Fall River Pass (elevation 11,796 feet (3,595 m)) is a mountain pass in northern Colorado, in the Rocky Mountains of the western United States. It is located in the Front Range, within Rocky Mountain National Park. The pass is traversed by U.S. Highway 34 on Trail Ridge Road between Granby and Estes Park. However, as at Milner Pass on the Continental Divide, the road does not descend after reaching the pass from the west, but instead continues to climb along a side ridge; thus, neither pass is the high point on Trail Ridge Road, which crests at 12,183 feet (3,713 m) elevation, east of Fall River Pass, still within Rocky Mountain National Park. On the other hand, the old, largely unpaved, and one-way-uphill Fall River Road (see adjoining map) does have its summit at Fall River Pass, where it joins the modern highway for the descent to the west.
