Woodward's Gardens (1861 to 1891) was amusement park, zoo, museum, aquarium, botanical garden, and art gallery all in one. Thousands of patrons would flock to the two-block locale bordered by Mission, Valencia, 13th and 15th Streets. Probably the most famous resident there was Monarch the Grizzly Bear, who became the model for the California state flag. (via San Francisco Public Library)

This 1899 map shows the now-defunct Steeplechase Park (1899 to 1906). Located at 8th and Market Streets, it was owned by George Silyou, the same man who owned Coney Island's park of the same name. For 10 cents admission, you could check out the high-wire walker known as Professor Hill, ride on a wooden horse for prizes, get on the aerial trolley, or check out a boxing match at the Edison motion picture theater.

The Sutro Baths was the world's largest indoor swimming pool when it opened in 1896.

Starting in the 1800s, outdoor attractions were slowly starting to take up the space next to Ocean Beach. By the 1920s, the collection of amusements—including the ferris wheel, the chutes, and the Big Dipper roller coaster—were called Chutes at the Beach. In 1929, it became Whitney's at the Beach, better known as Playland at the Beach. (via SFGate)

There were even chutes in the Haight. Opened in 1895, Paul Boynton Chute Company's amusement park—situated between between Cole and Clayton Streets—had an inclined trestle track 300 feet long and 70 feet high that took passengers down in gondolas to an artificial lake. There was also a merry-go-round, an alligator house, and theater at the park. (viaThe Friends of 1800)

The Chutes at 10th Avenue and Fulton Street (1902 to 1907) were opened to accommodate the overflow crowd from the popular Chutes on Haight. The facility was moved here, and then to Fillmore in 1909. An apartment building stands in the space today. (via FoundSF)

Before there was Disneyland or Six Flags, there was Playland at the Beach (pictured here in 1940), which later became known as Whitney's at the Beach. Playland closed in 1972; a plaque sits in the former location of the amusement park, where condominiums now stand. (via Quill Driver Books/San Francisco Public Library)

A dip in the chilly waters of Ocean Beach, or just a day on the sand, has always been in vogue, even in 1920. (via Western Neighborhoods Project)
