Victoria Falls
At the border between Zambia and Zimbabwe, the Zambezi River reaches the edge of one world and plummets 350 feet into another. The rainy season lasts from late November to early April, and when the river floods, up to 300,000 gallons of water cascade over the edge every second, creating towering clouds of spray and mist above the Batoka Gorge that can be seen for miles.
