In principle, everything is permitted that does not lead to permanent changes on the property. So you can visit the country, have a picnic, read a book and in the evening spend the night in a tent on your own property. We all want the property to remain in its natural state - to the great delight of people, animals and plants. Things that change the property permanently, such as building a house, cutting down trees, growing wine, garbage disposal or free campfires are not allowed.
