my camping list is:
tent
groundsheet
sleeping bag & blanket (or if going by car two double duvets)
towel & tea towel
chair
stove (+ pans & eating stuff)
cup
water container
pen & paper & scissors
first aid kit
torch
string
candles
clothes pegs (for making structures)
small rucksack
bin bags
hand cleaner
toilet roll
ashtray (no point in hotrocking the bottom of your tent it lets all the water in trust me)
but if you're only going for 1 night you probably only need half that (ands if you dont need to cook its less again). of course if you go by car you can take all sorts but sadly i cant drive
