To be comfortablr you want a foam pad for the ground. If no tent or hammock you want a tarp for the ground too. You want a sleeping bag, quilt or blanket.
You can have a tent or tarp to put up and shelter you from rain. I'd bring one. Being soaked sucks even more than just crashing in some meadow and finiding you're full of dew in the morning.
You want a flashlight but your phone might do.
Bring toilet paper or wipes of some sort.
Bring drinking water, 2 liters maybe.
I recommend you have sleep clothes and a pair of sandals for camp.
Bring strong insect reppelent that you can apply on your skin.
That really is about it there's not much to do. Ofc if you want to eat every day bring a sandwich, if you want to read bring a book, wear appropiate clothes and shoes.
You dont NEED meme shit to sleep outside, like fire, cooking, knives, guns, maps, fompasses, survival mental illness and what not. Not in france.
