Alum Rock Park
One of California's oldest municipal parks is Alum Rock Park. It spans about 700 acres in a canyon on the city's northeast side. With around 13 miles of trails, it's a popular spot for a variety of activities, including hiking. Some of these trails are also suitable for horseback riders and cyclists.
There are various reservable and non-reservable picnic spots throughout the park. Appreciating the natural environment is a top activity since Upper Pentencia Creek runs through the bottom of the canyon with diverse landscapes on either side. One of San Jose's top hiking trails, Eagle Rock Trail at Alum Rock Park, is a must-see. There are several trailheads that climb uphill to this famed vantage point. Climb to the top for one of the best views of Santa Clara Valley in the park.
