Sit in the park and view the facade of where the iconic 80s and 90s show full house was filmed.
You can recreate the photo from one of the opening scenes in the show where the "Full House" crew are picnicing in the Alamo Square park out the front of the house on a hot sunny day. The Alamo square park is quite nice aside from seeing the full house houses, atop a hill it gets a good amount of sun and offers panoramic views of San Francisco. To recreate the full full house experience you could rent a red convertible and head across the golden gate bridge.
Expect to see a few people at the painted ladies if you head this way as it's definitely not a unique attraction to San Francisco but is an integral part to the trip and something you can do.
