Top 25 Free Things to Do in San Francisco

                                                                  BEACHES

The water is cold year round, but don’t let that stop you from heading to the bay. The city offers a number of outstanding beaches: Ocean Beach on the Western edge of town for watching surfers and sunsets; Baker Beach for amazing views of the Golden Gate Bridge; and the Marin Headlands, the coastal trail, and Aquatic Park where you can watch Dolphin Club swimmers and see plenty of boats in the harbor.
The nearby Hyde Street Pier is great for views of the city and the bay. Aquatic Park is an urban beach, part of the Maritime Park Association and home to the Maritime Museum in the Aquatic Park Bathhouse Building. This classic art deco building resembles an ocean liner, and it’s free to check out the murals in the lobby and the views from the veranda.
