You can do the de Young with the city pass, but we elected to pay for this one and use the ticket for the Exploratorium instead. We were able to get deeply discounted tickets since we are members of the Denver Art Museum. This museum is gigantic. Make sure to take the elevator up to the tower for views over Golden Gate Park and the rest of the city. They will have special exhibits, but expect to pay more for those. We were on a time crunch, so did a quick run through of the place. I really enjoyed all the masks and ceremonial art from Africa.
