San Francisco is known for offering free admission and special discounts about town so that everyone has a chance to visit the cultural gems of the city. Golden Gate Park is no exception, as you’ll find a handful of free days at two of the most popular attractions in San Francisco: the de Young Museum and the California Academy of Sciences. Get your calendar ready, so you can mark down the following dates:

de Young Museum
50 Hagiwara Tea Garden Drive

The first Tuesday of every month means free admission to the de Young Museum – home of paintings, sculpture, textiles, and other decorative pieces of art. Also, if you own a Bank of America ATM, check or credit card, you can enjoy free general admission to selected Bay Area museums, and de Young happens to be one on the list. For the first weekend of every month, present your card and gain access to a wealth of scientific exploration.

California Academy of Sciences
55 Music Concourse Drive

Visit the California Academy of Sciences on every third Wednesday to enjoy free admission to a museum that houses an aquarium, a planetarium, a natural history museum, and many curious-looking critters under one sustainable living roof. The free entry comes courtesy of the Bernard Osher Foundation, and admission is on a first come, first served basis.

The California Academy of Sciences also offers free admission on Neighborhood Free Days, where designated days are given to residents of various neighborhoods in San Francisco. This event usually occurs two times per year – in the spring and again in the fall. To take advantage of this opportunity, don’t forget to bring a form of identification, such as a driver’s license, utility bill, or even a magazine label with name and date. It is also advised to arrive early, as Free Days usually draws in a large crowd.

From time to time, the Academy also offers free admission to military personnel, firefighters, police officers, and teachers.
