Guanella Pass High Mountain ValleyGuanella Pass Map

For a quick study in Rocky Mountain eco-systems, you could hardly find better instruction than here. This well-settled road leap-frogs the steep divide between the South Platte and Clear Creek watersheds, passing through a succession of distinct environments. The lower elevations are green and wet, thick stands of spruce, fir, aspen, and pine rising along cascading creeks. Higher up, the streams snake through broad meadows, succoring thirsty mammals, nesting birds, and the industrious beaver, The road crests well above timberline, where every spring the grasses and flowers stubbornly renew, and the fragile tundra thaws and blossoms. This old logging and mining area flanked by Mounts Bierstadt and Evans boasts two of the state's best-preserved Victorian towns, Georgetown and Silver Plume.

Special Considerations:
Clear Creek County will close Guanella Pass Road at the Naylor Lake intersection and approximately 0.8 mile north of the Park/Clear Creek County line on December 2, 2013. The county will maintain Guanella Pass Road on a first day service to Cabin Creek Hydroelectric Plant and then on a third/fourth day basis to the Naylor Lake intersection after a snowfall. The Guanella Pass Road Information Line at 303-679-2422 ext 2 is available for updates.
