Nkasa Rupara National Park, Wetland national park in East Caprivi, Namibia

Nkasa Rupara is a national park in the Zambezi Region made up of extensive reed beds, lagoons, and termite mound islands nestled between two rivers. The landscape is constantly shaped by seasonal flooding, which regularly changes the paths and water holes.

Mamili National Park was proclaimed on 1 March 1990 together with nearby Mudumu National Park. Its former name referred to a family of traditional leaders of the Mafwe tribe. In 2012 the Namibian government renamed it Nkasa Rupara, after two Kwando River islands within the park.

The name Mamili, used until 2012, came from a family of traditional leaders of the Mafwe tribe bearing that surname. The park's northern border adjoins the Wuparo Conservancy, which runs a community campsite outside the park and partners with the Nkasa Lupala tented lodge built under a government tourism concession.

A visit requires a four-wheel-drive vehicle with recovery equipment, as flooding regularly makes trails impassable. Early morning drives are best for viewing wildlife and navigating safely through changing water conditions.

The park's roughly 1,000 buffalo form Namibia's largest concentration of the species. The unfenced park also serves as a corridor for elephant, buffalo, roan and sable antelope moving between Botswana, Angola and Zambia within the Kavango Zambezi Transfrontier Conservation Area.
