Local checks

Start with the details that can change the answer

City limits, county offices, water providers, and special districts can all matter. These are the first things to check for a Silverton address.

  • Confirm whether a parcel sits inside Silverton town limits or in unincorporated San Juan County — it changes which zoning, building, and permitting rules apply, since Silverton is the county's only incorporated town.
  • Check the San Juan County Assessor for the parcel's valuation, mill levy, and whether any old mining claim, easement, or split mineral estate is attached to the title.
  • If you plan to rent short-term, verify the Town of Silverton vacation-rental license and lodging-fee requirements plus the San Juan County lodging tax before you list.
  • Ask about water and wastewater service versus a well or septic, and confirm year-round road access and winter maintenance — US 550 over Red Mountain Pass can close for storms and avalanche control.

Get to know Silverton

Why this place feels like itself

Silverton is the county seat and only incorporated town in San Juan County — the highest county in the United States, averaging over 11,000 feet — and the whole town is a National Historic Landmark reached in summer by a coal-fired narrow-gauge train from Durango.

Silverton sits in Baker's Park, a high valley in the heart of the San Juan Mountains where Cement Creek and Mineral Creek meet the Animas River, at an elevation of 9,318 feet. Prospector Charles Baker found a little gold here in 1860 and talked up 'Baker's Park' so effectively that hundreds rushed in — only to find far less easy gold than advertised, a brutal climate, and land that was still Ute country. They drained out complaining of the 'San Juan Humbug,' and the Civil War kept others away for years. The area was formally Ute land under an 1868 treaty until the 1873 Brunot Agreement opened the San Juans to mining and settlement. Silverton itself took shape in 1874 — Francis Marion Snowden built the first log cabin that year — and the town won an election that fall to take the county seat away from nearby Howardsville.

What made Silverton was ore and, finally, a railroad. Its central spot at the confluence of several streams made it the natural supply, smelting, and social hub for a ring of high mining camps — Animas Forks, Eureka, Howardsville — but the remote San Juans couldn't really pay until heavy ore could move cheaply. That changed when the Denver & Rio Grande Railway reached town in 1882 and set off a long boom; the population quickly doubled to around 2,000. San Juan County itself, named for the surrounding mountains, had been established in 1876 just before Colorado's statehood. The town filled with the brick-and-false-front commercial buildings and the Grand Imperial Hotel (built 1883) that still line its streets today — a mining-era streetscape complete enough that the whole town was designated a National Historic Landmark in 1961.

The mines wound down through the twentieth century, and Silverton's last major mine and mill closed in the early 1990s. What carried the town through was the train. After World War II, passenger traffic climbed on the narrow-gauge line down to Durango, and by the 1960s the railroad — now the Durango & Silverton Narrow Gauge Railroad — was actively courting tourists, delivering a steady stream of visitors that helped Silverton survive when the ore ran out. Today about 600 people live here year-round, in the only incorporated town of San Juan County, which at an average elevation of roughly 11,240 feet is the highest county in the United States. Most of the surrounding land is national forest, and US 550 — the 'Million Dollar Highway' — threads north over Red Mountain Pass toward Ouray, one of the most spectacular and demanding mountain drives in Colorado.

Silverton is a National Historic Landmark town where Greene Street's brick storefronts, the Grand Imperial Hotel, the mining museum, and the old jail preserve the county-seat core. In summer, the narrow-gauge train arrives from Durango and old mining roads lead into the surrounding San Juans. Ice Lake Basin and the Million Dollar Highway begin nearby. Winter quiets downtown and shifts attention to deep snow, winter travel, and the mostly guided slopes at Silverton Mountain.

Worth knowing

Silverton sits at 9,318 feet. Winters are long, and U.S. 550 over Red Mountain Pass can close for storms or avalanche work. Groceries, specialty medical care, and other services may require a drive to Durango or Montrose, so allow for altitude, winter tires, road reports, and weather delays.
