South Pass City

Wyoming's ghost towns were mostly Union Pacific coal camps, built by the railroad and unbuilt when diesel arrived.

South Pass City is an unincorporated community in Fremont County, Wyoming, United States. It is located 2 miles (3 km) south of the intersection of highways 28 and 131. A former mining town near the Oregon Trail, it became a ghost town after later gold mines were closed. The entire community is listed on the National Register of Historic Places. The closest town is Atlantic City.

Calling it South Pass City was either optimism or a very good joke — boomtowns were never modest about their ambitions.

South Pass City is classified as a preserved ghost town: its buildings and streetscape survive close to their original form. These are the most rewarding towns to visit — and the most fragile. Stay on marked paths, don't enter unstable structures, and leave every artifact where you found it.

Its park setting is good news for visitors: maintained access and marked routes, with firm rules about leaving every structure and artifact exactly as you found it.

Head for the state park entrance, pay any day-use fee, and ask rangers about the best route to the townsite — plus any seasonal closures before you set out. The mapped point for South Pass City is roughly 42.4700, -108.8000 — use it as a starting point and cross-reference a current topographic map before leaving pavement.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.

The ground itself demands respect: open mine shafts, collapsing floors, and old wells hide in tall grass, cell service is often nonexistent, and help can be hours away. Tell someone your plans, pack more water than you think you'll need — and save the early morning or late afternoon light for your camera.
