RV travel guide
San Juan County
County seat Silverton, 387 sq mi across Colorado. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on San Juan County
Silverton sits at 9,318 ft and is the highest county seat in the lower 48 — the entire 705-person county sits above 9,000 ft, with the lowest paved point at 9,000 ft on US-550 at the southern county line.
The Million Dollar Highway between Silverton and Ouray (technically in Ouray County to the north) carries no shoulders and no guardrails on the Red Mountain Pass section at 11,018 ft, and CDOT advisories explicitly warn rigs over 35 ft to use US-160 + US-285 as the alternate east-west routing. Animas River dispersed camping on San Juan NF land north of Silverton accepts rigs up to 30 ft on the South Mineral Creek + Cunningham Gulch roads; high-clearance is recommended above 10,000 ft.
