Trail Information

Highlights

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.

Great pass trail. Took the Wilderness OB. No issues. Some hard pack snow in shade and on North face. Went from Come to Breckenridge.

4 stars for the views of the fall aspen colors, snow capped mountains and lake. Otherwise just a passenger vehicle road. Ran it from Breckenridge to Como on a Saturday morning so it was busier then normal. Lots of rental cars that were probably tourists from out of state. You have to run this road during the peak fall colors at least once. It's like driving through a tunnel of gold in some spots. This year we missed the peak by a week.

I've run this twice now. First time was in the Summer and it's decently pretty, but kind of boring. Ran this in Fall (Breck -> Como) and definitely recommend if you want to go see the trees change. Breck side is crazy busy when the trees are changing, but it thinned out when I got on the Como side of the pass. I'd probably rate it 3 Stars during the Summer but 5 when the leaves are changing! Nice bonus is it spits you out on the other side of Fairplay so you won't get stuck in traffic. It's a simple maintained dirt road that's wide enough for 2 vehicles almost the entire way through. You could honestly probably get a passenger car all the way over (but it'd be bumpy).
