Nearly 100 years old and never more than 14 feet wide, this road stretches for 11 miles, from the park's east side to the Fall River Pass (11,796 feet above sea level) on the west. The drive provides spectacular views and a few white-knuckle moments, as the road is steep, serpentine, and completely lacking in guard rails. Start at West Horseshoe Park, which has the park's largest concentrations of sheep and elk, and head up the gravel road, passing Chasm Falls (there are
a few places to park for a quick hike). The road is generally open from July through mid-October.
Runs north of and roughly parallel to Trail Ridge Road, starting near Endovalley Campground (on east) and ending at Fall River Pass/Alpine Visitor Center (on west), Rocky Mountain National Park, Colorado, United States
