The two swimming clubs situated at Aquatic Park on San Francisco Bay are The Dolphin Club ( http://www.dolphinclub.org/about.html ) and The South End Club ( http://www.south-end.org/club.shtml ). Both date back to the 1870s, and were formed as both rowing and swimming clubs. Members swim in the Bay all year round
The clubs are open to the public on alternate days, excluding Sundays and Mondays. Previously, both last year and this year too, I'd been for a swim on days when it was the Dolphin Club that was open for public swimming. I was lucky enough on my fifth swim in San Francisco Bay to swim from the South End Club.
