Madison Range Sphinx Creek Mining District
Brutal climb to Continental Divide mining claims
The old prospector road to Sphinx Creek climbs 3,200 vertical feet in six brutal miles, past collapsed mine shafts and rusted stamp mill foundations where miners chased quartz veins into the Madison Range backbone in the 1890s. This isn’t scenic touring—it’s steep, loose, technical driving that demands low-range and careful tire placement on crumbling granite shelves. The notorious Devil’s Elbow switchback at mile 4 has claimed more than one vehicle that tried to muscle through instead of backing up for a second approach.
Expert-level route requiring modified 4WD with skid plates, winch, and tow points. Only attempt July through September when snow clears the high sections. No permits but register at the Sphinx Creek trailhead. Fuel up in Ennis and pack multiple days of water—this is remote country with zero services. The reward is standing on the Continental Divide with the Madison Valley spread 4,000 feet below and the Spanish Peaks filling your windshield, plus some of Montana’s best dispersed camping in alpine meadows.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Sphinx Creek?
No. This trail demands a modified 4WD with a winch, skid plates, and at minimum 33-inch tires with a lift. Stock rigs will get hung up on the rock sections and have no recovery option when things go wrong — and they will.
When does the Sphinx Creek trail typically open and close?
July through September is the reliable window. Snowpack at 9,200 feet lingers well into June and can return by October, making the upper sections impassable and dangerous outside that window.
Do I need a permit to run Sphinx Creek or camp in the area?
No permit required. It's Gallatin National Forest land with dispersed camping allowed. Follow Leave No Trace, keep fires legal per current forest restrictions, and check for any seasonal closures with the Madison Ranger District before you go.
What's the hardest section and what am I actually dealing with?
The upper climb to the Continental Divide ridge is relentless — steep, loose rock with exposure and no room for mistakes. Expect sustained ledge climbing, off-camber shelf road, and sections where a winch anchor point may be hard to find, so bring a deadman or ground anchor.
How far is the nearest gas from the trailhead and is there water on the trail?
Ennis is your last reliable fuel stop, roughly 20-25 miles out — top off there. Sphinx Creek itself has water, but treat everything before drinking; you're running through old mining claims and contamination from historic operations is a real concern.
