Spring Opening of Trail Ridge Road
The opening and closing of the road depends on the weather. In 2017, it opened Wednesday, May 31, after late snowstorms dumped three feet of snow in the park in mid-May. In 2012, after a memorably snow-filled winter, the road had a late opening on June 6. The road’s earliest opening ever occurred on May 7, 2002. The latest it opened on June 26, 1943. The road typically opens on or around Memorial Day.
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 2021, Trail Ridge Road officially closed for the season on Oct. 25.
Sizable snow-removal equipment renders both the Alpine Visitor Center and the Trail Ridge Store closed to pedestrians and their vehicles during winter.
