check out the Colorado springs/ pike's peak area. tons of stuff to do for all age groups. Mueller state park (south of divide) is a better campground than Cheyenne mtn (more trees)and very nice. you would have to check and see what's available for site availability.
we didn't care for it and won't be back
1. too much noise (dump trucks from the quarry one after another, etc)
2. no shade to speak (not like camping in the woods at all)
3. too many golf carts speeding around continually
