Almaden Quicksilver County Park is a 4,163 acres (17 km²) park that includes the grounds of former mercury ("quicksilver") mines adjacent to south San Jose, California, USA. The park's elevation varies greatly: the most used entrances (on the east side of the park) are less than 600 feet (183 m) above sea level, while the highest point in the park is over 1,700 feet (518 m) above sea level.

The park is owned by the County of Santa Clara and managed by the Santa Clara County Parks and Recreation Department. Its grounds include the Guadalupe Reservoir and features sweeping views of San Jose. Adjacent to the park is the Almaden Reservoir. The Casa Grande Almaden Quicksilver Mining Museum is located in nearby New Almaden. The park is named after the New Almaden Quicksilver Mines, which were named after the mercury mine in (old) Almadén, Spain, and produced mercury that was used to process ore during the Gold Rush.

  • This is a great place to hike because it’s good exercise but doesn’t take much time. We like to do this hike on Saturday mornings or weekday evenings after work. It’s dog friendly and my golden doodle loves it too! There’s a loop that’s about 3 miles and another one about 5 miles. You can choose which one depending on how much time you have or the amount of exercise you want to do.
  • Grew up in New Almaden roaming those hills. Remember that mercury ore was being dug here by local Indians before the Spaniards arrived, before San Jose existed, before the Gold Rush. These hills were once a bustling metropolis with thousands of people. All grown over by trees and grass. As you walk, think of the miles upon miles of tunnels and shafts, many still open though inaccessible, not far below your feet.
