From Northbound 101 :
Take the Shoreline exit (Hwy 1/Mill Valley/Stinson Beach) and continue straight at all
stoplights on Shoreline, Almonte, and Miller into downtown Mill Valley.
Miller splits into two one-way streets, and the last block
(between Sunnyside and Throckmorton) is a small parking area.
Go through the parking area and turn left on Throckmorton.
Continue on Throckmorton to Olive; the church is in a redwood grove
at the right-hand corner of Olive and Throckmorton.
There's plenty of street parking.
From Southbound 101 and the East Bay: Take the E. Blithedale/Tiburon exit; turn right on E. Blithedale and go about 2 miles into downtown Mill Valley. Turn left on Throckmorton and left at the junction with Corte Madera Avenue. Take Throckmorton to Olive as above.
NOTE The exit onto East Blithedale from southbound 101 may be closed periodically for construction. If it is continue to the Hwy 1 exit, turn left at the light onto Shoreline and continue as with the Northbound 101 directions.
