Littering and other thoughtless behaviour can easily spoil the appearance of the fortress, so please use the litter bins that have been provided. There is a year-round prohibition on fires and barbecues. Visitors are not allowed to remove parts of buildings, bricks, stones, timber or other loose objects from the fortress. Digging and searches using metal detectors are not permitted.
At the marina, please show consideration for your neighbours – and remember that adults are responsible for children's safety.
Oscarsborg Fortress is a fortress with many high walls and quays along the shore. Some of the walls are not secured. Be careful when walking along the fortress walls, and keep a close eye on children. There can be strong currents in the sea, so keep an eye on small children when they are bathing.
The fortress is not especially adapted for disabled people, but work has started on finding good solutions for universal design. Oscarsborg Fortress is situated on two islands, Nordre and Søndre Kaholmen, and you can get there by ferry. It is no problem getting wheelchairs on board the ferry. The roads on the islands are partly gravel roads and partly tarmac roads. There are steep sections in some areas, but there are also alternative paths to the most important attractions.
The Fortress Museum in the main fortress and the restaurants and cafés have lifts/arrangements for wheelchairs. There is also a separate building with a disabled toilet.
