Major city · United States
Sunnyvale
Base in Sunnyvale only if you need a South Bay bed near Caltrain: 1 night for downtown Murphy Street, or skip it and stay in San Jose or Mountain View.
Sunnyvale is a Silicon Valley suburb with a small, walkable old downtown on Murphy Street and two Caltrain stops. It is not a sightseeing city: the draw is a quiet, safe base between San Francisco and San Jose, with cheap and varied food along El Camino Real. Most travellers pass through on Caltrain or use it for one or two nights while working or visiting the valley.

- 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.

Getting around
Caltrain runs through downtown Sunnyvale and Lawrence, linking San Francisco and San Jose. VTA bus 22 is the main El Camino Real line; bus 522 is the faster limited-stop version. VTA light rail also serves Sunnyvale but does not connect directly with Caltrain. Bikes are allowed on Caltrain, VTA buses and light rail at all hours, and many roads have bike lanes. A car helps for strip-mall food and offices.
