Camping is officially only allowed in campsites. In practice camping is tolerated in a lot of places (generally outside of the localities) but use discretion and sensitivity. There are occasional crack downs on unauthorized campers once in a while (usually when there are too many of them) but you are unlikely to get into trouble for breaking the law if you accept to move elsewhere.
are only a few official campsites. Most are very simple, with lots
of nature and little comfort.
There will be a tavern and a bar nearby, occasionally a swimming-pool.
Most camping sites are situated very close to the sea.
Many camping sites will also allow you to sleep there without tent.
