In the western part of Canaima National Park, is the Auyantepuy, one of the largest and better known "tepuy" (A flat top mountain ending with vertical walls). From this tepuy is where the Angel falls are formed. The fall is 979 meters high (around 3000 ft.), and is the higher waterfall in the world.
There are two ways to see the Angel Falls. One of them is from the air in an small airplane. The other one is an excursion that starts with a 3 hour and a half navigation upstream the Carrao River, and then the Churun river. From there, a one hour walk through the jungle takes you to the base of the falls.
