Foster City is a planned community of about 33,000 on the western shore of San Francisco Bay in San Mateo County, built on a tidal marsh in the 1960s. The city is known for its network of lagoons and waterways, which residents use for kayaking, windsurfing, and paddleboarding. Leo J. Ryan Memorial Park on the bayfront has good views across the bay to the East Bay hills.
Foster City has no real historic centre — it was designed from scratch — but the waterfront trails and lagoon system give it a pleasant, almost resort-like feel for a suburban community. It makes a comfortable base for exploring the Bay Area peninsula, sitting halfway between San Francisco and San Jose.
