Trail Ridge Road
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.

The record
Usually opens in the last week of May. A snowy spring pushes it into the first week of June. Closes when winter settles in for good, most often in the second half of October. The park puts the average at October 23. The winter closure covers the high stretch between Many Parks Curve on the east side and the Colorado River Trailhead on the west.
