Beartooth Highway Off-Road Bypass
Extreme high-alpine technical challenge
When the famous Beartooth Highway closes for winter, the old mining roads above timberline stay passable for the hardcore. This brutal route climbs from Red Lodge through switchbacks carved into granite cliffs, passing abandoned chrome mines and reaching elevations where your engine gasps for air. The technical section above Rock Creek requires precise wheel placement on loose talus with thousand-foot drops just inches away. Twin Lakes marks the halfway point where most people turn around.
This is expert-only terrain requiring lockers, rock sliders, and an experienced spotter. Weather changes fast at 11,000+ feet – snow can fly any month of the year. July through early September offers the best window, but even then, expect afternoon thunderstorms. Fuel up in Red Lodge and carry extra – the thin air kills mileage. Cell service disappears once you leave town. Only attempt this if you’re comfortable with serious exposure and have the skills to self-recover on loose rock.

Frequently asked questions
Can a stock 4Runner or Jeep handle this trail, or do I actually need lockers?
You genuinely need lockers — front and rear. Loose, off-camber rock shelves at altitude punish open diffs hard. A lifted rig with at minimum a rear locker will struggle; without front lock too, you're likely getting stuck or damaging something on the hardest sections.
When does this trail actually open each year, and how short is the window?
July through September is the realistic window — snowpack at 11,000+ feet lingers well into June and can return by early October. Even in mid-July, check conditions with Custer Gallatin National Forest before heading out; early-season snow coverage on rock makes an already expert trail genuinely dangerous.
Do I need a permit to run this route, and are there any fees?
No permit is currently required for the route itself through Custer Gallatin National Forest. Dispersed camping is free but subject to standard National Forest rules — 14-day stay limits, pack-it-in/pack-it-out, and no campfires during fire restrictions, which are common in late summer.
What's the hardest section, and what makes it so bad?
The exposed rocky ridgeline segments near max elevation are where rigs get into trouble — steep, loose rock with significant drop-offs and no room for error. At 11,000+ feet, altitude affects both drivers and engines; naturally aspirated rigs lose meaningful power right when you need throttle control most.
There's zero cell service — what's the nearest point to get fuel and water before dropping in?
Red Lodge is your last guaranteed fuel and resupply stop before the trail. The 24-mile route over 1-2 days in a thirsty 4x4 at altitude will burn fuel faster than flatland driving, so top off completely. Carry all your water or plan to filter from crossings on route — there are no services once you leave the pavement.
