It’s hard to top the thrill of hovering above the longest mammal migration on the planet. And no, this is not the Serengeti. This is Botswana – uncrowded, greened by the rains, where thousands of zebra trace ancestral routes to vast salt pans sheathed in glassy waters under blue skies filled with migrant birds. If you don’t mind intermittent afternoon showers, you’ll be rewarded with thundering hooves, immense shimmering savannas, significant predator activity and low-season pricing. Come to clear your head in an uncommon landscape, scouting for desert-adapted wildlife. Then complete the circuit exploring the Okavango Delta by Land Cruiser, mokoro, or on foot.
