Forest Road 231 – Crazy Creek Road
Granite peaks and alpine solitude in the Crazies
Forest Road 231 punches deep into the rugged Crazy Mountains, where you’ll ford Crazy Creek multiple times before reaching high alpine meadows at the base of towering granite peaks. This rough forest service road starts innocently near Big Timber but quickly deteriorates into a boulder-strewn track that demands careful tire placement and skid plate protection. The payoff comes at mile 12, where the road opens into pristine Crazy Lakes basin surrounded by 11,000-foot peaks that define Montana’s wildest range.
Difficult rating due to loose rock, deep water crossings, and steep grades up to 15 percent. High-clearance 4WD absolutely required, plus recovery gear for the inevitable stuck moment. July through September only — snow lingers well into summer at elevation. No services for 60 miles once you leave Big Timber, so pack extra fuel, food, and water. You’ll find world-class dispersed camping and fishing, plus solitude that’s increasingly rare in Montana’s backcountry.
