The Bay School campus at 35 Keyes Avenue is located directly across from the Presidio transportation terminal on Lincoln Blvd. The terminal serves the downtown/around-the-park PresidioGo shuttle which is free for students, faculty, and staff upon presentation of Bay School identification. Nearby at Letterman Drive and Presidio Avenue MUNI route #43 can be accessed. At Richardson Avenue and Francisco Street MUNI route #28 and Golden Gate Transit routes serving Marin County can also be accessed. 

The Presidio bus system, PresidiGo, serves the Trans Bay Terminal, BART, and Caltrain and
