Trail Overview
Boreas Pass is a scenic, historic high-mountain passage that offers a beginner-friendly overland route stretching 21 miles between Breckenridge and Como. Crossing the Continental Divide at an elevation of 11,493 feet, this well-maintained gravel road is accessible to standard two-wheel-drive vehicles, making it an excellent introductory drive for families, sightseers, and those looking to experience Colorado's high country without demanding technical obstacles. Starting from Breckenridge via Broken Lance Drive, the route climbs gently from 9,673 feet through dense stands of aspen and pine, offering incredible views of the Tenmile Range. The road follows the historic 1882 narrow-gauge grade of the Denver, South Park & Pacific Railroad, ensuring a consistent, manageable incline throughout the journey.
At the summit, visitors can explore the restored Section House, which once sheltered railroad workers battling fierce winter storms, and enjoy several hiking trails branching off into the surrounding wilderness. The pass features numerous roadside campsites, making it a popular destination for overnight stays, particularly during the autumn months when the changing golden aspens draw visitors from across the state. While four-wheel-drive is not required in dry summer conditions, drivers should remain alert for oncoming traffic, mountain bikers, and SxSs that frequently share the corridor. The route descends on the southern side toward US-285 near Como, providing a seamless and highly scenic connection across the Front Range.
