Moremi Game Reserve, Botswana
Closest major city: Maun, Botswana (93 miles)
The Moremi Game Reserve, on Botswana’s Okavango Delta, is a 1,900-square-mile basin of swamps and woodlands teeming with wildlife. It’s an ideal spot to listen to the songs of the birds perched in the acacia trees and wading in the reed beds along the rivers; the cackling of hyenas; and, if you’re lucky, even the quiet, padding steps of a leopard. Peak travel season is July through October, when the animals gather near the water and are most active.
