Nine miles of multi-use trails, including 6.7 miles of the Bay Area Ridge Trail, wind through oak woodland, rolling grassland and chaparral, and hawks and golden eagles are often overhead. Visitors must travel counterclockwise on the Aquila Trail. There are picnic tables and trash cans but no restrooms or drinking water. Dogs and drones are not allowed, and there is no access from Alum Rock Park via Alum Rock Falls Road. The 37-space lot closes when full and parking along Sierra Road is prohibited, so arrive at least an hour before sunset. A mountain lion was sighted here on August 27, 2026. ## Similar picks in San Jose - [Coyote Valley Open Space Preserve](https://grassyknees.com/san-jose/activities/coyote-valley-open-space-preserve--listing-4cd8e90afc18620b6513dae4) — Sunday–Saturday 7:00 a.m.–6:30 p.m. Closed Monday, October 26 and Tuesday, October 27… · Coyote Valley Open Space Preserve, Morgan Hill · All ages · Free · checked Oct 24.
