Boreas Pass Road is a seasonal dirt route over the Continental Divide

Boreas Pass Road is a gentle gravel road from Breckenridge over the Continental Divide that is open to highway-legal vehicles only in the warmer months and becomes a winter ski route.

Published June 10, 2026 - Last verified June 11, 2026

Above Breckenridge, Boreas Pass Road climbs to the Continental Divide on a gentle, steady grade. It is a graded dirt road, fine for ordinary vehicles when it is open, and it offers a calmer way over the divide than the steep, winding passes nearby.

The thing to plan around is the season. This is not an all-year road. It opens to highway-legal vehicles in the warmer months and closes to motor traffic in winter, when deep snow takes over and cross-country skiers and snowshoers use the route instead. The exact open and close dates depend on snow and on Summit County’s decision each year.

Why this matters for a newcomer: a map may show Boreas Pass Road connecting Breckenridge toward Como in Park County, but for much of the year you cannot drive it. It is also a dirt road that can be rough or muddy in shoulder seasons, so it suits an unhurried drive, not a shortcut in a hurry.

Before driving Boreas Pass Road, check the White River National Forest and Summit County for the current seasonal road status.
