May I camp anywhere?
There are various things to keep in mind if you are planning to camp or spend the night outside organised campsites. In November 2015, new conservation legislation came into effect making changes to where it is permissible to camp. For instance, it is now illegal to spend the night in tent trailers, tent campers, caravans, camper vans or similar outside organised campsites or urban areas unless the land owner or rightholder has given their permission.
The Environment Agency of Iceland has listed up what to do and not to do when it comes to camping. Visit their website for further information
