Boreas Pass

Boreas Pass (pronounced "bor-ee-yus") follows the Denver, South Park and Pacific Railroad bed. As it was originally designed for a railroad, the route is gentle, smooth, and never climbs at more than a gradual 3% grade. (My wife has nicknamed it "Boringest Pass.") The road is easily passable by passenger cars in almost any weather. However, much of the road is above treeline and the summit crosses the Continental Divide at 11,500 feet, so be prepared for high alpine conditions, including rapidly changing weather. Numerous hiking trail trailheads dot the route. The road is popular with cyclists and distracted tourists. Stay alert and be cautions and courteous.
