Google's global headquarters occupies a sprawling campus of colourful low-rise buildings, outdoor volleyball courts, and the kind of free food that other tech companies have spent two decades trying to imitate. The Googleplex is not open to the general public for tours, but you can walk or bike the perimeter paths and get a sense of the scale — and the famous Android statue lawn is visible from the street.
The campus is worth visiting for the surrounding area as well. The Shoreline Amphitheatre, Shoreline Lake, and the bay trails all sit within cycling distance, and the whole area feels like the physical expression of a certain California tech optimism: solar panels, electric vehicle chargers, and workers moving between buildings on brightly coloured Google bikes. Even if you never see the inside, the Googleplex is a useful reference point for understanding why this particular stretch of the Bay Area became the centre of the modern technology industry.
If you want to go inside, attend one of the occasional public events, or try to get a guest pass through someone who works there. The visitor centre has a small Google merchandise shop that is open to the public. Access off Amphitheatre Parkway.
