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, and dogs must be kept on a leash at the fortress all year. Visitors are not allowed to remove parts of buildings, bricks, stones, timber or other loose objects from the fortress.
The walls of Akershus Fortress are high, and some of them are not secured. Be careful when walking along the fortress walls, and keep a close eye on children.
There are four entrances to Akershus Fortress's inner fortress area. The main gate with the entrance via the bridge from the outer fortress area is the most easily accessible. The area inside the fortress is laid with cobblestones and there are some steep inclines. This combination means that it can be difficult to make your way around in several places. For disabled parking, please contact the fortress police at the main gate in Kirkegata. Otherwise, cars must be parked outside the fortress grounds. Unfortunately, the visitor centre is not accessible without assistance. The toilets in Søndre Brohus are disabled friendly.
The Norwegian Armed Forces Museum and the Norwegian Resistance Museum are disabled friendly inside the buildings. Access to the Norwegian Resistance Museum is up a long hill that may be difficult to negotiate with a wheelchair. The exhibitions at the museums are not especially adapted for people with hearing and visual impairments.
