Is there anything more beautiful than a giant, stunning waterfall? Angel Falls -- also known as El Salto Ãngel -- is located in southeastern Venezuela's Canaima National Park and is the tallest waterfall on Earth. It stands at 3,212 feet tall, with water pouring down from a flat-topped plateau called AuyÃ¡n-TepuÃ­ (âDevils Mountainâ in English). Accessing Angel Falls requires a bit of a trek, so it's a site made for adventurers. If you can make it though, it's totally worth it.
