If you are feeling adventurous, try visiting the abandoned shipyard at Hunter's Point.
The Hunters Point Naval Shipyard was a United States Navy shipyard in San Francisco, California, located on 638 acres (258 ha) of waterfront at Hunters Point in the southeast corner of the city.

Right on the Bay is this actually very nice and undervisited park. It's very green, actually has functioning benches and BBQ pits, and a small fishing pier. You are also likely to spot windsurfers who come to this windy spot on the Bay.
Historic brewery, built in 1870, now used as a private residence.
A 24-acre (10-hectare) restored wetland at the base of the Hunters Point Power Plant.
A house built to demonstrate cutting-edge environmentally sustainable design. Come see a real implementation of a solar electricity system, a rain collection system, a black(toilet) water treatment system, and more.
Tours of the brewery are available on Friday evenings.
Overlooking Candlestick Park, this park has great panoramic views of the bay, however it's not one of San Francisco's better maintained parks.
