Trail Ridge Road crosses Rocky Mountain National Park at elevations that would be above treeline in most mountain ranges. The road spends 11 miles above 11,500 feet, topping out at 12,183 feet. Built between 1929 and 1938, it follows a route used by Ute and Arapaho tribes for thousands of years. The landscape shifts from montane forest through subalpine woods into fragile alpine tundra where growing seasons last six weeks. Marmots whistle from boulder fields. Elk graze in Moraine Park at dawn. On clear days, you can see Wyoming from the overlooks. This is what the Rockies are supposed to look like.
Parks Along the Way
Rocky Mountain National Park
Drive Trail Ridge Road. Watch elk in Moraine Park at dawn. Hike above treeline on the Ute Trail or Flattop Mountain.
Notable Stops
Beaver Meadows Visitor Center
The park's main visitor center, designed by the Frank Lloyd Wright school of architecture. Exhibits, maps, ranger advice, and the place to confirm Trail Ridge Road is open before you commit to the drive.
30 minutes
Moraine Park
A glacial valley where elk gather in herds of hundreds during the fall rut. September and October mornings bring bugling bulls and the best wildlife watching in the park. The Moraine Park Discovery Center explains the geology.
30 minutes to 2 hours
Many Parks Curve
Views of multiple mountain valleys, called 'parks' by early settlers. Horseshoe Park, Moraine Park, Estes Park, and others spread below. The name explains the landscape: these open meadows within forested mountains were grazing lands.
15-20 minutes
Rainbow Curve
The treeline transition begins here at 10,829 feet. Views of the Alluvial Fan, a debris field from a 1982 dam failure. Below, Horseshoe Park spreads across the valley floor. The trees begin to shrink and twist.
10-15 minutes
Forest Canyon Overlook
Views 2,500 feet down into a glacially carved canyon. Gorge Lakes sit at the bottom, rarely visited because the approach requires serious effort. The interpretive signs explain the geology visible from this elevation.
15-20 minutes
Rock Cut
The Tundra Communities Trail begins here, a half-mile paved loop through alpine tundra with interpretive signs explaining the ecosystem. The plants here grow a few millimeters per year. Stay on the path; footprints in the tundra last decades.
30-45 minutes
Lava Cliffs
Dark volcanic rock formations that look out of place in the granite Rockies. These are remnants of ancient lava flows, now eroded into cliffs. The pullout offers good photography and a chance to see pika in the rocks.
10-15 minutes
Gore Range Overlook
At 12,010 feet, views extend to the Gore Range 50 miles west. On clear days, you can see into Wyoming. The Continental Divide runs through here, separating Atlantic and Pacific drainages.
10-15 minutes
Alpine Visitor Center
The highest visitor center in the National Park System at 11,796 feet. Exhibits on alpine ecology, a bookstore, and the Trail Ridge Store next door with food and gifts. Short trails lead to even higher viewpoints. The elevation affects most visitors; take it slow.
45 minutes to 1.5 hours
Medicine Bow Curve
Views north toward the Medicine Bow Mountains in Wyoming. Named for the tribes who gathered here to collect wood for bows. At 11,640 feet, this is high tundra with summer wildflowers when conditions allow.
10-15 minutes
Milner Pass
The Continental Divide crossing at 10,758 feet. A small lake sits at the divide; its waters flow both to the Atlantic and Pacific. Lower and more sheltered than the alpine section, with different plant communities.
15-20 minutes
Holzwarth Historic Site
A preserved 1920s dude ranch in the Kawuneeche Valley. A half-mile trail leads to log cabins where guests once paid $11 per week for room, board, and horseback riding. Moose and elk frequent the meadows here.
45 minutes to 1 hour
The Stanley Hotel
Stephen King stayed in 1974 and wrote The Shining. The 1909 Georgian Revival hotel now offers ghost tours and a whiskey bar with 1,200 varieties. Worth visiting even if you're not staying. Views of Longs Peak from the veranda.
1-2 hours for tour
Grand Lake
The western terminus. Colorado's largest natural lake, surrounded by a small town with boardwalks and Old West storefronts. Quieter than Estes Park, with fewer services but more genuine mountain-town atmosphere.
1-2 hours
Pro Tips
- Timed entry reservations are required from late May through mid-October. Book at recreation.gov.
- The road typically opens Memorial Day weekend and closes mid-October. Check current conditions at nps.gov/romo.
- Elevation affects everyone. Drink water, take it slow at stops, and descend if you feel symptoms of altitude sickness.
- Temperatures drop roughly 3 degrees for every 1,000 feet of elevation gain. It can be 30 degrees colder at the Alpine Visitor Center than in Estes Park.
- Old Fall River Road offers an alternate one-way route (east to west only) on an unpaved historic road. More adventurous, less crowded.
- The elk rut in September and October brings animals to lower elevations. Moraine Park at dawn is the best viewing.
