Lovely part of the world, a bit nippy in the winter and has very warm summers, as in the UK there is a risk of forest fires. Wild camping is common but I have no idea if it is legal or not. Carrying of knives and axes may not be legal either but out of towns and in the woods most folk seem to carry something on their belts.
Did you have an area in mind? What time of year?
The people are for the most part very friendly, only young people in towns will speak English, the food is excellent.
You'll have a grand time.
