Portola Valley

Skip as a destination: no hotels, no public transit, one bar. Use it as a hiking stop on a Peninsula drive, or stay in Menlo Park and visit for a half-day walk.

Not yet checkedSourcesWhat these labels mean

Portola Valley is a wealthy, wooded residential town on the San Francisco Peninsula, with no hotels and minimal services. Its draw is the network of trails in Portola Redwoods State Park and the surrounding open space. Most travellers will pass through on a drive between Highway 280 and the coast, or stop for a hike and a beer at the Alpine Inn.

  • North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
  • North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
  • North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
  • United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
  • United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
  • United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
  • United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.
