Oregon Trail Ruts Road (Guernsey)
Follow wagon ruts carved by 400,000 emigrants
At Guernsey, Wyoming, half a million wagon wheels carved ruts five feet deep into solid limestone—the deepest Oregon Trail remnants anywhere. The back road from Register Cliff winds through private ranches and BLM land, following the actual pioneer route past abandoned homesteads and Native American petroglyphs. Register Rock bears names carved by emigrants in the 1840s, while the infamous ‘Devil’s Backbone’ ridge forced wagons to single file through terrain that still challenges modern vehicles.
This route demands respect for private property and historical significance. Gates stay locked during calving season (March-May), and landowners have zero tolerance for trespassing. High-clearance vehicles handle most sections, but wet clay turns the trail impassable. Summer heat is brutal—carry water for both vehicle and passengers. The experience connects modern overlanders with the ultimate American migration story. Best visited April through October with permission from local ranchers.

Frequently asked questions
Can a stock high-clearance SUV make it through this trail?
Yes, a stock high-clearance vehicle like a 4Runner or Tahoe handles this moderate dirt road fine. The ruts and rocky sections require ground clearance but not 4WD.
Is Oregon Trail Ruts Road accessible in winter?
Best avoided December through March due to snow and mud. April through October offers the most reliable access and comfortable conditions.
Do I need permits or pay fees to drive the ruts road?
No permits or fees required. This is public BLM land with free access to the historic wagon ruts and interpretive sites.
What's the toughest part of this trail?
Rocky sections near the actual wagon ruts can be bumpy and require careful tire placement. The trail itself isn't technical, just rough in spots.
Are there water crossings on Oregon Trail Ruts Road?
Yes, but they're typically shallow seasonal drainages that dry up by summer. Spring runoff can make them muddy but rarely impassable.
