Mirror Lake Highway to Bald Mountain Pass
Expert granite crawling at 10,000+ feet
The Mirror Lake Highway cuts through Wyoming’s slice of the Uinta Mountains, climbing to 10,687 feet at Bald Mountain Pass — one of the highest paved roads in America before you turn onto the dirt. Past the pavement’s end, this route becomes a technical rock crawl through ancient quartzite formations, with mandatory tire placement over house-sized boulders and exposed ridgeline driving where a wrong move means a thousand-foot tumble. The trail connects a chain of alpine lakes including Crystal Lake and Ruth Lake, each requiring careful navigation around boggy meadows that’ll swallow a careless rig.
This is expert-level terrain that demands lockers, skid plates, and someone who knows how to read rock. Summer-only access from July through September, with afternoon thunderstorms that turn rock faces into waterfalls within minutes. No permits required, but fuel up in Kamas — it’s 50+ miles of technical driving with no services. What you get is legitimate high-country solitude and some of the most challenging granite obstacles in the Rockies, plus world-class trout fishing if you pack a rod.
