About this place
Silicon Valley is synonymous with innovation, stretching across the South Bay and southern Peninsula of the San Francisco Bay Area. Once known for its prune orchards as the "Valley of Heart's Delight," the region transformed dramatically with the rise of the high-tech industry in the 1960s. Today, it is the global epicenter of technology, home to legendary startups and the headquarters of industry giants, housing more than 150 companies in fields like biotech, AI, and software within the Stanford Research Park alone.
While the term originally referred to the Santa Clara Valley’s cluster of semiconductor firms, it now broadly covers Santa Clara County and parts of San Mateo, Alameda, and Santa Cruz counties. Cities like San Jose, Palo Alto, Mountain View, and Cupertino anchor a region that blends suburban sprawl with pockets of remarkable charm and historical significance.
Though much of the energy revolves around business and innovation, visitors can explore the birthplace of this tech revolution—the HP Garage in Palo Alto—or enjoy a welcome respite among the redwoods of the nearby Santa Cruz mountains.

Best Time to Visit
- May through October — the prime travel window with warm temperatures, extremely low rainfall, and blue skies, ideal for wandering Stanford's campus or the outdoor corridors of the research parks.
- Avoid winter for wet weather — the cooler, rainier season brings the bulk of the annual precipitation, which can complicate a car-centric itinerary though the landscape becomes lush and green.

Planning Tips
- Public transit works in the core — you can easily navigate San Jose and Santa Clara by light rail and bus, with a free shuttle connecting the airport.
- Rent a car for flexibility — though traffic is notorious, a car is the best way to explore company headquarters scattered across the wider Peninsula and East Bay.
- Don't mix up train tickets — when traveling from SFO, remember that BART and Caltrain are separate systems requiring different tickets.
