Victoria Falls, Zimbabwe/Zambia
Victoria Falls (also known as Mosi-oa-Tunya, “The Smoke That Thunders”) are on the border between Zimbabwe and Zambia where the Zambezi River pours over colossal cliffs shrouded in emerald foliage and into a misty canyon. The river winds across the savannah through tall grasses and among small islands, and in the wet season the torrent has a combined width of 5,604 feet (1,708 meters) and falls 354 feet (108 meters)—twice the height of Niagara Falls. If you’re lucky, you can even see a “moonbow” shimmering in the spray at the full moon. The majestic canyon and the almighty roar of the falls are one of the greatest sights in the world.
Iguazu Falls, Argentina/Brazil
The Iguazu Falls are the largest series of cataracts in the world: 275 distinct waterfalls separated by dozens of rocky promontories and stubborn islands. The flood of frothing water tumbles down the rocks and then plunges into the “Devil’s Throat.” The gorge separates the Upper Iguazu and the Lower Iguazu, and the falls form part of the border between Argentina and Brazil. There is a stunning walkway that leads out towards the falls and provides a view of the rushing water on three sides and lush vegetation draped with mist.
