Angel Falls, Venezuela

Perched almost a kilometre above the jungle floor, the world’s highest waterfall is iconic in every sense. Carved out by millions of years of flowing water, sheer sided mountains dominate this landscape, providing the stage for this geographical phenomenon. While Sir Walter Raleigh’s El Dorado expedition in 1595 is widely cited as the first western expedition to set eyes on the tepuis, more recently their unfathomably big, vertical walls have been the pinnacle of progressive climbing.
