Prior to 1993, the island was owned by the Norwegian government and it was used as a naval base and training grounds, but since that time, the municipality of Kristiansand has taken over and is now using it for recreational purposes.
At Bendiksbukta, a dagger, an ax, and other tools of flint dating back to the Stone Age (Around the year 1000 BC) have been found.
The quarantine station was separated from the rest of the island with a high wall that runs from the height of Lasaretthøyden to Bendiksbukta.

Odderøya offers opportunities for recreation, walking in the woods, swimming and fishing from the rocks, despite the proximity to the city.
[30] Haubitz Hall Salongen is a lounge on the top of Odderøya that is used for smaller club concerts, with mostly local artists.
Haubitz Hall Salongen is inspired by American jazz / cabaret clubs of the 1940s, as well as from the house's own history as an officers' booth and later a cinema room for the former boot camp.
