The first non-federal visitor center certified as an Old Spanish National Historic interpretive facility exists at Fort Uncompahgre in Delta, Colorado. At Fort Uncompahgre you can step back in time and visit the replica of an 1820s era historic fur trading center and learn about the history of the earliest days of commerce on Colorado’s Western Slope including the Old Spanish Trail. Antione Robidoux established the trading outpost in the late 1820s in an area known as Robidoux Bottoms near the junction of the Gunnison and Uncompahgre Rivers. This area was a hub for trails coming north out of the San Juan River Basin in southwestern Colorado and northwestern New Mexico, meeting the North Branch of the Old Spanish Trail.
