Mine Hill Trail Professional Review and Guide
"The remains of the New Almaden Mines, once the richest quicksilver mines in California, give this hike an historic twist. Quicksilver (mercury) forms only in areas such as this, where serpentine rock is transformed by hypothermal conditions. The New Almaden Mines ultimately reached 2,300 feet underground; remnants of mining activity lie throughout the park. These seldom-traveled trails also provide excellent views of San Francisco Bay and Mount Hamilton. The walk is hilly, but not strenuous, along wide trails. Park activities include hiking, picnicking, and horseback riding. No bikes are allowed on the trails, and no dogs are permitted on the Randol Trail."
