Briones Trail Closure MapConstruction Notice

From April 16 - October 2018, a portion of the Oursan Trail by Briones Reservoir will be rerouted for a construction project. Trucks will remove accumulated soils from our Briones storage site, cross a portion of the Oursan Trail, exit off Bear Creek Road then travel westbound toward Camino Pablo.

For details about the construction, visit the Trench Soils Removal Project.

For trails information, call Watershed & Recreation at 510-287-0459.

Shimmering lakes, wooded glens and colorful flowers can be enjoyed along 80 miles of EBMUD trails in the East Bay. These hiking and horseback-riding paths wind through 27,000 acres of open space. EBMUD provides parking at five 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.

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.
