Aerial views: Botswana's Nxai Pan National Park is so remote, a huge zebra migration that takes place each year here wasn't even documented 10 years ago. Today, it's easily reached by helicopter.

Zebra crossing: About 20,000 Burchell's zebras are believed to make their way across 500 kilometers as part of the annual migration. That would make it the longest mammal migration in Africa.

On the trail: African Bush Camps guide Kenneth Mungomba (left), and the company's founder, Beks Ndlovu, are experts at tracking the wildlife of Botswana's Nxai Pan National Park.

Luxury under canvas: The seasonal Migrations Expeditions camp offers a feeling of real adventure, with just six guest tents under the shade of umbrella thorn acacia trees.

Across the savannah: Mungomba drives safary guest across a savannah landscape sapped of all moisture ahead of seasonal rains. Along the way, Kangaroo-like Springhares, cute bat-eared foxes, regal gemsbok and tough Kalahari lions are all encountered.

Tree line: These giant Baobabs trees have changed little in the 160 years since English explorer-artist Thomas Baines famously painted them.

Black and white: "The distance covered by the zebra was a total shock to all of us involved," Robin Naidoo, a senior conservation scientist at World Wildlife Fund, said at the time. "Nobody knew that something of this scale was occurring."
