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.

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.

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.

Info: Arrived at 5:10 on Saturday; lot full and 50+ cars on the road. Parked in the upper lot with three other cars and no line for the restroom.

Info: Parking lot was full at 5:00am with cars already parking on the road. Bathrooms still closed and port-o-potties pretty dirty. I think some folks are camping out of their cars overnight at the lot. I saw a couple of Coleman stoves tucked under rear bumpers. That would explain why the lot is so full so early.
Trailhead and road to lot were excellent!

Info: Guanella Pass is closed 1.8 miles before the TH for Mt. Bierstadt. It is a 1.8 mile walk along a paved, windy road, constant incline. Was not and East way to start/finish the hike.
Posted By: hogantheepic
Info: Plowed to 1.8 miles from the summer trailhead. Side note: there was a cop sitting up there today giving out warnings and presumably recording license plates for everyone up there because apparently all the county roads in Clear Creek County are closed to all non-residents, so if you go up there more than once you might get in trouble, but the first time is just a warning

Info: Road closed from the south at mile 7-8. Just wanted to drive over but not today.

Info: Got bored and ended up in Georgetown today. Hiked to summer TH with my dog in adidas tennis shoes. After the summer TH it looked like micros are all that would be needed, with real boots of course. Gorgeous day just to get out

Info: Road from Georgetown to Guanella Pass Campground (where the road is closed for the season) is plowed, including all the pull outs along the way and the parking lot at the end. There was a small layer of snow/ice left on the road but as long as your tires aren’t bald any vehicle should be able to easily make it there.

Info: Per CDOT website:

Guanella Pass Road is closed at Naylor Lake on the Clear Creek County side and Burning Bear Campground on the Park County side.
Posted By: dwoodward13
Info: Since I haven’t seen a report since WW’s...Road is in perfect shape and 99% totally dry and clear from the Georgetown side. I hiked from the Naylor Lake TH, so I didn’t make it up the whole way to the pass, but it looked the same as the rest of the road. A few small snow patches in the trees right out of Georgetown, but otherwise Clear Creek County has done a fantastic job.

Info: Got to the trailhead around 7:30am and there were already cars piled up on the road (main trailhead was full). But there was another parking lot (overflow?) that was maybe a 5 minute walk from the main trailhead starting point that was pretty much empty. Not sure why cars werent parked there but lots of parking in that lot.
