We're Sleepy Dragon Campground, and we're a premier campground in Rio, WI. We offer full hookup sites, tent sites, trailer rentals, a dump station, showers, a swimming pool, a playground, a game room, and much more. Our goal is to provide our guests with a relaxing and enjoyable experience while they enjoy the great outdoors. We're looking forward to partnering with Columbia, Marquette, and Green Lake counties to continue to offer a premier camping experience. We'd like to personally invite you to stop by to view our many amenities, today!
