Stonewall Mine
Cuyamaca Rancho State Park · Free with park entry
The county's richest gold mine and the town of Cuyamaca City that grew around it. Foundations, a headframe replica and interpretive signs remain; the town itself is completely gone.
Ghost Towns & Mining Ruins of San Diego County
Gold camps, stage stops and desert settlements that emptied out — and how to visit what's left without trespassing.

Quick answer
San Diego County's ghost towns are mostly gold-rush and stagecoach leftovers in the mountains and the Anza-Borrego desert, an easy day trip inland from the coast. The best legally accessible sites are the Stonewall Mine at Cuyamaca Rancho State Park, where interpretive signs mark a town of 500 that vanished; the reconstructed Vallecito Stage Station on the old Butterfield route; and the mining remnants around Julian, which survived as a town rather than emptying out. Anza-Borrego holds the rest — old cabins, mine shafts and desert homesteads scattered across the state park. Go between November and April, carry more water than you think you need, and never enter a mine shaft: the shafts are the one genuine danger in an otherwise gentle day of exploring.

The mountain sites
Cool, oak-shaded and easy — the version of this trip you can do in a normal car.
Julian
Julian · 1870 gold rush
The rush town that survived by turning to apples. The Eagle and High Peak mine tour is the one place you can go underground safely with a guide.
Banner Grade ruins
Highway 78 east of Julian · Roadside
The old camp of Banner sat below Julian and washed out repeatedly. Little is left but the grade drive itself is one of the county's best.
Desert sites
Anza-Borrego is where the true empty places are. Check road conditions with the visitor center before committing.
Vallecito Stage Station
Anza-Borrego · County park
A reconstructed sod station on the 1858 Butterfield Overland Mail route, on the flat where hundreds of emigrants camped. Open seasonally.
Carrizo Badlands overlook
S-2 corridor · Paved pullout
The view over the ground the stage route crossed. It explains, in one glance, why so many settlements out here failed.
Desert homestead cabins
Anza-Borrego backcountry · Dirt roads
Several 20th-century cabins survive on remote washes. They are historic structures — look, photograph, take nothing.
Old mine shafts
Countywide · Hazard
Open shafts exist across the backcountry and are unstable and unmarked. Never enter one, and keep children and dogs on the trail.
Before you go
- • Best season is November through April. Summer desert temperatures out here are genuinely dangerous.
- • Cell coverage is unreliable past Julian. Download offline maps and tell someone your route.
- • Historic sites are protected — removing artifacts from state or federal land is a crime.
- • Never enter a mine shaft or adit. Collapse and bad air are both real risks.
Frequently asked
Are there real ghost towns in San Diego County?
Yes — mostly gold-rush and stagecoach sites like Cuyamaca City at the Stonewall Mine, the camp at Banner and desert stations along the Butterfield route. Few have standing buildings; most are foundations and interpretive markers.
What is the easiest ghost town to visit from San Diego?
The Stonewall Mine site in Cuyamaca Rancho State Park — about an hour's drive, paved access, a short walk and free interpretive signage with park entry.
Can you go inside the old mines?
Only on the guided Eagle and High Peak Mine tour in Julian. Every other shaft in the county is unmaintained and should never be entered.
When is the best time to visit the desert sites?
November through April. Anza-Borrego regularly exceeds 100°F from May onward, and dirt roads can wash out after winter storms — check conditions with the park visitor center first.
