Continental Divide Trail – Montana Section
High-altitude wilderness spine of the Rockies
The Montana section of the Continental Divide Trail follows primitive jeep roads and mining tracks along the actual spine of the Rockies, from the Idaho border near Chief Joseph Pass to Glacier National Park. This isn’t your typical forest service road — it’s a serious backcountry route that climbs above treeline for miles at a time, crossing exposed ridges where weather can turn deadly fast. Key landmarks include the abandoned mining district around Anaconda-Pintler Wilderness and the technical descent into the Bob Marshall Wilderness complex.
This is an expert-level route demanding a built 4WD with armor, winch, and cold-weather gear even in summer. Snow can close high passes from October through June, and afternoon thunderstorms above 8,000 feet are life-threatening. The reward is accessing some of Montana’s most remote country where grizzly bears outnumber humans and cell phones are expensive paperweights. Plan on 7-10 days for the full 400-mile traverse, with fuel caches pre-positioned since services are 100+ miles apart. Only attempt with multiple vehicles and serious backcountry experience.

Frequently asked questions
Can a stock lifted Tacoma or 4Runner handle this trail, or does it need to be fully built?
A stock lift is not enough here. You need a purpose-built rig with skid plates, rock sliders, a snorkel or at minimum a high air intake, and a suspension setup dialed for sustained technical terrain over multiple days. Breakdowns happen far from help, so armor isn't optional.
When does the Montana CDT actually become passable and when does it close down?
July through September is the realistic window. High passes hold snow well into June, and early October storms can shut things down fast. Don't push the shoulder seasons on a 400-mile expert route without current local intel.
Do I need permits to drive or camp the Montana CDT section?
No permit is required for the drive itself, but you're crossing multiple US Forest Service districts. Dispersed camping is allowed under standard USFS rules — 14-day stay limits apply, and some areas near wilderness boundaries restrict motorized access, so check the specific district maps before you go.
What's the hardest section and what makes it genuinely dangerous?
The exposed high-altitude ridge sections above 8,500 feet are where things get serious — loose rock shelves, off-camber traverses, and zero bailout options for miles. The combination of remoteness and sustained technical terrain over 7-10 days means a single mechanical failure or injury is a real survival situation, not an inconvenience.
There's zero cell service for the whole route — what's the realistic gas and resupply situation?
Wisdom, MT is your last reliable fuel stop near the southern end; plan your fuel range carefully because services along the route are extremely sparse and some marked towns are just a dot on a map. Carry maximum fuel capacity, pack all food for the full duration, and bring a satellite communicator — this is not a trail where you can call for help.
