Theodore Roosevelt National Park, tucked into the rugged badlands of western North Dakota is where a young Theodore Roosevelt came to recover after the loss of his wife and mother in the same day. He bought a ranch, rode the open plains, and found the resolve that would later define his presidency. Today, the park named in his honor preserves that same wild spirit. Visitors can still see Roosevelt’s original Maltese Cross Cabin near the park's entrance and walk trails he once rode on horseback.
