Location
Alum Rock Park is located in the east foothills of San Jose, accessed from Penitencia Creek Road.  The Penitencia Creek Trail is partially developed and offers limited off-street pedestrian and bike access to the park. 

Description
Alum Rock Park is one of California’s oldest municipal parks.  Located within the Alum Rock Canyon in the foothills of the Diablo Mountain Range, the park’s 740 acres of natural, rugged, beauty provide visitors with many leisure outdoor activities including, hiking, jogging, bicycling and picnicking.   Due to it’s proximity to rural, natural lands, the park is home to many wild animals.  Those animals include mountain lions, bobcats, deer and a number of other smaller animals.

Special features of the park include Penitencia Creek which transects the entire park, the Mineral Springs area that contains active mineral springs and grottos, the Gazebo and the Log Cabin which was constructed in 1913. Nine reservable group picnic areas provide barbecue pits, picnic tables and nearby restrooms for groups ranging in size from 30 to 300.  Information on reservations can be obtained at (408) 794-7275.
