There is something for everyone on this remote river in Utah's high-desert country. Bighorn sheep can be viewed along the river's south side, so remember to bring your binoculars. You can choose to run the upper 26-mile section from Sand Island to Mexican Hat, or the 58-mile section from Mexican Hat to Clay Hills Crossing. Or you can run the total length of 84 miles. You can also start your trip from Montezuma Creek upstream of Sand Island.
