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.

This is a really nice short trail. (No way it can be 4+ mile trail as described.) The creek portion of the trail in the beginning is quite unique and I saw some deers there. It only took a little more than one hour to complete. Would love to bring family someday.

Some hiking involved.

Nice beginners trail , did a mix of south rim trail and came back down the same way to do half of the creek trail. Lots of birds sighting and we were lucky to see a few deers as well. All in all a good hike !

One of my favorite hikes although I would rate doing the Boccardo part clockwise to the top as difficult.

One of the best gems in San Jose.

beautiful, lots of shade, good view for a good portion of the trail.

Short but challenging with beautiful scenic views!

Good views. Definitely moderate trail. If you are looking for peaceful and calming river water sound then this is the place.

Easy Trail. Good for summer too because of the shade. Pretty creek and you'll see different flowers on the way.

The scenery is pretty, the trail is quite easy to complete.

went back and forth a bit as I wasn't sure where the trails were. not well marked and sometimes not where the map shows. I did see a snake on the trail so beware when hiking with kids.

Great trail, definitely some good incline and rough parts to the trail. Wear long socks, your in shade for a majority of the trail with poison oak along some parts. Lots of brush and plants along side the trail. Not the most wide open but very nice.
