Temporary Trail Closures at Black Mountain Open Space Park

The City of San Diego has closed portions of trails at Black Mountain Open Space Park temporarily to test the soil for arsenic levels.

 Trail users still have access to most of the trails in the park including the western portion. The closed portions of the trail will be signed. Please obey the signage and use alternate routes. The rangers appreciate your cooperation.

SDMBA will keep updating as we receive more information.
