Hi Eric

I am not sure what you hope to have as your end result, but I would suggest the following:

Get a "crawl tube" (that young children play with)and cover it with gray paper, with "rocks" painted on. This can be the entrance.

Next, get some painters tarps or canvases, the more gray color the better. Paint on the tarps so that they look like the walls of a cave.

Once the tarps are dry, hang then from the ceiling in such a way as to form the walls of the cave. (think tent or canopy) Use dark paper that you have crinkled up and put it on top to look like a cave ceiling.

You will have to figure out how big your cave needs to be based on the number of children that need to be in the cave at any one time.

And if the crawl tube is not workable, maybe you can cover the door of the room with dark paper that has been painted to look like a hillside, with the mouth of the cave painted on it? Cut a flap so that the children can enter by stooping or crawling. (and make sure your adult leaders can also get in!) If you have any children with physical disabilities, you will need to take that into account as well.

Anyway, when you get your cave made, post photos!
