East Bay trails

Shimmering lakes, wooded glens and colorful flowers can be enjoyed along 90 miles of EBMUD trails in the East Bay. These hiking and horseback-riding paths wind through 29,000 acres of open space. EBMUD provides parking at most staging areas and stocks water on the trails for horses. EBMUD carefully manages watershed lands to protect water quality - so please, follow use rules and have your permit with you.

How to purchase trail use permits

Permits cost $3.00/day, $10.00/1 year, $20.00/3 years, $30.00/5 years. Trail permit holders can take members of their immediate family and 3 guests. Permits are not transferable.

Mountain bikes

On July 16, 2018, two trail segments of EBMUD trails in the East Bay were opened to bicycles. The multi-use segments on established service roads are open from sunrise to sunset (subject to seasonal closure) and connect to the trail system in Wildcat Canyon Regional Park and within the Pinole Valley. The Pinole Valley and Eagle's Nest Multi-Use trails offer 7.5 miles of new access in the East Bay watershed, now available for cyclists as well as hikers and equestrians.

Permits are required
Purchase a Trail Use Permit online or send us an email to request a paper application. It is unlawful for any person to enter or use any designated watershed trail without a valid Trail Use Permit in possession (EBMUD Ordinance 284, § 12.01).

Trail segment locations and characteristics

  • Pinole Valley Multi-Use Trail: This 6.7-mile trail segment consists of service roads, some sections newly open for public use, and provides a continuous stretch of trail spanning from the trailhead at the intersection of Alhambra Valley and Pereira Roads up to Pinole Ridge, then terminating at Alhambra Valley Road near the intersection with Pinole Valley Road. On this segment, expect to see rolling terrain through grasslands and oak woodlands with some challenging slopes coming off the ridge.
  • Eagle's Nest Multi-Use Trail: This 0.8-mile trail segment offers a fine downhill ride through forested lands from Nimitz Way in Wildcat Canyon Regional Park to San Pablo Dam Road.
  • Other trails: Bicycles are not permitted on any other EBMUD trails in the East Bay or the Mokelumne watershed (EBMUD Ordinance 284, § 14.01).
