Discover more about Boreas Pass
Boreas Pass is more than just a road; it's a journey through Colorado's rich history and stunning natural beauty. Originally a route for prospectors during the Colorado Gold Rush in the 1860s, it was widened to accommodate stagecoaches before becoming the nation's highest narrow-gauge railroad in 1882. The Denver, South Park and Pacific Railroad ran until 1937, after which the route was converted into an automobile-friendly road.
Today, visitors can explore remnants of the past, including the Section House, Ken's Cabin, and a Colorado and Southern Boxcar, reminders of the original Boreas Station. The pass offers panoramic views of the Blue River Valley and the Tenmile Range, especially vibrant during the fall when the aspen trees turn to gold. Hiking and biking trails abound, providing opportunities to explore the area's diverse flora and fauna.
In winter, the road transforms into a haven for cross-country skiers and snowshoers. The Section House is open for rentals, offering a unique hut-to-hut experience. Whether you're seeking historical insights, outdoor adventures, or simply breathtaking scenery, Boreas Pass provides a memorable Colorado experience.
