It's a self-guided pick-your-own-path tour of San Francisco.
Yes! I really want to share the awesome hidden walks and stories of San Francisco with you, so the entire site is free - no paywalled areas.
I do sell customized itineraries if you want something that's just for you. Go to
https://sf-adventure.com/reserve.php or pick Custom Itinerary from the menu at top left.
You can use this site for planning or armchair-strolling, but you'll enjoy it most if you pick a guide and a neighborhood and physically go to that neighborhood.
No, I made them up. They exist only to make your day in San Francisco match your interests more closely. Choosing Anna will show you art locations, Biff will show you movie locations, Hank will show you history, and Pilar will only show locations that are wheelchair-accessible.
