Sunday, June 7, the Ferry Building on the Embarcadero hosts Juneteenth on the Waterfront, the sixth annual edition of a free, all-day celebration of Black-owned businesses with food, crafts, and live programming, organized by Foodwise. Free entry. It runs alongside two other reasons to be at the same spot: the HEAD WEST Marketplace (11am–5pm), a pop-up of local makers, ceramics, and sourced vintage, and the tail end of the Ferry Plaza Farmers Market (Saturday is the big market day; Sunday is lighter but open in the morning). Bring cash for vendors.

Here's the catch you need to know before you go: BART is single-tracking through the Transbay Tube all day Sunday for lighting work. Only the Blue, Yellow, and Orange lines run — no Red or Green Line service — and trains come every 30 minutes systemwide instead of the usual frequency. Embarcadero Station still gets you to the door via the Blue and Yellow lines, but build in a buffer and check bart.gov before you leave. If you're coming from the East Bay, that half-hour headway is the difference between catching the event fresh and standing on a platform.

Want more than the waterfront? It's the first Sunday of the month, so the Asian Art Museum (200 Larkin, Civic Center BART) is free, 10am–5pm.

If you've got two hours: Take BART to Embarcadero, hit Juneteenth on the Waterfront first while the food's hot, loop through HEAD WEST for the makers, then walk the Embarcadero promenade rather than waiting on a return train — the 30-minute headway makes a stroll the smarter move.
