The Big Horn Mine in California stands as a silent witness to a bygone era of mining and exploration. Nestled in rugged terrain, this abandoned mine holds stories of ambition, hardship, and the relentless pursuit of valuable minerals. For adventurers, history buffs, and curious travelers, the Big Horn Mine offers a unique glimpse into California’s mining past. This post uncovers the mine’s history, what remains today, and how to explore the site safely and responsibly.

The History of Big Horn Mine
The Big Horn Mine was part of California’s extensive mining boom during the late 19th and early 20th centuries. Like many mines in the region, it was established to extract precious metals, primarily gold and silver. The discovery of these minerals attracted prospectors and investors eager to capitalize on the wealth hidden beneath the earth.
Mining operations at Big Horn Mine began in earnest around the 1890s. The mine quickly became known for its rich ore veins, which promised significant returns. However, mining in this area was challenging due to the remote location and harsh environmental conditions. Over time, the mine changed hands several times, with various companies attempting to sustain production.
By the mid-20th century, the mine’s output declined, and economic factors made continued operation unfeasible. Eventually, the Big Horn Mine was abandoned, leaving behind tunnels, equipment remnants, and a landscape scarred by mining activity.
Big Horn Mine Trail
Nestled within the Angeles National Forest, this trail is a lesser-known path that rewards hikers with stunning views, fascinating remnants of mining history, and a peaceful escape from city life. Whether you are an experienced hiker or a casual nature lover, the Big Horn Mine Trail provides a refreshing outdoor experience worth exploring.
Discovering the Big Horn Mine Trail
Located in the San Gabriel Mountains, the Big Horn Mine Trail is part of the Angeles National Forest, a vast area known for its diverse landscapes and outdoor activities. The trailhead is accessible from the Angeles Crest Highway, making it a convenient destination for those looking to spend a few hours or a full day in nature.
The trail itself is moderate in difficulty, stretching about 3.5 miles round trip. It winds through chaparral-covered hills and shaded groves, offering a mix of sun and shade that keeps the hike comfortable even on warmer days. The path follows the old mining route, giving hikers a glimpse into the area’s past as a mining hub.
What to Expect on the Trail
As you begin the hike, you will notice a gradual ascent leading to several vantage points overlooking the surrounding mountains and valleys. The trail’s terrain varies from dirt paths to rocky sections, so sturdy hiking shoes are recommended.
Along the way, you will encounter remnants of the Big Horn Mine itself. These include rusted equipment, old mine shafts, and stone foundations that tell the story of the miners who once worked here. Interpretive signs provide context about the mining operations and the challenges faced by those who lived in this remote area.

Wildlife is another highlight of the trail. Birdwatchers can spot species such as scrub jays, woodpeckers, and hawks. Small mammals like squirrels and rabbits are common, and if you are lucky, you might even see a deer or two. The diverse plant life includes manzanita bushes, oak trees, and wildflowers that bloom in spring.
Best Time to Visit
The Big Horn Mine Trail is enjoyable year-round, but the best times to hike are in the spring and fall. Spring brings wildflowers and cooler temperatures, while fall offers crisp air and colorful foliage. Summer can be hot, so early morning hikes are recommended to avoid the heat. Winter may bring snow or icy patches, so be prepared if you choose to visit during colder months.
