About Okavango Delta

The Okavango's flood arrives in the dry season, filling channels, lagoons and reed islands that teem with elephants, hippos and wild dogs. Safaris run by mokoro canoe, boat and 4x4, with camps on the delta's islands and the Moremi reserve around them. June to September is the flood and high season; the green season brings calving herds, birds and lower prices.
