Take exit on 101 South AFTER Blithedale Avenue (Mill Valley) exit. Please note: there is no signage for the exit. (It is the exit you would use to get off to go to Arco Gas Station or Goodman’s Hardware.) Follow Redwood Hwy Frontage Road, take the first right at Hamilton Drive (Big Shelter Bay Office Complex Sign), then turn left onto Shelter Bay Avenue, take road to end (jogs to left) and park in public parking. Walk to shoreline.  Nice walkway on water’s edge with spectacular views of Mt. Tams.
