What you'll find today

Little stands at Bonanza today beyond foundations and scattered traces. Foundation-only sites reward visitors who enjoy reading a landscape — bring an old plat map or historic photo if you can find one, and the vanished streets start to reappear.

Public access makes Bonanza one of the easier ghost towns to actually stand in — though "public" in ghost-town country can still mean miles of dirt road, so check recent trip reports first.

Getting there

Bonanza is publicly accessible — but give the word "accessible" some respect. Out here it can still mean miles of unmaintained dirt road. Check recent trip reports, carry extra water and a spare tire, download offline maps, and let someone know your route.

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.
