Trail Ridge Road

What should you know before visiting Trail Ridge Road?

No toll roads expected for a car. Mountain passes: Trail Ridge Road (3,713 m, usually open June–September).

• The road usually closes in mid-October and usually reopens in the last week of May, weather permitting. Temporary closures can happen at any time.
• About 11 miles run above 11,500 ft, with few guardrails and no shoulders. Winter brings drifting snow, high winds and freezing temperatures above 10,000 ft, so pack warm layers.
• In 2026, entering the park between 9 a.m. and 2 p.m. needed a timed entry reservation from late May to mid-October. This is the option for a Trail Ridge Road drive. Check the park's page, as rules change.

The drive

The paved road is 48 miles long and links Estes Park on the east side with Grand Lake on the west side. Its high point is 12,183 ft, and the park calls it the highest continuous paved road in the United States. The Alpine Visitor Center at Fall River Pass stands at 11,796 ft. Allow 1.5 to 2 hours one way in steady traffic, more with stops at Rainbow Curve and other pullouts. Elk, mule deer, bighorn sheep and marmots are often on or beside the road.

Planning

The park publishes a 24-hour recorded status line for the road, and variable message signs stand along it. When the Colorado traction law is active, vehicles need properly rated tires with enough tread or an approved traction device. The park pages checked list no length or weight limit for Trail Ridge Road itself. Old Fall River Road, a separate unpaved one-way road, bans vehicles over 25 ft and those towing trailers. Check the National Park Service pages for campgrounds and fuel.
