Described as 'the river which never finds the sea', the Okavango disappears into a 15,000 sq km (5850 sq mi) maze of lagoons, channels and islands in north-western Botswana. It's the largest inland delta in the world, and it teems with wildlife.
Most obvious are the birds - thousands upon thousands of them - but there are also elephant, zebra, buffalo, wildebeest, giraffe, hippo and kudu. In the centre of the delta, the Moremi Wildlife Reserve totals around 3000 sq km (1170 sq mi) and is officially cordoned off for wildlife preservation.
About 60km (40mi) southeast of Moremi, Maun is the administrative centre of the delta and home to the main airstrip. The cheapest area to visit is the Eastern Delta, as there aren't as many controls on operators here, and most of the guides and boat pilots are unlicensed freelancers.
