Pearl Pass
Where mountain biking was born, now a 4x4 classic.
In 1976 a handful of riders hauled clunker bikes over this pass from Crested Butte to Aspen, and the Pearl Pass Klunker Tour became the root of mountain biking. Today you do it in a rig. You leave Crested Butte up Cement Creek, climb through spruce and aspen, and the road turns into a rough rocky grind above treeline. Near the top the road narrows to a shelf with serious drop-offs, and you crest at 12,705 feet in the Elk Mountains. The west side drops toward Ashcroft ghost town and the paved road into Aspen. Mind the weather. Afternoon lightning on the pass is a real risk.
Rated Difficult for one reason: it’s rough, narrow, and long. You need a high-clearance 4WD, good tires, and ideally a short wheelbase, since a few switchbacks are tight. Lockers help but aren’t mandatory if you pick lines carefully. Expect washed-out ledges, loose rock, and a few creek crossings low down. The pass is usually open early July through September, and snow can hold on well into summer. Check conditions with the Forest Service before you go. Dispersed camping is common on the Gunnison side. Bring a full-size spare, recovery gear, and layers, because it gets cold up top. You’ll be rewarded with some of the best alpine scenery in Colorado and a pass with real history. Have a dirty day.

Frequently asked questions
Can a stock 4Runner or Tacoma run Pearl Pass?
Yes, a stock high-clearance 4WD with decent all-terrain tires can do it if the driver picks lines carefully. Short wheelbase helps on the tight, rocky switchbacks, and long crew-cab rigs will scrape and may need multi-point turns. Skid plates and a spotter for the rough spots are worth having.
When does Pearl Pass open, and can I drive it in winter?
Plan on July through September. Snow drifts linger near the 12,705-foot summit into early summer and return in the fall, and it's not a winter route for vehicles. Afternoon thunderstorms are common at that elevation, so start early and be off the summit by midday.
Do I need a permit or pay a fee to drive Pearl Pass?
No permit or fee is required to drive the route itself. It crosses Gunnison and White River National Forest land, so check each ranger district for current fire restrictions and closures. Stay on the designated route, since the pass sits next to wilderness where motor vehicles are prohibited.
What's the hardest part of Pearl Pass?
The rocky, ledgy sections and shelf road near the summit are the toughest. Expect loose, uneven rock, tight turns, and exposure where a mistake means a long way down. Take it slow, use a spotter, and be ready to back up to let oncoming vehicles pass.
Is there cell service, and can I camp along the trail?
There is no cell service on the route, so download your maps beforehand and tell someone your plan. Dispersed camping is allowed in the national forest, with the usual rules: use existing sites, pack out trash, and follow any fire restrictions. Fill up on fuel in Crested Butte or Aspen before you go, and expect creek crossings that run higher during early-season snowmelt.
