Ok let me think....
Most important stuff to bring:
* 2 rolls of toilet paper in water tight bag (trust me there is never enough toiletpaper when going to camp)
* flashlight + extra batteries
* compass (when she is getting dropped off somewhere in the middle of the night. She really want to orientate where she is going, she has to keep the * compass hidden though

)
water shoes, in case they are going to swim in natural swimmingarea's.
* bathingsuit (one piece!!! a two piece bathingsuit isnt suitable for scouts camp, trust me.)
* toothpaste + toothbrush
* cup, plate and utensils (all plastic, lightweight)
* a good sleepingbag which can be used when its freezing. Trust me it can be cold out there.
* a thermo matrress (one that you can roll up if you want) to put under the normal inflatable matress.
* favorite stuffed toy to sleep with (even if she is 13 already, she will miss home, so a favorite teddy bear or something like that will help, and trust me, more kids will bring theirs)
* comfy shoes to wear when its night and she needs to go to the lavatory, like
crocs.
* Shoes to walk miles with. Preferably closed shoes.
* really thick socks to go into the shoes. To prevent the feet from moving in the shoes, to prevent blisters.
* small portable first-aid kit for hikers.
* anti mosquito stuff (deet)
* tick remover
* sun block
* after sun
* fresh undies (one for every day + 2 extra in case of some serious case of mudwrestling)
* enough clothes for the whole camp + 2 extra sets (make sure most of them are long trousers because you dont want her to hurt her leg while walking past some stingy plants).
If I remember more, ill let you know.
