From US 101 North (Van Ness Avenue)
When 101-North (Van Ness Avenue) reaches Lombard Street, turn left onto Lombard. Continue west on Lombard toward the Golden Gate Bridge. Move into and stay in the far-left lane. After crossing Broderick Street (which is right after Divisadero), follow the left turn arrow, which means you'll remain on the continuation of Lombard Street instead of veering right onto Richardson. After two blocks you'll enter the Presidio at the Lombard gate.
Once you've entered the Presidio, proceed to a 3-way stop, and turn right onto Lincoln. At the next 4-way stop sign, you'll see the Thoreau Center ahead and to your right – it’s the white complex with twin balconies in front. Don't turn yet - proceed forward until you reach the parking lot entrance, which requires a tight, right-hand turn. If the front lot is full, there is additional parking located behind the Thoreau Center. We are on the second floor.
From the North Bay
Take US 101 South across the Golden Gate Bridge and take the Downtown/Lombard Street exit. Stay in the far right lane. At the third stop light, turn right onto Chestnut Street. Take the next left onto Lyon Street. Take the next right onto Lombard Street and enter the Presidio at the Lombard gate. Follow directions above.
The Presidio is accessible by MUNI (415-673-6864) bus routes 41, 45, 82X, and 30 (from downtown SF/Market Street), 28, 29, and 43 (from other points in the city). Only the 29 and 43 serve the Thoreau Center directly, others require a 5-10 minute walk from near the Lombard Street Presidio Gate. From the North Bay: several Golden Gate Transit (415-923-2000) buses also stop near the Lombard Gate.
