Right to access
Right to access
Allthough Norway is quite expensive, many of the things that are of most value is free-for-all -- the scenery, hiking, quite a lot of museums and many other sights.
Not only that, for those who feel like camping, it is generally possible to camp freely in the woods and in the mountains. This is thanks to regulations of the Outdoor Recreation Act, which grants a right to walk and stay overnight on anyone's land, provided you're out of the way. This is known as Every Man's Right (allemannsretten).
Given knowledge of this law, it is in fact possible to travel rather inexpensively in Norway.
Obviously a law that comes with such a right also comes with responsibilities and some limitations.
Walking and passing
It grants access to walk across uncultivated lands. That means you can walk if there isn't farmlands or across people's gardens. If there are fences, you should look for gates and follow paths, also in the case that there is no apparent farmland (there might be animals, such as sheep or cattle in the area, so close any gates you open). Also, if there are newly planted trees in an area, you can't walk through.
Other than that, you can pretty much go whereever you like.
Camping and picknicking
As for camping, you can stay for up to two nights in one spot, as long as you are far away from any houses and farmlands. 'Far away' usually means 150 meters. However, it also means out of the way, that is, you're not inconviencing anyone and particularily not those in the nearest house.
These regulations obviously don't go for those areas especially designated for camping, but those are usually paid campsites.
If 'out of the way' sounds hard, it really isn't. There is a lot of free space in Norway...
In really remote areas, the two-day rule doesn't even apply, and why should it, nobody will notice you're there anyway....
Pretty much the same rules apply to picknicking.
Leave no trace
Whatever you do and whereever you go, it is still your responsibility to leave no trace behind. That means, leave no garbage behind, make sure the camp site you used looks as good when you leave it as when you came. Do not break off any trees. This is the responsiblity you get in exchange for the right to access.
Text of the law
The full text of the law can be found on the Ministry of the Environment's website.
Along many popular tourist roads and spots, there are "no camping" signs. These are there to avoid a heavy impact on particulary popular areas, and so should be respected. Just go a few hundred meters further, make sure you're out of the way, and you're OK.
Allthough camping vans are OK, it is generally but usually silently frowned upon just parking them in a parking area and stay overnight. Obviously one tries to pave as little as possible in the mountains, and so, parking areas are deliberately a scarce resource, and should be used only for parking, not for camping. If you're using a camping van, use paid campsites.
