Boreas Pass reaches 11,480′ as it crosses the Continental Divide from Como to Breckenridge, Colorado. The road was used by prospectors during the Colorado Gold Rush, then widened for use as a stage coach road, and widened again for a railroad passage over the divide. Today it is a scenic way to travel between highway 285 and Interstate I-70. The road is suitable for 2WD vehicles during good weather and is normally open from late spring until mid-autumn each year. Once it becomes covered with snow in the winter, Boreas Pass is a popular cross country ski route.
