Tourism
Several tourist attractions in this district have been widely explored and visited by a variety of local and foreign tourists, but there are only a few who have access to roads and adequate facilities and infrastructure available, namely Mananga Aba Beach, Mbawana beach, Oro Beach, Kawona Beach, Newa Beach, Pantai Waikelo, Sumba Cultural Home, Lake Saltwater Weekuri, and Pabeti Waterfall.
This district includes several traditional villages such as Wainyapu and on the south-west coast, and others inland. Wainyapu is particularly rich in dolmens, which - as of 2021 - are still built for collective graves.
