Trail Ridge Road Overview
Trail Ridge Road is the highest continuous paved highway in the United States, traversing Rocky Mountain National Park from the Grand Lake entrance on the west to Estes Park on the east. The road reaches 12,183 feet at its highest point above the Alpine Visitor Center, spending 11 miles above treeline on the exposed tundra.
The full one-way drive is 48 miles and takes 2 to 3 hours depending on stops. From the Grand Lake entrance, the road climbs steadily through the Kawuneeche Valley, past the Never Summer Ranch area, and then ascends rapidly above treeline to the Continental Divide.
Highlights Along the Route
The Alpine Visitor Center at 11,796 feet is the highest NPS visitor facility in the country. Short tundra walks from the center reach viewpoints above 12,000 feet in under a mile. Bighorn sheep and elk are commonly seen along Trail Ridge, particularly near the summit area.
Forest Canyon Overlook on the east side provides a dramatic view into the glacially carved canyon below — one of the most impressive vistas on the road. The Lava Cliffs near the summit are volcanic formations that create unique foreground for photography.
Planning Your Drive
Trail Ridge Road is open approximately late May through mid-October, weather dependent. Check nps.gov/romo for current road status — unexpected closures due to snow or ice occur. The road can be driven in either direction; starting from Grand Lake means the most dramatic ascent happens first.
Dress for 40°F and wind at the summit even on warm summer days — the temperature differential between Grand Lake (72°F) and Trail Ridge (45°F and windy) is significant.
