"The City Museum is a one-of-a-kind experience for adults and children alike!. With four floors of interactive exhibits, tunnels and slides, an outdoor climbing space, an architecture museum, and a cave system to explore, there's plenty to keep everyone occupied all day. If you hit a mid-day slump, head over to the on-site historic Cabin Inn where those over 21 can enjoy a refreshing cocktail or craft brew while the little ones devour a hand-scooped ice cream cone."
