In this section, we will cover each of the discount opportunities available for tickets to the California Academy of Sciences, including tourist passes, combo packages, and other deals.

Tourist Attraction Discount Passes

If you’re planning to visit a lot of notable locations while you’re in San Francisco, a tourist pass could easily help you save a lot of money on several popular activities.

The California Academy of Sciences is included in several different tourist passes.

Depending on which pass you choose, you could save anywhere from 15% - 50% or more off general admission prices.



Some of these services provide access to dozens of attractions over the course of 1, 2, 3, or 5 days. Others offer a specific selection of activities for one flat price.

There is also a build-your-own pass which essentially works as a basic discount service – all you have to do is purchase a ticket for two separate tours or attractions in order to get 20% off for each!

Check this list of additional attractions included with these passes for other locations you plan to visit so that you can save even more money on tickets:

  • Exploratorium
  • de Young Museum
  • Madame Tussauds
  • Aquarium of the Bay
  • Ripley's Believe it or Not
  • Walt Disney Family Museum
  • San Francisco Zoo & Gardens
  • San Francisco Museum of Modern Art
  • And more!

If you are interested in even a few of these activities, using a tourist pass to pay for admission to all of them could save you a lot of money.

Here are the various pass options and the savings you can expect:

Many of these passes include skip-the-line privileges at certain popular locations in the San Francisco area.

For more details, make sure to read our full post covering San Francisco tourist attraction discount passes.

Combo Packages

There is currently only one notable combo deal which includes admission to the California Academy of Sciences.

This package features a 1-day hop-on-hop-off bus tour in addition to the museum ticket. 

The main advantage of this combo package is that you won’t have to purchase two individual tickets.

That said, you could potentially save more by using a tourist pass instead.

For the sake of comparison, a 1-Day Go San Francisco Pass includes a hop-on-hop-off bus tour, admission to the California Academy of Sciences, and dozens of other attractions for only $92.

If you want to enjoy more than just these two activities, this pass would give you access to several additional services for only $2 more than the combo package!

Free Days

San Francisco residents can get free admission to the California Academy of Sciences during one weekend every year.

The date of each free weekend depends on which neighborhood you live in.

Learn more about Neighborhood Free Weekends.

Similarly, if you hold a library card at certain Bay Area libraries, you may be eligible for the Discover & Go program which allows you to “check out” a pass which is good for museum admission for one adult and one youth.

Learn more about the Discover & Go library program.
