Mountain Bike Trails

Multi-Use Open Space Trails

Mountain bikers can enjoy non-paved dirt or gravel trails throughout most of the East Bay Parks. Mountain bikers are welcome to ride on multi-use trails. Most multi-use trails are typically 8 feet wide in length and shared with hikers and equestrians. Check each individual park maps for which trails are accessible by mountain bikes.

Narrow Trails

Narrow trails are generally pedestrian or pedestrian and equestrian hiking trails or footpaths throughout the parks and are typically not accessible by bikes and in some cases equestrians. There are a few exceptions where bicycles are allowed on single track trails. Cyclists are allowed on these single track trails: designated sections of the Lafayette Ridge Trail in Briones Regional Park, Sinbad Creek Trail in Pleasanton Ridge Regional Park, Swallow Bay and Heron Bay Trails in Del Valle, Redtail Trail and a section of Brandon Trail from Ten Hills to Proctor in Anthony Chabot Regional Park, and Zeile Creek Trail at Garin Regional Park.

Mountain Bike Top Picks

With hundreds of miles of trails, choosing the appropriate off-road biking route isn't always easy. Thanks to the East Bay Regional Park District staff and Volunteer Trail Safety Bike Patrol, here are some of the best trails for different levels of ability:

Beginner - Entry Level (good for new mountain bikers, fairly level terrain)

  • Quarry Lakes in Fremont - Trails are all level graveled surfaces; 4-5 miles of trails all accessible for bikes, connects to Alameda Creek Trail which is paved on one side, gravel on the other. Bikes can ride on either side of Alameda Creek Trail
  • Point Pinole in Richmond - More than 12 miles of mostly flat or gradually sloping dirt or gravel trails. There is one asphalt trail about 1.5 miles long from the parking lot to pier. Bikes are permitted on the pier, which juts about 1/4; mile into the San Pablo Bay. Lots of loop options from the asphalt trail but beginners may want to stay on the East side of the park on Marsh Trail and Cook's Point Trail. The West side trails such as Bay View Trail are slightly more rolling along some fairly steep cliffs. More advanced riders will enjoy the challenge and views on this side.
  • Diablo Foothills in Walnut Creek from Castle Rock Staging Area - At this time, bikes are not permitted on the paved road that runs by Castle Rock Recreation Area but they may ride on the dirt path directly behind Castle Rock. This may be a bit of a challenge for beginners but go ahead and push your bike until you reach the intersection with Stage Road Trail. This 1 mile long trail is perfect to test out skills on rolling hills, through creeks, and shaded woodlands. Riders will likely encounter lots of horses so be polite when sharing the trail. The trail end at Mt. Diablo State Park. Cyclists can continue into Mt. Diablo but the trail begins to climb pretty quickly.
  • Lake Chabot Paved Path with Trail Option in Castro Valley - This 4 to 8 mile roundtrip ride is a step up from an entry level. Older kids will love it. This section is part of the longer Chabot Bike Loop but for beginners, we suggest an out and back. Start by taking the recently re-paved Eastshore Trail. It's made up of rolling hills so watch your speed. This is good practice for changing gears. The paved trail turns to dirt. Look for the bridge on the left. Carry your bike across the bridge and resume riding on the dirt path. Be Warned! Don't take the regular Chabot Bike Loop unless you want to tackle a mile long technical ride with a 1,000 foot elevation gain. You stay on the flat Honker Bay Trail which hugs the lake. This is good practice riding on a typical dirt trail. Turn around and head back when you're ready.
  • Others Parks - Round Valley, Morgan Territory, Sunol (Camp Ohlone Road)

Intermediate

  • Del Valle south of Livermore - This is an out and back ride that can be anywhere from 2 to 14 miles. Take the East Shore Trail from the marina which is a wide dirt and gravel road for about one mile. At the Swallow Bay trail, you can ride on single tracks hugging the lake. These trails require a high level of fitness but for the most part can be ridden by riders that are fairly new to the sport. There are many places one can get off of the single track in favor of the fire road if the single track proves overwhelming. The ride is long with many changes in topography and scenery. This is also one of the few places in the district that if the ride gets too hot you can cool off in the lake! No lifeguards so swim at your own risk.
  • Anthony Chabot in Oakland Hills - This 8.5 mile loop will take your through the heart of this regional park including open grasslands and shady forests. This makes a nice intermediate ride, traveling on a portion of the Chabot Bike Loop without the major hills. From Bort Meadow off of Redwood Road, ride on Grass Valley Trail, south for about 1 mile. Then turn left up Redtail Trail (east) for a little over 3 miles to day use parking area located at the intersection of Brandon Trail and Marciel Road (where you can also park) then turn right (west) on Brandon Trail all for 4.6 miles back to Bort. It is slightly uphill on the way back. Another route, that is easier, is stay on Grass Valley Trail and turn left on Brandon Trail to the day use parking area then return on Brandon Trail all the way back to Bort Meadow. You can also start your ride at the day use parking area.
  • Redwood Regional Park Bike Loop in Oakland Hills - This 8.22 mile loop circles Redwood Regional Park in the Oakland Hills along the East Ridge and West Ridge Trails. Most cyclists do this loop in a counterclockwise route. West Ridge is moderately technical with rocky sections and a steep descent. Canyon Trail to get to East Ridge from the main Redwood Gate entrance is a steep uphill but the rest of the loop is fairly moderate.
  • Others - Briones, Pleasanton Ridge, Lake Chabot Bike Loop
