About This Route
Palo Alto sits about 21 miles south of SFO in the heart of Silicon Valley, home to Stanford University, Sand Hill Road venture capital firms, and the headquarters of numerous tech companies. The ride follows US-101 south through San Mateo and Redwood City or takes the scenic I-280 along the Crystal Springs Reservoir through the foothills of the Santa Cruz Mountains. University Avenue, Palo Alto's main commercial strip, is lined with restaurants, shops, and the Stanford campus entrance.
Surge Pricing Alert
Southbound 101 fills with tech commuters between 3:30 and 7 PM on weekdays, and rideshare prices from SFO climb right along with it. Stanford football Saturdays bring localized demand near the stadium each fall. Twice a year, Y Combinator Demo Day and the major tech conferences send short, sharp surges through the Palo Alto area.
Travel Tips
- 1The I-280 route through the peninsula foothills is slightly longer in distance but often 10–15 minutes faster than US-101, especially during afternoon rush — request it if your driver defaults to 101.
- 2Caltrain runs from Millbrae station to Palo Alto station for about $6.25 and takes 35–40 minutes — a strong option for solo travelers. Take BART from SFO to Millbrae to connect (about $6 with the airport surcharge).
- 3If you're visiting Stanford campus, ask your driver to drop you at the Palm Drive entrance off University Avenue for the most convenient access to the main quad.
- 4Palo Alto's downtown parking is notoriously difficult — another reason rideshare beats rental cars for short Silicon Valley visits.

Should I take 101 or 280 from SFO to Palo Alto?
I-280 is usually faster, especially during afternoon rush hour. It runs through less-developed foothills with fewer merge points. US-101 has more exits and commercial traffic that creates bottlenecks through San Mateo, Belmont, and Redwood City. Ask your rideshare driver to take 280 if you want the smoother ride.
