Walvis Bay, with its large bay and sand dunes, is an important centre of tourism activity in Namibia. Attractions include the artificial Bird Island, centre of a guano collection industry, the Dune 7 sand dune, the salt works, the abundant birdlife, and a museum. Kuisebmund Stadium, home to two clubs in the Namibia Premier League, is also located in the city. The beach resort of Langstrand lies just a few kilometres north. The Walvis Bay Export Processing Zone is an important facet of the local economy.
