Description

Alum Rock Park is located in the Diablo Range foothills east of San Jose. The park offers 13 miles of hiking trails and has a little something for everyone, from flat trails that allow access to Penitencia Creek to steeper hikes that climb the ridges of the South Rim Trail and the North Rim Trail. The canyon features a visitor center, ample picnic areas with picnic tables, a playground for kids, and volleyball courts. This park is a great day trip from Oakland, the San Francisco Bay Area, or the Santa Clara Valley, and downtown San Jose in the South Bay. There is a small possibility of mountain lion sightings, and you may also encounter poison oak or bobcats, but the majority of the flora and fauna are more benign. The rugged beauty of the foothills is well worth the trip.

The distance from sprawling, suburban San Jose to wide-open mountain-lion country is remarkably short--if you start out from Alum Rock Park. This track will have you walking in the wilderness in about an hour. It starts at the parking lot of Alum Rock Park on the southeast corner of San Jose, climbs steeply to the hills just beyond the city limits, then descends to the section of the park that has drinking fountains, bathrooms and other civilized amenities. From there it's a flat stroll along the burbling Penitencia Creek back to your car. Trails on this hike: Penitencia Creek Trail, North Rim Trail, Weather Loop, Boccardo Trail, Todd Quick Trail, North Rim Trail, Penitencia Creek Trail. Best times to go: Spring for the wildflowers; winter for the smog-free views after a cleansing rain. Avoid in the summer, when lack of rain and arid terrain create a high risk of wildfires.Show more
