Pencils & coloring books, a ball & your camera, fishing rods.

Honestly we take very little in the way of activities for the kids, we go on walks, we take them fishing, we setup a little table for them to color in.
They enjoy helping collect fire wood, looking for bugs & lizards.

Water wise we go for about a week so we take quite a few big tubs but DP's uncle also freezes some of the water big fridge water bottles you get in safeway for us and brings them down to camp.

Good quality bin bags and if possible a plastic bin with tight lid, nothing worse than finding wildlife rumaging through your scraps.

I'm sure there is morie i'm not thinking of.
