainbow river in Serranía de la Macarena National Park in Colombia owes its seasonal color bursts to aquatic plants that thrive only when the water level is neither too high (which obscures the plants) nor too low (when it’s too dry for them to grow). Tourism is a threat to the delicate environment, and visitors are asked not to swim if they are wearing sunscreen or bug repellent.
