The story of Bayhorse

Idaho's ghost towns burned fast — placer gold camps that lasted a season, then timber towns the forest is still swallowing.

Bayhorse is a ghost town in Custer County, Idaho, United States, founded in 1877, though active development of the town did not begin until 1880. Bayhorse was once a thriving mining town, principally supported by large nearby silver deposit. In 1882, the town increased its smelting capabilities, producing $300,000 ($10 million in 2025) worth of silver over the course of the year. By 1885, the town had grown to 300 residents, supported by a mill, three stores, a hotel, a restaurant, a meat market, a lodging house, and five saloons.

What you'll find today

Bayhorse 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.

Getting there

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 Bayhorse is roughly 44.3800, -114.3200 — use it as a starting point and cross-reference a current topographic map before leaving pavement.

Good to know

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.
