The pass is located in southwestern Clear Creek County, in the Front Range west of Denver and south of Georgetown. The pass was named in 1953 for Byron Guanella, a road supervisor and commissioner in Clear Creek County for nearly 50 years.
The pass provides a route between Georgetown in the valley of Clear Creek to the north and Grant in the valley of Geneva Creek, a tributary of the North Fork South Platte River, to the south. The pass is traversed by the Guanella Pass Scenic Byway. The road provides a link between Interstate 70 to the north and U.S. Highway 285 to the south. From Georgetown, take Clear County Route 381 south for 11 miles to the pass; from Grant, take Park County Route 62 13.5 miles to the pass. [1]
The entire route from Georgetown to U.S. Highway 285 is paved,[2] but is not maintained in the winter and often closed seasonally after the first heavy snow. There is a parking area at the closure gate on the Georgetown side of the pass to allow access to the pass by foot or snowmobile during the winter.
At the summit of the pass, hiking trails lead east to Mount Bierstadt (elevation 14,060 ft (4,290 m)) and west to Square Top Mountain, with many other trails connecting to lower parts of the pass.
The Geneva Basin Ski Area which existed from 1963 to 1984 was located just a few miles south of the pass summit.[3]
