Littering and unintentional destruction can degrade the fortress. Use the litter bins that have been provided. There is a year-round prohibition on fires and barbecues, and animals must be kept on a leash at the fortress at all times of the year. Visitors are not allowed to remove parts of buildings, bricks, timber or other loose objects from the fortress.
Fredriksten Fortress is a fortress with high walls, some of which are not secured. Be careful when walking along the fortress walls, and keep a close eye on children.
The easiest way of getting to Fredriksten is by private car, and there is good parking. The outer part of the fortress is relatively flat, but the main part of the built-up area is so steep that it is practically impossible to get around by wheelchair (there is an altitude difference of almost 100 metres between the upper and lower parts of the fortress).
There is a Tourist Information Office just inside the entrance, where you can experience a multi-media presentation about the history of the fortress. The museums are not adapted for wheelchairs with stairways and exhibitions over several floors, and no lift.
