Almaden Quicksilver County Park covers 4,152 acres and occupies the majority of Capitancillos Ridge. It is noted for its natural diversity and as a landmark of California history. Mining activities have been conducted in this area for more than 135 years, and it once was the home to over 1,800 miners and their families. Remains of that era offer a glimpse into what mining operations were like in the latter part of the 19th century.
In early spring, Almaden Quicksilver County Park provides a spectacular display of wildflowers. Found here are more than over 34 miles of trails for hiking, with equestrian trails that stretch out for 23 miles and bike trails running another 10 miles. All trails are open to pet owners, although dogs must be walked on a leash.
Scattered around the park are numerous picnic tables. Watering troughs for horses are also available at some locations. Potable water, however, is only available at the Hacienda and Mockingbird Hill entrances. In fact, due to the old mining operations, mercury has been measured at high levels in Guadalupe and Almaden Reservoirs, rendering the fish from those bodies of water unsafe to eat. Anyone fishing here is advised to follow a strict catch and release policy.
Almaden Quicksilver County Park is open daily from 8am till sunset. There are no fees required at any of the entrances.
