Overview
Almaden Quicksilver County Park is a massive 4,100-acre historic and ecological preserve situated in the rugged hills of south San Jose, guarding the deep historic ruins of the legendary New Almaden quicksilver mines. During the historic nineteenth-century gold rush, these mines were the absolute richest mercurial deposits in North America, attracting thousands of international pioneer miners. Today, the park features over 34 miles of scenic trails where hikers can discover abandoned brick mine shafts, mining equipment, and wild wildflower meadows.

Travel Tips
- Critical toxin warning: This park was historically a mercury mining site. Never drink from natural creeks or springs. Keep dogs leashed and prevent them from licking soil or puddles.
