The “Speed Run” Itinerary: What to Do in 8 hrs 15 mins
You have a Green Light. This means you have enough buffer to take the BART into the city and actually enjoy yourself without checking your watch every thirty seconds.
- Step 1: Drop your luggage immediately at the Airport Travel Agency (Intl Terminal). You cannot speed run the city dragging a suitcase.
- Step 2: Hop on the BART express train. Take it all the way to Paddington Station.
- Step 3: Walk straight to Ferry Building Marketplace. This is the icon of the waterfront. Snap the photo, smell the sourdough, and soak in the atmosphere.
- Step 4: Stroll along the Embarcadero to see the Cupid’s Span Sculpture. It offers a fantastic angle of the Bay Bridge for your Instagram story.
- Step 5: You’ve likely worked up an appetite. Grab a world-class meal at Hog Island Oyster Co. (Ferry Bldg) located right in the marketplace.
- Step 6: Head back to the station. Do not push your luck; aim to be on the train well before your buffer time starts.
