Trail Ridge Road in Colorado is the highest continuous paved highway in the United States, offering sweeping tundra vistas, abundant wildlife, and an unforgettable alpine crossing through Rocky Mountain National Park.
Trail Ridge Road traces a route that Indigenous peoples traveled long before European settlers arrived, crossing the Continental Divide through what is now Rocky Mountain National Park. The modern highway was completed in 1932 and quickly became one of the most celebrated scenic drives in North America, threading above treeline for roughly eleven miles at its highest elevations.
The drive itself is the main event. Broad tundra meadows give way to sheer drop-offs and panoramic views stretching toward distant peaks. Elk graze near the road in early morning, and golden eagles ride thermals overhead. Heading west from Estes Park, you pass through Horseshoe Park, a wide valley known for elk herds and the remnants of an ancient glacial moraine.
On the western descent, the road winds down toward Grand Lake, Colorado's deepest natural lake, where waterfront restaurants and a charming boardwalk make a satisfying end to the crossing. Guided hikes depart from several trailheads along the corridor for those who want to step off the pavement and explore the tundra on foot.
Few drives in the American West match Trail Ridge Road for sheer elevation and unobstructed scenery, making it a journey worth planning an entire trip around.
Visit between late June and mid-October, the only window when Trail Ridge Road is reliably open all the way through.
Arrive at the higher elevations before noon to avoid the afternoon thunderstorms that build quickly over the tundra.
Bring layers even in midsummer, as temperatures at the summit ridge can drop sharply and wind chill is significant.
Stop at the Alpine Visitor Center near Fall River Pass for exhibits on tundra ecology and a warm cup of coffee.
Watch for marmots and pikas near rocky outcrops along the road, especially in the early morning hours when they are most active.
