The drive

Hoosier Pass carries Highway 9 over the Continental Divide between Summit County and Park County. This drive starts in Breckenridge and heads south, so the climbing and the tight turns come first, on the north side. The summit is at about 11,500 feet, one of the higher paved passes in the state.

From the top the road drops to Alma and then on to Fairplay. At 21 miles and about 30 minutes, it's a short drive, and it works as a quick way between Breckenridge and the South Platte side of the mountains.
