👉 When does the Alpine Loop open?
⸻
🏔 What Is the Alpine Loop? (And Why It’s a Must-Do)
The Alpine Loop Scenic Byway is one of the most iconic off-roading adventures in Colorado, connecting Silverton, Lake City, and Ouray via:
- Engineer Pass
- Cinnamon Pass
This high-alpine route takes you through:
- Wildflower-filled basins
- Historic mining towns like Animas Forks Ghost Town
- Jaw-dropping mountain views in the San Juan Mountains
It’s consistently ranked as one of the best things to do in Silverton, Colorado and one of the top family-friendly adventures in Southwest Colorado.

📅 When Does the Alpine Loop Open? (2026 Update)
For Most Visitors (Street Legal Vehicles)
There is no fixed opening date for the Alpine Loop.
The Alpine Loop typically opens and is accessible:
👉 Mid to Late May (most years)
👉 Fully accessible by early to mid-June
This depends on:
- Snowpack levels
- Spring weather
- Road clearing progress on Engineer & Cinnamon Pass
AS SUCH, this year in 2026 we are anticipating with the low snowpacks that Lake City is accessible via Engineer Pass starting in mid-April or earlier.
Typical Closing Timeline
👉 Mid-October (weather dependent)
⸻
🚨 IMPORTANT: OHV / Side-by-Side Access Dates (2026)
If you’re planning to explore using a RZR, ATV, or side-by-side rental in Silverton, this is critical:
👉 FULL Alpine Loop OHV Access Dates:
June 1 – September 30 (2026) (conditions permitting)
Why this matters:
- There is a 3-mile highway section connecting the loop
- OHVs are ONLY legal on this section during these dates
- Law enforcement actively patrols → tickets are common
Outside These Dates?
You can still ride:
✔ Engineer Pass (Silverton ↔ Lake City)
❌ But NOT complete the full Alpine Loop
And we believe in 2026 we are anticipating early access time frames. With the low snowpacks we experienced this winter, we think that Lake City will be accessible via Engineer Pass starting in mid-April or earlier.
