When the calm flowing waters of the Zambezi River encounter the 1700-meter (1-mile) wide edge of the Victoria Falls gorge on the Zambia-Zimbabwe border, they abruptly plunge 100 meters (330 feet) to the bottom. The impact generates soaring mists and thunderous sounds that I could see and hear from great distances.
Worst times
Mid-December to mid-April
This is the rainy season. The rising mist can become so thick that you see little. And the excessive moisture could damage your camera.
October and November
Because this is the end of the dry season, the falling water can slow to a trickle along most of the the rim.
Best time
Mid-May to mid-September
The falls are strong and the visibility-obscuring mist is gone.
