Fall Closing of Trail Ridge Road

Rising more than 12,000 feet at its tallest point, Trail Ridge Road is the highest continuous highway in the U.S. The road is closed each fall—historically sometime in October—because of the difficulty of maintaining a safe path. In 2016, Trail Ridge Road officially closed for the season on Nov. 18.

Sizable snow-removal equipment renders both the Alpine Visitor Center and the Trail Ridge Store closed to pedestrians and their vehicles during winter.
