The Okavango Delta is a unique oasis: a vast inland wetland that floods during the dry season, providing water in the arid Kalahari when it's needed most. It's one of the 7 Natural Wonders of Africa, as well as a UNESCO World Heritage Site. Remote and inaccessible by road, it's still an almost untouched wilderness, a refuge for incredible concentrations of birds and wild animals. Most of the large mammals in the delta are seasonal residents, arriving in the dry winter as the miraculous floodwaters start to surge in from Angola, and departing again in spring when the rains come.

 

Most visitors to the delta arrive and travel between lodges by small planes, providing a tantalising introduction to the wonders that await. Game-viewing opportunities in the delta usually include mokoro canoe rides, boat cruises, game drives and walking safaris. But, taking a scenic flight over the delta - whether by plane, helicopter or hot air balloon - is undoubtedly one of the most spectacular ways to see Africa's Eden.
