McInnis Canyons NCA is located on the flank of the Uncompahgre Plateau, which rises like a giant, rolling wave over the Grand Valley in western Colorado. Rugged canyons descend to the Colorado River and contain some of the most spectacular landforms found anywhere in the country, including Rattlesnake Canyon, Dinosaur Hill, Devils Canyon and Mee Canyon.
Internationally important fossils have been uncovered here during more than a century of excavation. Pictograph and petroglyph sites abound, and the Old Spanish Trail, once referred to as the “longest, crookedest, most arduous mule route in the history of America,” runs through the NCA. Today, the NCA is a recreation destination, drawing visitors to the world-class mountain biking on Mack Ridge and along the 142-mile Kokopelli trail, which extends to Moab, Utah. Twenty-five miles of the Colorado River wind their way through the NCA, attracting boaters who value straightforward floating through spectacular multi-hued sandstone canyons.
