Camdenton, Missouri, is home to the turn-of-the-century ruins of the Ha Ha Tonka Castle, dreamt up by Kansas City businessman Robert Snyder in 1905. After he passed away, his sons completed construction of the castle in 1920, but a fire destroyed the property in 1942. The state purchased it in 1970, and it became part of the Ha Ha Tonka State Park. Its once-grandiose ruins remain open to visitors today.

You can visit the castle today for a wine tasting quite unlike any other you’ll find in Napa Valley.
