Alpine Trail

The Alpine Trail begins at the Sand Hill Road and Santa Cruz Avenue intersection and follows along the eastern edge of Santa Cruz Avenue and Alpine Road. The 7.6 mile trail connects Menlo Park to areas of San Mateo County, Stanford University, and Portola Valley. The City maintains and operates approximately 2,000-foot section of the trail from Sand Hill Road to the City limits on the east side of Alpine Road.

Due to significant erosion on a portion of the trail near Junipero Serra Boulevard, the segment in the City has been deemed unsafe for travel and will remain closed until further notice. 

Project status

Closure
An approximate 1,000-foot section of the trail between Sand Hill Road and Junipero Serra Boulevard is closed to pedestrian and bicycles. This portion of the trail is on land owned by Stanford University where the City has easements to maintain and operate.

Alternate routes
Pedestrians are advised to take alternate routes and bicyclists may use the existing bike lanes along Santa Cruz Avenue between Sand Hill Road and Junipero Serra Boulevard.

Schedule
Depending on funding, pedestrian access may be restored in 2027.
