Continental Divide National Scenic Trail – Marias Pass Section
Continental Divide spine through Glacier's backcountry
The Continental Divide Trail’s Marias Pass section cuts through some of Montana’s most remote backcountry, following the exact spine where waters split between the Pacific and Atlantic. This 28-mile stretch runs from East Glacier Park to Essex, threading between towering peaks of the Bob Marshall Wilderness and Glacier National Park’s southern boundary. You’ll cross Marias Pass itself at 5,213 feet — the same route Lewis and Clark’s expedition sought but never found, later becoming a crucial railroad corridor.
This is serious backcountry driving requiring high-clearance 4WD and self-recovery gear. Expect deep ruts, washouts, and stream crossings that can turn dangerous during spring runoff or heavy rains. Best tackled July through September when snow clears the high country. No services exist for the entire route — pack extra fuel, water, and emergency supplies. Cell service is nonexistent. What you get is pure Montana wilderness, massive alpine vistas, and the satisfaction of driving one of the most historically significant passes in the American West.

Frequently asked questions
What kind of vehicle clearance do I need for the rocky sections along the Divide?
High-clearance 4WD is mandatory with at least 10+ inches of ground clearance. Stock pickups and SUVs with 4WD can handle it, but expect some scraping on the sharper rock ledges.
Is this trail accessible before July or after September?
No, snow typically blocks the high elevation sections from October through June. Even in early July, expect possible snow patches and muddy conditions from snowmelt.
Do I need permits to drive this section of the Continental Divide Trail?
No permits required for the trail itself, but if you're accessing through Glacier National Park entrances, you'll need the park entrance fee. Dispersed camping follows standard Forest Service rules.
What's the most challenging part of this 28-mile section?
The steep rocky climbs near the actual Continental Divide crossing around mile 15, where loose scree and tight switchbacks demand careful throttle control and spotting.
How many water crossings should I expect and are they seasonal?
Expect 3-4 creek crossings that are typically shallow (under 12 inches) but can swell during spring snowmelt or heavy rains. Late summer crossings are usually just wheel-deep.
