East Bay:
(click on area names for more information)

  • Anthony Chabot Regional Park, Oakland : With almost 5000 acres of land and miles of riding trails, Chabot is one of the District's most varied parklands. The terrain winds through grasslands, chaparral, and shady eucalyptus groves or along the shores of the lake. The East Bay Skyline National Trail runs the entire length of the park. Chabot is connected to Cull Canyon Regional Recreation Area by a six-mile section of the Chabot-to-Garin Regional Trail. Luckily most of the trails here are open to mountain bikes including both fire roads and singletrack on rolling terrain.
  • Black Diamond Mines Regional Park, Antioch : This Park is situated on an abandoned mine site with 5700 acres of grassy, oak-studded hills and some rock formations. The riding is a mixture of fire roads, doubletrack, and singletrack with most of the park's trails open to bikes. The terrain is of moderate difficulty with lots of elevation change. In the wintertime, rains can soak the adobe clay surface to make some trails unridable.
  • Briones Regional Park, Lafayette and Martinez : With 5750 acres of rolling, grassy hills and secluded, shady canyons, Briones is a secret wilderness surrounded by the towns of central Contra Costa County. Luckily, almost all of the park's trails are open to mountain bikes including some singletrack, doubletrack, and fire roads. The park's highest peak is Briones at 1483ft.
  • Coyote Hills Regional Park, Freemont : Located on the east edge of the San Francisco Bay near the Dumbarton Bridge, this easily accessible park features abundant wildlife and trails that vary from flat to leg-burner. Although the hills are short, many are steep and provide a challenge to all but the best riders. Novices can stick to the flats in the eastern half of the park while hard core hill climbers can test their traction limits on the ridge that runs down the west side. Most every trail in Coyote Hills is currently open to bikes so please ride responsibly.
  • Joaquin Miller Park, Oakland: Situated in the Oakland Hills, Joaquin Miller Park contains one of the only Urban Second Growth Redwood Groves in existence. Despite being held hostage by its geographical location right at the edge of an urban area that now includes over six million people, the park retains much of its natural beauty, health, vitality, and majesty. Unfortunately a recent proposal to ban bikes from the park has rekindled the age-old dispute over equal access. Be sure to follow current seasonal bike rules carefully to avoid damaging trails.
  • Joseph D. Grant County Park, San Jose : Joseph D. Grant County Park is the largest of Santa Clara County's regional park and recreation areas. This 9,522-acre park includes some of the County's finest open space resources. The landscape is characteristic of the east foothills of the Santa Clara Valley with grasslands and majestic oak trees. Currently bicycles are allowed on half of the large park's trails. These include both singletrack and fire roads, so please observe postings carefully to keep the trails open.
  • Mount Diablo State Park, Clayton: Mount Diablo is one of the highest points anywhere in the Bay Area at a lofty 3849ft. The legal riding here is mostly fire road, but the grueling climb to the summit is very rewarding on a clear day. The views, and the descent afterwards, are just spectacular. Particularly so with the North Peak singletrack.
  • Pleasanton Ridge Regional Park, Pleasanton : This 3150-acre park is a recently-acquired land parcel that is planned as the core of a future Ridgelands park network. The oak-covered hillside is well preserved and allows bicycles access to almost all trails including some singletrack and fire roads.
  • Redwood Regional Park, Oakland : Located just a few miles from downtown Oakland is this 1800-acre urban refuge. There are beautiful groves of 150ft coast redwoods scattered throughout the park. The riding here is limited mainly to fire roads, with the East Ridge to West Ridge Loop being the most popular.
  • Shell Ridge Open Space, Walnut Creek : Shell Ridge is Walnut Creek's largest open space preserve, with 31 miles of trails for biking, hiking and riding through oak woodlands and grassland savannah on the lower flanks of Mount Diablo. Shell Ridge gets its name from the marine fossils left behind when the ocean waters that once covered the area receded. All of the legal riding here is limited to fire roads.
  • Tilden/Wildcat Canyon Regional Parks, Berkeley : These two parks are adjacent to one another in the Berkeley hills and cover a combined total of over 4500 acres. The only legal trails here are fire roads, but the size of the parks ensure you can ride for hours.
