A great natural harbor, from the first years of its European discovery the Golden Gate became known as a pivotal access point to the American West. Trade and military strategy aside, The Bay is California’s most important ecological treasure. A natural nursery for crab, halibut, waterfowl, seals and sea lions, as well as endangered species, the San Francisco Bay provides a great ecological treasure to residents and visitors alike. Whale watching, ferrying out to Alcatraz and Marin, or simple sunset tours with the glistening Golden Gate Bridge are favorite pastimes, while residents simply feel assured looking out of their windows and knowing that its calm waters are there.
