Guanella Pass reopens early, unlocking Colorado mountain views and trails

Guanella Pass is opening early enough to feel like a spring bonus: the 24-mile Scenic Byway will reopen at 9 a.m. Thursday, April 16, six weeks ahead of its usual Memorial Day weekend start. Clear Creek County credited unseasonably low snow levels, plus a coordinated push from Clear Creek County Road and Bridge, Park County Road and Bridge and the United States Forest Service, for getting the mountain route ready ahead of schedule.

That matters because Guanella Pass is more than a pretty drive. The road climbs above treeline and gives Front Range travelers one of the fastest ways into classic high-country scenery, with views that include Mount Bierstadt, Mount Blue Sky and Argentine Pass. The byway can be reached from either Grant or Georgetown, making it an easy shoulder-season day trip when the mountains are still holding onto some winter.

The access is especially useful for hikers. The Forest Service says the south side opens the door to Geneva Creek, Whiteside, Threemile, Burning Bear, Abyss Lake, South Park, Rosalie and Mount Bierstadt Trail #711, while the north side serves Silver Dale Townsite Historic District and Silver Dollar Lake Trail. At the summit, a short interpretive trail adds a quick stop with a viewpoint, which makes the pass appealing even for drivers who are not planning a full hike.

The early opening does not mean summer-like conditions. Clear Creek County said Guanella Pass Road is seasonally closed after Thanksgiving and normally reopens around Memorial Day weekend, and officials warned that temporary closures can still happen if spring storms make the road hazardous. The county also said every vehicle must be parked fully off the paved portion of the roadway, a rule tied to safety concerns that have already led to new No Parking signs along the corridor.

Those signs were installed in 2025 after overcrowding and parking problems created traffic jams and raised concerns about access for law enforcement, medical crews and wildfire evacuation. That history makes this year’s early opening especially useful and especially fragile: Guanella Pass is back on the map for scenic drives, trailhead access and quick mountain escapes, but the spring window still comes with the same high-country rules that always govern this road.
