Create an itinerary including Alum Rock Park
Alum Rock Park, founded in 1872, was the first municipal park in the U.S. state of California. Located in a valley in the Diablo Range foothills on the east side of San Jose, the 720 acre (2.9 km2) park offers 13 miles (21 km) of trails, varying from fairly level along Penitencia Creek to sharp switchbacks climbing to the ridges to the South Rim Trail and the North Rim Trail. The narrow floor of the valley includes a visitor center, a small museum/animal rehab facility, picnic areas, playgrounds, lawns, sand volleyball pits, mineral springs, lush plant life, woodlands, creek play opportunities, and occasional group camping.
The ridge trails offer views of Santa Clara Valley and of the valley in which the park is located. Some trails in the park are a part of the Bay Area Ridge Trail; the Todd Quick trail connects with the Santa Clara Valley Open Space Authority's 1,600-acre Sierra Vista Open Space Preserve.
Equestrians and mountain bikers have access to some of the park's trails, while others are reserved for hikers only. Cross-country teams from high schools around North San Jose, such as James Lick High School and Independence High, use the park for training and for meets.

  • This is a treasure of San Jose. May be the best of all in Bay Area. It has so many old beautiful bridges and walking along the creek is feeling like being in a fairy tail. From the gate I walked all.....  more

  • Visited park and Sierra Vista Open Space Preserve to bike. For bikers, trails and miles are limited, but the wrap-around and reward sections were fun. You will earn the fun, however, because some climbing sections, for me, were hike-a-bike. For hikers, you could spend a day hiking the perimeter. For everyone, max out the water you carry. Visited on a Monday morning and lots of people, mainly walkers, on trails. If you make it to the top you'll be rewarded with expansive views of San Jose. This park has lots of historical structures - stone bridges, train trestles, a cabin, hot spring ruins- along the paved road.
  • A must visit. Alum Rock 🤩 one of our favorite area to explore. It has all levels of hikes easy to strenuous. The best is to start from Minerals Spring, which is the last point till you could drive and park your car (there are around 6 parking spots right after you enter alum rock park gate. You should always drive at 15mph as the roads inside are curvy and there are many cyclist and hikers walking by. Parking was made free on a Sunday we visited but however is $6 Even the youth science institute is worth for children. Can end the hike with a picnic if you are with family.
