Most of the town is in the Portola Valley School District for kindergarten through 8th grade. Ladera and some nearby areas are in the Las Lomitas Elementary School District. High school students attend the Sequoia Union High School District, which serves the area through Woodside High School.

School boundaries change. Confirm the assigned schools for any address with the district before you buy.

Alpine Road and Portola Road are popular cycling routes, and the town has a network of walking and riding paths.

What to check before you buy

  • The San Andreas Fault runs through Portola Valley. The town publishes geologic hazard maps. Check fault and landslide zones by parcel.
  • Much of the town is in mapped wildfire hazard zones. Get insurance quotes early, and check defensible space requirements.
  • Many homes use septic systems. Inspect the system and confirm permits.
  • Ladera and some addresses with a Portola Valley mailing address sit outside the town limits. Confirm which agency handles permits and services.
