Spend the afternoon at Dolores Park in the Mission.
The Mission is a fun and hip neighborhood packed with a variety of great restaurants, bars, boutique shops, and attractions. It's most famous for its murals, as well as Dolores Park where locals flood to on sunny days. You can easily spend the day in this area, but if you find yourself running out of things to do, check out The Castro, which is a short walk away. You won't be able to miss the LGBTQ-friendly area with its waving rainbow flags and painted streets.
