Hope I can help a little since we live in CO. Not many gym camps---certainly nothing on the scale of Woodward, IGC etc. Many kids go out of state if they want to do a camp.
CATS(Boulder)--went to a meet there, small gym right near CU campus. If they use the CU facilities, might be worth checking out. Gym is not one of the major competitive programs in the state and I don't know anyone that has attended their camp.
Colorado Aerials(C. Springs)--Have never had a camp. Have a nice big gym with alot of room to host a camp, but they have never gone that direction. Their website is very dated and you may just want to call to see if this year might be different.
University of Denver--Looked into this one last year. 3 days/4 nights for 500+. We had a meet at the Ritchie Center(gym, pool and 2 skating rinks)--nice facility. Girls stay in the dorms. Not much info about what they planned in "free time." Staff is primarily coaches for the women's team and a few team girls. They might have some info up now on their website.
Stars National Gymnastic Village(C. Springs) Seem to be trying to develop a 1 week camp to fill a void in the state. Called Rocky Mt. Training Camp. Option of commuter or overnight. They will have guest coaches for some events and some folks from the Olympic Training Center to talk about nutrition, sports psychology etc. Don't know about the "free time" activities.
Hope all this helps. Let me know if you need more info
