A Swim at Aquatic Park in San Francisco
The cool, often flat water of Aquatic Park is an accessible option for open water swimming in San Francisco.
Within site of tourist meccas Fisherman’s Wharf and Ghiradelli Chocolate Experience, you can have an uncrowded San Francisco open water swimming experience at Aquatic Park.
Typically cool water for Summer (San Francisco bay water temperature ~57F/14C) and air (about the same) kept the tourists and most everybody else not only out of the water but away from the small beach on the two July days I visited.
But a small crowd of regulars and I did manage a swim: the sheltered cove provided water that was mostly flat, a swimming area well marked by buoys, and an easy sand beach entry and exit.
Aquatic Park bleachers were a convenient spot to organize gear and stuff belongings into an open water swim buoy (me) or store it under the watchful eye of a friend (the regulars).
