The fourth Saturday of each month from May through August, Occidental Flea Market sets up in the Outer Sunset. Hours and exact address are on SFFuncheap's listing — confirm before you go, since outdoor markets shift. No BART direct; the N-Judah to Irving gets you close, or park on a residential side street off Noriega rather than circling the main drag.

This is a neighborhood-scale flea, not a stadium-sized swap meet. That means fewer booths, faster laps, and a higher chance you're buying something from the person who actually owned it. The May–August window keeps the crowds rotating — different vendors show up across the season, so a return trip in July isn't the same market you walked in June. Food situation depends on the date; bring cash for both goods and any nearby taquerias.

If you've got two hours, get there within the first 30 minutes of opening — the better finds move fast at a market this size — then walk west to the beach after.
