Sheridan County, Wyoming

Sheridan County sits at the base of the Bighorn Mountains in north-central Wyoming, where classic cowboy culture blends with welcoming small-town charm. Sheridan, the county seat, is often recognized as one of the West’s most appealing towns.

Rodeos are a major part of local life, but the area also has a surprising love for polo matches. The scenery is hard to beat, with rolling foothills stretching toward snow-covered mountain peaks. The Tongue River Valley is especially popular with fly-fishing enthusiasts.

History runs deep here, including the region’s connections to the Indian Wars and Wyoming’s frontier past. Ranching remains an important part of the economy, while tourism continues to bring more visitors. Locals take pride in their Western roots and are known for their warm hospitality. Sheridan County truly lives up to its spirit of being “Rooted in the West.”
