I have spent too much time wandering the streets of San Francisco to care about how visitors spend their time effectively, efficiently and cheerfully while on limited schedules traveling from near and far. From amazing architecture, beautiful street art, quirky fixtures, beautiful alleys, charming Victorians, stunning views, institutional businesses and everything in between. Here is my definitive San Francisco essentials list for tourists, professional travelers, insiders and those with permanent sense of wanderlust. While in town, check out the EaterSF Essential 38 restaurant list (do not listen to Michael Bauer of SFGate / SFChronicle). Follow VisitMarin, VisitCalifornia, OnlyInSF Instagram handles too. My favorite neighborhoods to explore are Mission District, Hayes Valley, Financial District, Castro, Nopa, Presidio, Embarcadero and North Beach/Jackson Square. As for day and weekend trips, check out Marin Headlands, Lake Tahoe, Yosemite, Big Sur, Sonoma/Napa as well as West Marin Hwy 1.
