$14/night tent camping. Spent two nights. Thursday night was great. Plenty of site for everybody to spread out. Friday night was much more crowded. Sites are all nice and flat and level for tent camping. Vault toilets are very clean. There is a playground if you have kids. Decent hiking, unfortunately the caves themselves were closed during our stay. Easy access from I-90. Would stay again mid-week or off season, but during prime time I'd prefer a bit more seclusion.
