Trail Ridge Road

US 34 Rocky Mountain National Park, Colorado

The highest continuous paved road in the country, climbing to 12,183 feet between Estes Park and Grand Lake with eleven miles above treeline. Crews start plowing in mid-April and work from both ends until they meet near the Alpine Visitor Center. The park has kept dates since the road's first summer in 1932: the earliest opening was May 7, 2002; the latest, July 16, came in that half-finished first season, and no year since has waited past June 26, 1943.

Trail Ridge Road: opening and closing questions

When does Trail Ridge Road close for the winter?
Closes when winter settles in for good, most often in the second half of October. The park puts the average at October 23. Across the 94 closings on record the gate has gone shut around October 29 — as early as October 2 in 1951, as late as December 2 in 1933. The winter closure covers the high stretch between Many Parks Curve on the east side and the Colorado River Trailhead on the west.
When did Trail Ridge Road close last?
The most recent closing on the record is November 14, 2025. Every other season we can source is in the table on this page.
Can you drive Trail Ridge Road in winter?
No. The high stretch between Many Parks Curve on the east side and the Colorado River Trailhead on the west is gated once the season ends, and it stays shut until spring plowing gets through. Rocky Mountain NP posts the gate's current state.
Is Trail Ridge Road open right now?
This page is the season record, not the road's condition this morning. National Park Service — Rocky Mountain National Park publishes today's state of the road, and that is the one to check before you drive — conditions turn over in hours at this elevation. For planning: the usual season runs from about May 28 to about October 29.
When does Trail Ridge Road open again?
Usually opens in the last week of May. A snowy spring pushes it into the first week of June. The median of the 95 openings on record is May 28; the earliest was May 7 in 2002 and the latest July 16 in 1932.
