Bent's Old Fort National Historic Site

In the 1840s the Arkansas River was the border between territory claimed by the United States and Mexico. Located along the river, Bent's Fort was an adobe trading post on the Santa Fe Trail, where traders, trappers, travelers, and the Cheyenne and Arapaho tribes came together in peaceful terms for trade. Today, a reconstructed fort allows visitors to explore the front line of Westward Expansion.
