Wind River Canyon Back Road
Old wagon route through Wyoming's geological showcase
While most folks blast through Wind River Canyon on US-20, the old wagon road that parallels the Wind River offers a slower, rougher alternative past towering limestone cliffs and ancient geological formations that tell the story of Wyoming’s prehistoric seas. This forgotten route connects several ranch access roads and old petroleum exploration tracks, requiring navigation skills and local knowledge to link the segments through what locals call the “back door” to Thermopolis.
The route demands high-clearance vehicles and 4WD in several sections where the track climbs over exposed bedrock and drops through loose shale. Some private land requires respectful passage—stay on the main track and close all gates. Best tackled in dry conditions from May through October, as wet clay sections become impassable slip-and-slide nightmares. No official camping, but the route connects to BLM land with dispersed opportunities. Cell service is spotty at best. This is old Wyoming at its finest—empty country where you might not see another soul all day.

Frequently asked questions
Can a stock Jeep Wrangler handle Wind River Canyon Back Road?
Yes, but it's challenging - you'll need high-clearance 4WD and experience with technical terrain. The rock gardens and loose sections will test your undercarriage and traction control.
Is Wind River Canyon Back Road open in winter?
No, snow and ice make this trail impassable from November through April. Stick to May-October when conditions are manageable and you won't get stranded.
Do I need permits to run the Wind River Canyon Back Road?
No permits required, but respect private land boundaries where the trail crosses - stay on the established route. Some sections cross BLM land with standard backcountry rules.
What's the hardest part of this trail?
The technical rock gardens about 8 miles in will challenge your line choice and clearance. Take your time picking routes through the boulder fields or you'll be calling for recovery.
Are there water crossings I need to worry about?
Yes, several creek crossings that can rise quickly with snowmelt or storms. Scout them first - some are deeper than they look and the current can shift loose rocks under your tires.
