Rollins Pass Road Status
The Rollins Pass Road Status (Corona Pass Road Status) and road conditions information is updated every week of the year and often daily. Updated: Wednesday, March 19, 2025 at 6:37am MT.
This Rollins Pass Road Status (Corona Pass Road Status) page is updated every week of the year and often daily. The page is updated as, when, or if conditions change; please note that closures due to search and rescue/recovery efforts, wildfires on or near the pass, avalanches, extreme fire conditions, washouts, downed trees, rockfalls, snow slides, mudslides, late season and early season snowstorms, weather, immobilized vehicles blocking the road, or other reasons are always possible—we’ve seen it all! Permanent closures and Stage 3 fire closure information is collected from official sources; all other fluid data on this page is aggregated from direct observations by the Preserve Rollins Pass team and/or crowd-sourced information available and provided to Preserve Rollins Pass. You can help: to share an anonymized update with us about ground conditions, submit a photograph/video, and/or to propose an edit, email [email protected].

Rollins Pass Road Status (Corona Pass Road Status) | Winter/Spring Commentary:
• WILDERNESS SNOWMOBILE BANS: Snowmobiles are prohibited in the James Peak Wilderness and the Indian Peaks Wilderness. The area overlooking King Lake is wilderness where snowmobiles are not permitted.
• DISCOVER MORE ABOUT THE AREA: If you’re seeking to learn more about the area, order our first or second book on Rollins Pass—signed copies available with speedy shipping.
• HELP IMPROVE THIS PAGE: Noticed different conditions than what’s described? Let us know by email.
A consistent blanket of 6 inches (or more) of snow is needed for snowmobiles or any other over-the-snow motorized vehicles. This US Forest Service depth requirement not only helps keep your machine from getting damaged but also helps preserve the underlying road as well. The west side of Rollins Pass (near Winter Park) is designated as a snowmobile trail only, meaning no cars or trucks—only snowmobiles or over the snow vehicles are allowed. (An over-snow vehicle is a motor vehicle that is designated for use over snow and that runs on a track or tracks and/or a ski or skis while in use over snow.) Some trails do require 12 inches of snow (or more); be sure to observe posted signs carefully and rely on the snowmobile use map.
⚠️ There are many blind curves—expect a snowmobile, person (skier, snowboarder, snowshoer, snowmobiler), or animal around each one and please keep within the speed limit—multiple snowmobile wrecks with “significant traumatic injuries” typically occur each season. Always ride on the right side of the trail—especially around corners, do not drink and drive/ride, don’t ride in wilderness, and respect speed limits. ⚠️
From typically late November to mid/late-April, expect winter/spring conditions with snow, snowdrifts, ice, and slush—suitable for snowmobiling, particularly on the wetter west side of the pass. (Overall, expect winter/spring conditions and potential for avalanches through early summer.)
Please stay safe and be backcountry smart; avalanches and avalanche deaths occur on Rollins Pass. Don’t rely on luck. Be prepared and carry an avalanche transceiver, shovel, and probe—as well as an avalanche airbag—and know how to use each in an emergency. Snowmobiling tips on what to pack can be found here.
❄️ View CAIC Avalanche Backcountry Forecasts for the region encompassing Rollins Pass; official backcountry avalanche forecasts are issued each afternoon by 4:30pm daily from November through May. Per CAIC, “Each forecast will have avalanche danger ratings for three elevation bands and two days, as well as up to three avalanche problems…. The afternoon forecast will have this information for the following two days. So the forecast issued on Friday afternoon will have danger ratings and problems for Saturday and Sunday. Don’t worry, we’ll still be in the office each day at 4:00 AM. If it snows a lot more, or a lot less, than we expect, we’ll update the backcountry products. Whether you plan your backcountry outing over pint glasses or coffee mugs, there will always be a valid forecast.”

Always monitor snow conditions and exercise extra caution on steep slopes, above timberline, and while navigating through drainages.

Rollins Pass Avalanche Forecast Information
Recognizing Avalanche Hazard from the Colorado Avalanche Information Center
Obvious Signs of Instability: 1) Recent Avalanches: Avalanches are a sure sign of a dangerous snowpack. Fresh avalanches mean more are possible on similar terrain features. 2) Collapsing and Cracking: When you feel the snowpack collapse beneath you, it is a clear sign that you can trigger an avalanche. Avoid similar terrain features. These collapses often make a whumpfing sound and produce shooting cracks.
Factors that Increase Avalanche Danger (Red Flags): 1) New Snow: Most avalanches happen during and immediately following snow storms. 2) Recent Wind-Drifted Snow: Drifting snow can create dangerous conditions on wind-loaded slopes. 3) Rapid Thawing/Rain: Rollerballs, pinwheels, or a slushy snow surface are clear signs the snow is rapidly losing strength. The danger of a wet avalanche is increasing if you see any of these signs.
Ways to Reduce Your Risk From Avalanches: 1) Discuss the avalanche forecast and avalanche conditions with your group. Determine what terrain you will avoid on your trip. 2) Avoid travelling on or underneath slopes steeper than about 30 degrees if you see recent avalanches, cracking or collapsing, or any of the red flags. 3) Avoid travelling on steep open slopes with dense trees, rocks, gullies, or water bodies below them. 4) If you choose to enter avalanche terrain, expose only one person at a time to the avalanche hazard. 5) Do not stop or regroup in avalanche paths or runout zones.

Up Next: Transitional Season (Late Spring & Early Summer)—typically early/mid-April through early/mid-June each year
Rollins Pass Road Status (Corona Pass Road Status) | Transitional Season Commentary for Late Spring & Early Summer:
Mother Nature is redecorating for summer.
From early/mid-April through early/mid-June, Rollins Pass is a landscape in transition: there is generally not enough good snow for snowmobiling while at the same time, not enough of the road has melted out for wheel-to-ground vehicles (including motor bikes) to get very far. Avalanche danger still exists and backcountry forecasts for Rollins Pass should be consulted. No matter how dry and promising the initial grades of the west or east sides look, there is always an impassable snow drift around the next bend, particularly at higher elevations and especially in areas that don’t receive much direct sunlight. Road washouts, particularly on the west side, occur infrequently. For well over the past decade, Rollins Pass (Corona Pass) has never been open nor passable by the Memorial Day holiday weekend. (Even Trail Ridge Road in Rocky Mountain National Park, with considerably more infrastructure and plowing teams, isn’t always open by Memorial Day weekend; in fact, it only opens on that date about 50% of the time.) To track the melt, click here.
Why does it take so long to melt? On average, the last day of frost in Denver (at 5,280 feet) is May 5th each year. Atop Rollins Pass, where the elevation surpasses Denver’s by more than 2.2 times, the snow’s reluctance to melt serves as a stark reminder of altitude’s effect on the pace of seasonal change.
When this transitional season is shown as ‘active,’ know that if you venture out, reaching the upper elevations on Rollins Pass will likely be challenging, if not impossible. On the west side, gates will be closed either at the entrance, midway, or at the trestle—gates are scheduled to open June 15th, and this is sometimes delayed a week or more due to late runoff or washouts that need repair. On the east side, vehicles get blocked/stuck before summer officially begins on Rollins Pass. This page will be updated often, starting in early June, as the next major season approaches and/or conditions improve for summer activities to take place. Typically, this transitional season lasts approximately two months before summer starts.
Then This Year: Summer/Autumn Season—typically mid/late June through early/mid/late October each year
🔥 FIRE BANS/RESTRICTIONS AND RED FLAG INFORMATION 🔥
Just one unattended campfire can completely destroy the spectacular setting of Rollins Pass. Please recreate with care. Read more here.
When fire bans/restrictions are in effect, no campfires are allowed—there are no ‘developed’ campsites on either side of Rollins Pass, no matter how well established a site or a rock fire ring appears. Dispersed (or undeveloped) campsites do not have metal fire rings, picnic tables, numbered posts, garbage service, nor toilets, and visitors are required to properly store and pack out all food and trash to prevent negative interactions with bears and other wildlife. Rocks do not make a permanent fire ring.
Review details of any fire bans and fire restrictions:
US Forest Service | Grand County | Gilpin County | Boulder County
Read more on: Fire Restrictions 101 and Red Flag Warnings | Campfire Safety Tips
Wilderness Campfire Bans/Restrictions: Campfires are always prohibited in the James Peak Wilderness per this US Forest Service page. Campfires are also prohibited in the Indian Peaks Wilderness on/near Rollins Pass by King Lake, Betty Lake, Bob Lake, Buttermilk Falls, Skyscraper Reservoir, Woodland Lake, and along the South Fork of the Middle Boulder Creek—these areas are in the Woodland BZ and Middle Boulder BZ where campfires are prohibited per this US Forest Service map; the only exception is on the ridge west of the Continental Divide (several hundred feet above Corona Lake), known as the Columbine Backcountry Zone (BZ).
Per this USFS Regional Order, “possessing, discharging, or using any kind of firework or pyrotechnic device” is prohibited in the Arapaho and Roosevelt National Forest. Exploding targets, tracer bullets, and fireworks are never allowed on National Forest System lands.
Railroad workers more than a century ago consistently mentioned high winds on Rollins Pass, which still experiences hurricane-force winds today. Times haven’t changed; please follow fire restrictions and, if allowed, keep any campfires small so the wind doesn’t spread fire and threaten the beauty and history of Rollins Pass. Drown your campfire with water, stir the embers with wet soil—ensuring all is soaked—then drown everything again. Everything (including the rock fire ring) should be cool to the touch—if it’s too hot to touch, it is too hot to leave. Learn more here.

Later This Year: Transitional Season (Late Autumn & Early Winter)—typically mid/late October through late November or early December each year
Rollins Pass Road Status (Corona Pass Road Status) | Transitional Season Commentary for Late Autumn & Early Winter:
Mother Nature is redecorating for winter.
After the first few snowstorms in late September, October, or early November, the snow accumulation becomes too deep for driving but remains inconsistent and insufficient for reliable snowmobiling, except for experienced riders familiar with navigating early-season conditions. No matter how dry and promising the initial grades of the west or east sides look, there is always an impassable snow drift around the next bend, particularly at higher elevations and especially in areas that don’t receive much direct sunlight. As temperatures drop, the snow accumulates into lasting obstructions that will likely persist until next summer. Rollins Pass becomes a landscape in transition. Avalanche danger is always a possibility; backcountry forecasts for Rollins Pass should be consulted.
When this transitional season is shown as ‘active,’ know that if you venture out, reaching the upper elevations on Rollins Pass will likely be challenging, if not impossible. On either side, vehicles get blocked/stuck after autumn officially ends on Rollins Pass. *On the west side, gates may be closed either at the entrance, midway, or at the trestle; and gates are always scheduled to close regardless of road conditions on November 15th.* The Colorado Avalanche Information Center (CAIC) typically begins to publish avalanche forecasts in early November. This page will be updated often as the next major season approaches and/or conditions improve for winter activities to take place. Typically, this transitional season lasts approximately 6-8 weeks before winter starts.
