If it’s a sunny day and you want to hang with the locals, head to this hilly 16-acre park. Blanketed with lush green lawns and dotted with palm trees, a soccer field, tennis courts, a basketball court, a playground, and great views, it can be quite the scene of modern bohemia, with picnickers lounging on blankets covering nearly every open patch of grass and the occasional beloved marijuana-edibles dealer happily offering goods at cash prices. It’s a fantastic place to relax and take in good San Francisco vibes. And with lots of great food to be found along 18th street, a picnic can be thrown together in a snap.
