Beartooth Pass Alpine Loop

The Beartooth Pass Alpine Loop takes you into Montana’s most unforgiving high country, where the main highway is just the starting point for a network of old mining roads that climb toward 11,000 feet. This route branches off the famous Beartooth Highway near Clay Butte, following mining tracks through boulder fields and alpine tundra where weather can turn deadly in minutes. The technical sections demand precise wheel placement through loose rock gardens, while washouts from spring snowmelt create new obstacles each season.

Difficult terrain requires serious 4WD capability—rock sliders and skid plates aren’t optional here. The short summer window from mid-July to early September is your only shot, and even then afternoon thunderstorms can bring snow and lightning above treeline. Carry survival gear, extra fuel, and emergency supplies since cell service is nonexistent and rescue could take days. This isn’t a beginner route, but experienced drivers get access to some of the most spectacular alpine scenery in the lower 48, where few vehicles ever tread.
