No, unlike many other European countries there is no general ban on wild camping in Sweden. There is however a strict ban against driving with any kind of motor vehicle into the wilderness.

In the English language the term "Wild Camping" usually means spending a night outside of official camp sites. However, in most European countries a clear distinction is made between "Wild Camping" and "Overnight Parking". And what is this difference? A: As long as you simply pull up onto a car park where it is legal to park your van and spend one night there this is Overnight Parking. If you have a drink or dinner before bedtime and take a shower and have breakfast before leaving next morning this is still fully OK. If you put anything outside of your van (like camping furniture), roll out an awning, run a generator, fire up a barbeque or do anything else like that then this is considered as Wild Camping. Usually it is also considered as Wild Camping if you stay on the same spot for more than 24 hours. As a rule of thumb one can say that as long as you could drive off at any time without leaving the vehicle or leaving anything behind, then you are Parking.

You should always keep a low profile and avoid too large gatherings of motorhomes. The maximum number of motorhomes depends of course on the size of the car park, the proximity of inhabited houses (anyway, "Wild Camping" close to houses is a contradiction in terms, isn't it?) and the "sensitivity" of the surroundings. Especially if you are travelling in a group of motorhomes you should seriously consider to only pull up onto camp sites and official motorhome sites.

The "Allemannsrätt" allows you to pitch up your tent on non-cultivated ground under certain conditions. Some of these conditions are: Max. stay 48 hours, no garbage left behind, if closer than 150 metres to a house or cabin you have to ask the owner for permission. There are also other parts of the Allemansrätt about collecting wild berries and mushrooms etc., but they are not discussed here.

Basically yes, however certain National Parks and Nature Protection Areas are meanwhile explicitly exempted from it, here any kind of overnight stay is prohibited. At the entrances to these areas you will find signposts and maps with a clear display of the protected area.

Basically nothing, as it only applies for non-motorized tourists with tents. However it is considered as polite to also ask the owner if you intend to stay within sight of an inhabited house. And of course the restrictions regarding National Parks also apply for motorhomes.

Yes, unless overnight parking restrictions are signposted. In fact on some new lay-bys along recently (re-)built road stretches you even find dedicated motorhome pitches.

Keep in mind that road and especially motorway lay-bys are not always the most pleasant places to stay, because of traffic noise, exhaust fumes etc. And especially some lay-bys along major tourist routes and close to urban areas in the south of Sweden seem to attract certain unpleasant, if not illegal, nocturnal activities. Especially from the E6 in the vicinity of Gothenburg an increasing number of nightly raids on motorhomes has been reported during the last years.

Even though Sweden is still one of the safest countries to travel and the risk can not at all be compared to e.g. motorway lay-bys in southern France, you should better forget about it! In fact illumination seems to help these low-lifes, probably because they do not have to use torches. And the more motorhomes there are the higher is the probability that they find what they are looking for. In addition the ever-present traffic noise covers their activities, and the nearby motorway allows them a quick and easy escape.

Basically yes, but there are two exceptions: If the car park is within the protected area of a National Park then you may not spend the night there. Such car parks do exist, an example is the "Tiveden" National Park. And sometimes you find local signposts that say otherwise. Their legal status is however in some cases questionable, so the decision is up to you whether you "take the risk" or not. In the following answers some of the more frequent "flavours" of these signs are discussed:

Motorhomes may not park here at all, other vehicles may. This is an official traffic sign and should be observed. Otherwise you may be fined.

Motorhomes may not park here during the specified time. Again this is official and should be observed.

You may not place a caravan here. Has no meaning for motorhomes. This sign is usually only placed to prevent a quite common Swedish habit: Placing a caravan at a scenic spot for several weeks if not months during the summer.

You may not pitch a tent here. Has no meaning for motorhomes.

This is a difficult one. You find it usually in the vicinity of camp sites, which already gives you an indication who has placed it... Many of these signs are hand-painted and do not look very official. And as long as you are simply overnight parking, you are strictly speaking not camping! However many of these signs seem to deliberately aim at nightly motorhome stopovers. So it is again up to you to decide whether you stay nonetheless. Legally you are on the safe side, however there have been reports about raging camp site owners trying to chase away motorhomes in the middle of the night.

This is private ground, so you should not park there even at daylight, unless you have the owner's permission.

This means "No Motorhomes" and should be obeyed.

You will not (yet) find many dedicated motorhome stopover sites similar to the German "Stellplatz" or French "Aire" in Sweden. But their number is increasing. Also some city car parks explicitly allow overnight parking, usually via Pay&Display. Ask at the local tourist office or look into this site's database if you need information about sites on specific locations. If there is no official stopover site you could check at local sports grounds. Follow signs to "Idrettsplass". Usually they are located in a little distance to inhabited houses, provide large car parks and are quiet at night, except if there is an event taking place.

Strictly speaking it is not illegal to spend the night there, however it is considered as very rude to stay at such sacred places.

No problem, as long as you have the owner's permission. Some places, especially marinas, meanwhile explicitly allow motorhome stopovers, but then usually charge a fee.

It is not illegal, but may be considered as rude by your involuntary neighbors. But no problem if you ask for permission.

Again this is not illegal, but in Sweden you will almost always find more pleasant surroundings for an overnight stopover.

Other than Norway there are only very few dedicated motorhome sanitary stations in Sweden. However there are many road lay-bys with public toilets, and at most of these toilet building you will find a special basin for emptying portable toilet holding tanks behind the door marked "Latrin". Here you can also dump your grey water into, if you have a portable container for it or use the emptied toilet cassette. For some large motorhomes or RVs this is however not an option because the basin is mounted too high. These have to go to camp sites from time to time where ground sinks are available.

Usually at petrol stations. Look for "Vatten".

You will find dust bins on practically all car parks, picnic sites etc. Keep in mind that for bottles and drink cans a refund system is in place, so do not throw them in the dust bins but bring them back to the shops and collect the deposit.
