2011-09-18 Grant Side I hadn‘t been up Guanella Pass in a number of years and was amazed at the improvement of the road. The Grant side is easily passable by any car, though there are some potholes and washboard. There is very little road that isn‘t paved any more and its all near Grant. The higher you get the nicer the road becomes. No snow yet on the road and leaves are starting to change so the drive is enjoyable. CO Native         
2011-09-10 I encountered some light snow on the evening of the 9/10. It lasted for a short time and didn‘t have a significant effect on the road to the trailhead. carlhancock  1       
2011-08-27 Road is paved all the way to the Bierstadt trailhead. The parking is also paved. The roadwork is ongoing but there is no longer any section of gravel between Georgetown and Bierstadt TH left. ursidae         
2011-08-15 As previously posted the sign read that the pass would be closed from Georgetown 8-11 but this was not the case today. And on the way down while there were delays (it was one lane) I did not have to wait for a pace truck they just told me that there were workers on the road, please watch for them and be careful. Worker said it would be closed 1-3. Tomorrow may be different. pepsi         
2011-08-10 Guanella Pass Road is closed 8 am to 11 am and 1 pm to 3 pm Monday thru Friday (at least this week). A pace car runs cars to the Bierstadt trailhead from 7 - 8 am. peak576         
2011-07-04 The road up to Guanella Pass from Georgetown still definitely under construction. Only dirt in some areas, but any car can make it. Only a few cars in both lots when we arrived, but overflowing by the time we returned in the afternoon. tmccormack         
2011-06-23 As is made clear here, Guanella Pass is under construction (forever it seems; I find it funny that a construction sign reads that the project will be done October 2010). Anyhow, just wanted to mention that they may close the road before 8:00am. Went up the other day, arrived at 07:45 and work was well under way. Just an FYI. Zenn         
2011-06-10 Road closures are still in effect from 8-11 AND 1-3 if you‘re coming from Georgetown. We planned our trip to get back by noon so we would miss this but we still had to wait for about 30 minutes at 12:30. WebFoot         
2011-05-27 From Clear Creek County‘s website: After two years of being closed due to a landslide, we are happy to announce that Guanella Pass Road opened for traffic at the slide site above Clear Lake at noon (Mountain Time) today - Friday May 27. Clear Creek County snow plows had been clearing the road over the summit all week. They have gotten through, a bit narrow and few icy spots, but will be making more progress as the day goes on today. With the exception of Monday, May 30, the Federal Highway Administration (FHWA) road construction project will continue with periodic road closures just above Georgetown on weekdays from 8:00am to 11:00am and 1:00pm to 3:00pm, and there will be nighttime closures Sundays through Thursday from 8pm to 6am. The FHWA road construction project is scheduled for completion in September of 2011. Jim Davies    3      
2011-05-22 Dont see how they are going to have it cleared by Memorial Day. Made it about a mile short of the winter gate closure coming up from the Grant side. Talked to a guy who came up from Georgetown - its still closed at Clear Lake Jay521         
2011-04-13 CDOT is now saying they‘re hoping to have the north side open by May 27th. Information phone line: 303-569-3251 x.2 Jim Davies         
2011-03-10 The road is fairly clear to the Geneva/Duck Lake CG turn-off, which is about 6.8 miles from 285. There is some intermittent snowpack up to that point which should be passible by 2wd vehicles. At about 7.0 miles, the road is completely snowpacked. There is a good place to turn around and park at 7.4 miles; highly recommended. There was a vehicle stuck in the road at about 7.8 miles, but was gone at the end of the day. Looked like it would be rough getting past that point. Dancesatmoonrise         
2011-03-10 Easily drove my Tacoma 7.9 miles from US 285. The last mile or so was snowpacked with some ruts starting to form which could be an issue if you don‘t have high clearance. There also are some nasty potholes on the lower section of the road. zoomie83         
2011-02-19 Made it 0.9 miles past where the plow stops comfortably in my 4runner (this is 7.7 miles from 285/Grant) SarahT         
2011-01-09 1/8 Grant side-We in a 4 runner and 2 other vehicles were able to make it about .4 miles from the winter closure. That is where all the tracks were stopping. About a mile (maybe more) below that is where the road got bad and other vehicles were parked. After snowing for over 24 hours and still going strong when we left on 1/9, there was a great deal more snow and no new vehicles made it within 1.5 miles of us. mountainmicah83         
2011-01-07 Grant side - stopped by snow at 9.5 miles (Ford Explorer 4WD). 4 miles from Trailhead. Tire tracks go further, but need high clearance. spaceman         
2010-12-26 Grant side approach - stopped by snow (Toyota Tacoma 4 WD) 0.8 mile from winter closure. Braver soul‘s tire tracks go another 0.4 mile, then snow machine track only to gate and onward to pass. Wyoming Bob         
2010-12-05 Road only becomes snowy the last four miles. Multiple 4wd vehicles made it to the winter closure at Duck Lake. I suppose an AWD or passenger car with good tires and the right person driving could also make it to the winter closure. As in the previous report, snow is drifting across the road in a few places. sdkeil         
2010-11-22 Guanella pass road from Grant is winter maintained up to Burning bear Campground. That is 5.5 miles in. The rest of the way to the Bierstadt TH is fairly passable. I drive a Subaru Wrx and had no issues till aprox 1 mile away from the TH. At this point I hit a patch of snow on the road that prevented me from going any further. A vehicle with any kind of clearance should be able to make it the whole way. thefirststraw         
2010-10-10 Clear Creek County hopes to construct a rockfall fence around November/December. weather, etc., permitting. go to their site for the most current info. cheers IdaRed         
2010-08-08 Road to TH is CLOSED at Clear Lake. We could not get through to the pass from the Georgetown (I-70) side. tnelson         
2010-06-18 NOTICE! The road to Guanella Pass from the Georgetown side has been closed near Clear Lake due to rockslide activity and will NOT reopen until at least October, 2010. Use the Grant side (from U.S. 285) to reach Guanella Pass. Will change the driving directions for the trailhead soon... BillMiddlebrook         
2010-06-05 The North bound Guanella Pass road from Grant, CO (CO 285) is open all the way to the Guanella Pass Trailhead and and is passable for any passenger car. However, the same road from Georgetown (Southbound usually accessible from I70) is closed for the whole season due to a tenuous and risky rockslide that is increasing its rate of fall (don‘t try to go that way). vintner19         
2010-05-29 The northern approach to Guanella Pass from Georgetown will be closed all summer 2010 due to the threat of rockfall near Clear Lake. But the southern approach to Guanella Pass from Grant (off US 285) is now open to the top of the pass. 14erFred         
2010-05-29 The road is open past Duck Lake now. Saw maybe a dozen cars between both parking lots. Taking 285 to get there sucks. harrise
