Rabbit Ears Pass

Rabbit Ears Pass is one of Colorado's most scenic and serene mountain drives, cruising along U.S. Hwy. 40. This route crosses the Continental Divide and winds through Medicine Bow-Routt National Forest to breathtaking views of vast valleys, alpine meadows and rugged rock formations. It’s named for the twin rock spires that resemble rabbit ears, which stand sentinel at the top of the corridor. Known for its year-round accessibility, Rabbit Ears Pass is the most popular route to take when heading into Grand County from the west.

Elevation: 9,426 ft (2,873 m)
Length: ~19 mi (30 km)

Know Before You Go: In snowy weather, Rabbit Ears Pass can be difficult to traverse for some drivers. This is due to steep grades on both sides of the pass and quite a few switchbacks. Check conditions before embarking from mid-September to May and ensure your vehicle is equipped with four-wheel drive, snow tires and/or chains. 

Visit Rabbit Ears Pass

Started in 1911 and completed in 1915 during Colorado's mining boom, Rabbit Ears Pass served as a vital route for wagons transporting goods and people through the Rockies. Today, it remains a key passage for those venturing eastward into Grand County or westward toward the national forest and Steamboat Springs. But the route is not just practical, it’s also stunning, leading travelers through aspen-filled forests, past glacial lakes and toward the many recreational opportunities in the region.

After descending from the summit, you’ll find yourself facing soaring peaks in the heart of Kremmling’s natural beauty. The road serves as a gateway to adventures in Rocky Mountain National Park, world-renowned ski resorts, natural hot springs and more.

Things to Do on Rabbit Ears Pass

Rabbit Ears Pass is more than just a route — it's a destination in itself. Along the way, take a moment to explore dramatic overlooks into sweeping valleys and meandering footpaths perfect for a quiet afternoon in nature.

Hiking

Rabbit Ears Pass has access to an array of stunning hiking trails. One of the most popular routes is the 5.5-mile Rabbit Ears Peak Trail, which leads to the iconic rock formations at the summit. This moderately challenging trek takes you through alpine landscapes, where you’ll spot wildflowers in the summer and snow-dusted trees in the winter. Experienced hikers can access Segment 73 of the Continental Divide Trail from the pass, allowing for longer, more challenging backcountry adventures that include camping in the wilderness.

Snowmobiling and Cross-Country Skiing

In the colder months, the pass transforms into a powder-covered playground for winter-sports enthusiasts. Snowmobilers flock to the area for its well-groomed paths and wide-open spaces. If you prefer to glide along more quietly, cross-country skiers and snowshoers will find peaceful trails cutting through thick, pine-scented forests and across frozen meadows.

Wildlife Watching

Keep your eyes peeled as you drive or stroll through Rabbit Ears Pass. Deer, elk and moose often wander the quaking-aspen stands, and you might even catch a glimpse of a bald eagle or red-tailed hawk soaring overhead. The area’s high-altitude lakes attract migratory birds during the warmer months, making it a great stop for birders to pull out their binoculars and explore. Remember, always maintain your distance from wildlife and follow the rule of thumb: If you can cover the animal with your thumb with your arm extended, you’re at a safe distance.

Safety and Preparation

Rabbit Ears Pass is well maintained and accessible throughout the year, but conditions can change quickly, especially in winter. Always check the weather and roads before setting out and be prepared with appropriate gear if you plan to explore the backcountry. Though the corridor has fewer steep switchbacks than other mountain roads, it’s still a high-altitude drive that demands caution.
