Trail Ridge Road

Elevation : 12,183 ft (3,713 m)

Trail Ridge Road is the name for a stretch of U.S. Highway 34 and is the highest continuous highway in the United States. Also known as Trail Ridge Road/Beaver Meadow National Scenic Byway, it traverses Rocky Mountain National Park from Estes Park, Colorado in the east to Grand Lake, Colorado in the west. It crosses the Continental Divide at Milner Pass (elev. 10,758 ft/3,279 m) and reaches a maximum elevation of 12,183 ft (3,713 m), near Fall River Pass (elev. 11,796 ft/3,595 m). Near the highest point on the road is another pass, Iceberg Pass (elev. 11,827 ft/3,604 m).

Trail Ridge Road is closed during the winter, and often remains closed until late spring or early summer depending on the snowpack. It requires access to Rocky Mountain National Park even for local residents.

From Kawuneeche Visitor Center at the park's Grand Lake Entrance, Trail Ridge Road follows the North Fork of the Colorado River north through the Kawuneeche Valley. There are several trailheads along this section of the road, notably the Colorado River Trailhead, which is the western terminus of the road segment closed during the winter.
