San Juan Mountains: High Pass Progression
Choose from eight routes near Silverton, Ouray, and Telluride. Start on a short alpine road. Add high passes, shelf roads, and an expert descent later.
WHY IT FITS
Why this progression can fit your trip.
The routes share one mountain region. Each stage adds altitude, exposure, rough ground, or a longer day without resetting the progression.
ROUTE PROGRESSION
Add one skill at a time.
Drive only the stages that fit your vehicle, experience, weather, and current access. A later stage is not a required finish.
U.S. Basin
- Route distance
- 9.3 mi
- Allow
- 2–3 hours
Start with a short alpine road. Use it to check altitude, weather, and braking before a full pass.
Access note: Source snapshot: Open. Check the live source before travel.

ROUTE READINESS
Do seven checks before you leave pavement.
surface
Loose alpine road, shelf sections, rock, and steep descents
clearance
Extra clearance and strong tires; later stages need technical clearance
remoteness
Mountain towns are near, but recovery can be slow and costly
charging
Verify the valley charger before each climb and keep descent alternatives
cell Coverage
Download routes and closure notices before the pass
weather
Avoid thunderstorms, active runoff, snow, and freeze-thaw damage
turnaround
Turn around before the next section removes a safe reverse or exit
BEFORE YOU GO
Make these decisions while you have a signal.
- Check the current pass report for every route
- Acclimate before the highest stages
- Set a firm weather and battery limit
TURN AROUND WHEN
Follow the limits that you set.
- Water or loose rock is moving across the road
- Wheelspin is needed to continue
- Cloud or fatigue removes the safe margin
CARRY
Prepare for common problems.
- Tire repair and recovery equipment
- Warm layers, food, and water
- Offline maps and satellite communication
