Porchfest is the neighborhood-crawl concert format where local musicians play front porches and stoops — free to walk, bring cash for whatever the hosts are selling. Pride Month kickoffs vary by venue but generally cluster around bars and community spaces in the Castro and SoMa; look for free entry early in the evening, cover charges after 9pm. The Presidio beer festival is ticketed — check the Presidio Trust site for remaining availability and the $40–$60 price range. The Chinatown museum opening is the fresh entry here: a new cultural institution on a block that doesn't get enough foot traffic, worth the detour even if you only do a lap.

For the Presidio event, Crissy Field parking fills fast on weekends — take the PresidiGo shuttle from the Transbay Transit Center or walk in from the Lombard Street Gate. For Chinatown, park in the Portsmouth Square Garage on Kearny; it's cheaper than anything on Grant Avenue and you're two blocks from everything.

If you have two hours: hit the Chinatown museum opening first (it's new, it'll be crowded later in the month), then walk to a Porchfest block if one is still running nearby. That's a full afternoon on foot with no ticket required.
