The Bierstadt trail starts near the parking area on the east side of the road. The upper parking area (on the west side of the pass) has restrooms.

Info: Coming up before sunrise, it was Ice-free starting in Georgetown but gets fairly icy up until Clear Lake campground. Then completely packed down snow until the closure of the road at Naylor Lake Road junction. Back down - the sun had melted a lot out, but still took some caution. Drove up in a 02’ Accord with summer tires.

Info: As of Saturday, October 30th the paved road was completely dry except for one short section that stays in the shade. There was some snow and ice in the shadows there.

For those who don’t know, here is the info on codot.gov:
Guanella Pass Road is seasonally closed on or about Nov. 26, and reopens on Memorial Day weekend at Naylor Lake on the Clear Creek County side and Burning Bear Campground on the Park County side.

For those climbing Mt. Bierstadt or Mt. Evans from Guanella Pass during this road closure, it adds 1.5 miles each way to your hike.

Info: As of 06/05/21, the road to Guanella Pass is completely open and free of snow. There are two parking areas, the actual trailhead parking area and an upper parking lot at the summit overlook about .25 miles from the trailhead. Both parking lots have restrooms that were stocked with toilet paper. We arrived just before 6:30am and the lower parking area was completely full, with many people parking on the road, so we just parked in the upper lot and walked the extra distance to the trailhead.

Info: Road clear up to the winter trailhead at Guanella Pass campground. It had snowed over a foot, so snowshoes highly recommended (I know there was more snow coming this week, too). Snow packed, but not icy.

Info: The road is clear up to the normal winter closure 1.5 miles below the summer trailhead. The road up to the summer trailhead is hard packed and icy.

Arrived at around 7:30, saw 3 other cars in the lot. Coming back at around 1:15pm, the lot was full and cars were parking along the road.

Info: Road was almost totally dry up to the winter closure then hard packed snow to just before Guanella pass where the road and both lots were totally dry. Note there has been some avy activity at the first switchback up from the winter closure. Good time to start using that bypass option to cut past that known slide zone.

Info: No snow on the road whatsoever, but it is closed at the Duck Creek CG (*not* Duck Lake) 4 miles from the TH, coming from 285/Grant.

As a hiker attempting Bierstadt, your best bet is to take the pass south from Georgetown instead. From the closure on that end it’s only a 3 mile addition to the round trip, instead of 8.
