The Colorado River near Moab, Utah, is a journey through whitewater, red rock, and blue mountains--a prismatic panorama that only the American West can create. Towering cliffs, monumental rock towers, snow-capped peaks, and desert vistas characterize this iconic landscape, and the river's swift water is an exciting avenue to tour it all. It makes a great beginner- to intermediate-level run with options for half day, full day, or overnight trips.
