Walk up (or down) the iconic tiled steps in SF.
These tiles steps are ironically iconic, as they are called the "Hidden" Garden Steps. They are one of 3 tiled staircases that San Francisco is famous for. The others are the 16th Ave Tiled Steps and the Lincoln Park Steps.
Tip: When calling an uber, try to get dropped off at the top of the steps and picked up from the bottom.
