Posted By: globreal 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.
Posted By: ssowalskie 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.
Posted By: KimberlyJS 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.
Posted By: shapovalovm Info: The road is in good condition, made to the TH in Accord with summer tires with no issues.
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.
Posted By: daway8 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.

Posted By: Gweilo climber Info: Arrived at 6.45 and lower lot was already full and several cars on the road. Upper Lot only had 5 vehicles/
32 degrees and sunny, although hazy from the California wildfires. Conditions dry and low wind. Perfect day
Posted By: BROWNIE1037 Info: Got to the trailhead around 6.45 AM. Lower parking lot was half full. Definitely a different site from about 2 months ago. Guessing the colder weather and school starting again, has lowered the crowds heading out to this very popular 14er.
Posted By: bn_shyam Info: Arrived just before 7AM, the lower lot was full and 30-40 cars parked on either side of the road. Upper lot had few cars but wasn’t full, no lines to the restromms. Departed at around 10AM, by then the upper lot was full as well as the road to the TH. There were cars parked on road till about .5 miles to the TH.
Posted By: geneseejen Info: Parked at the upper lot at Bierstadt today. Noticed a Clear Creek County deputy sheriff writing parking tickets for cars parked along the road this afternoon. Appeared to me might be wrong so you might want to check it out for sure that only the cars with wheels on the pavement were cited; those completely on the dirt shoulder did not appear to be ticketed.
