Fort Smith National Historic Site, Arkansas

See what life was like on the wild outskirts of Indian Territory at Fort Smith. In the 1800s, this outpost saw a stream of ruthless outlaws and rugged lawmen. Today, it's a fascinating park that takes you through the early days of America.

The park's brick barracks have a dark history. Start with the exhibits on the U.S. Marshals. These men hunted desperate criminals throughout the Indian Territory. In the courtroom, see where Judge Isaac C. Parker prosecuted the captured men. In the basement jail—"hell on the border"—you can almost feel the outlaws' presence. Don't miss the reconstructed gallows, a chilling reminder of the 86 men who perished there. Check the calendar for ranger-led tours, or pick up an audio tour.

While you're at Fort Smith, learn about the Trail of Tears. Interpretive signs explain how Native Americans were forced from their homeland and into Indian Territory. Outside, follow the same path as thousands of displaced Choctaw, Chickasaw, Muscogee Creek, and Seminole. An overlook offers views of the river route that the Cherokee people took the west.

Near the park, you'll find campgrounds along the Arkansas River. Whether you're in an RV or tent, there are plenty of comfortable, well-maintained sites.
