Directions & Map

The Department of Cardiothoracic Surgery is located in the Falk Building located behind the hospital on the Stanford campus in Palo Alto, California. San Francisco is to the north, and San Jose is to the south. Two main north-south freeways link us to San Francisco, San Jose, and their airports: US Highway 101 and Interstate 280. Shuttle and bus service to Stanford is available from nearby airports. A commuter rail line, Caltrain, also connects the Peninsula. Stanford's free Marguerite Shuttle connects with Caltrain and downtown Palo Alto.

The map below shows the location of both the Falk Building and the Visitor Parking Structure that is most accessible to Falk (the Falk Building does not have its own visitor parking). Parking fees are listed below.

More information on Stanford Hospital parking.

It's best to map your route to the Visitor Parking Structure, then walk or take the free shuttle to the main entrance to the hospital.

Enter the hospital, turn left, then make a right through the cafeteria seating area. Once outside of the seating area, there’s a hallway that goes left.

Walk down this hallway, past the Emergency Room, all the way to the end, and you will find several doors to your right that lead outside. Go through these doors. (Note: These doors will lock behind you, so if you need to go back this way, have someone from the Falk building use their security card to let you back in.)

Make a left on the path, then the first right into the Falk Building.
