The free-museum-Tuesday thing is real, and it is also the smallest part of the story. Several major San Francisco museums waive admission on the first Tuesday of the month, which is excellent if the first Tuesday happens to be the day you are free and irrelevant the other thirty. The list worth carrying around is the one that never charges at all — and in this city that list includes some of the genuinely best things to do.
Free does not mean open, and half of these keep hours that catch people out. Ask Karpo which of them is open right now, what the weather is doing on that side of the city, and how to string three of them together on one trip.
The Presidio is the biggest free thing in San Francisco
Tunnel Tops opened in 2022 on top of the highway tunnels between the main post and Crissy Field: fourteen acres of new parkland with the bridge on one side, the bay in front and an outdoor play area built into the landscape. It costs nothing, it is open daily, and it is the single best introduction to the city you can give a visitor.
The rest of the Presidio runs on the same terms. Andy Goldsworthy has four installations scattered through the forest — Spire, Wood Line, Tree Fall and Earth Wall — and finding them is a proper afternoon's walk. Fort Point sits underneath the south anchorage of the Golden Gate Bridge, a Civil War-era brick fortress with the bridge directly overhead, and admission is free on the days it opens.

Two museums that never charge
The Cable Car Museum on Mason Street is not a museum about cable cars so much as the actual powerhouse: the winding machinery that pulls every cable in the system runs on the floor below you while you watch. It is free, it is loud, and it takes twenty minutes or an hour depending on how interested you get.
Musée Mécanique on Fisherman's Wharf charges nothing at the door — it is a warehouse of antique arcade machines, fortune tellers and player pianos, and you pay only the coins you feed into whichever one you want to see move. Bring quarters. The Randall Museum on Corona Heights is the third: free admission, a hilltop location with one of the better city views, and a building full of hands-on science and art rooms.
The walks that are the actual attractions
Lands End runs along the northwest corner of the city, past the ruins of the Sutro Baths and a stone labyrinth built on the bluff above the water. Golden Gate Park is 1,017 acres and contains an AIDS Memorial Grove, a bison paddock and a Dutch windmill, none of which cost anything. The 16th Avenue Tiled Steps in the Sunset are a 163-step mosaic that people fly here to photograph; you can climb them any time and keep going up to Grand View Park, where the view earns the walk.
In the Mission, Balmy Alley and Clarion Alley are open-air galleries of political mural work going back to the 1970s, repainted continuously by the artists who live around them. Downtown, Salesforce Park sits five storeys above the street on the roof of the transit centre — over five acres of gardens, free, with a free gondola up.
There is a whole second tier of these hiding in plain sight. The Wave Organ, out at the end of the Marina jetty, is a sound sculpture built from demolished cemetery stone that plays the tide through a set of pipes — go at high water or it does nothing. The Seward Street Slides in the Castro are two concrete chutes on a hillside that anyone can ride with a piece of cardboard. Neither has a ticket booth, an opening ceremony or a queue, and both are more memorable than most things people pay for here.
The free hours inside paid places
This is where a little knowledge pays. SFMOMA's ground floor galleries can be entered without a ticket. The Japanese Tea Garden in Golden Gate Park is free before 10am on several mornings a week, which is also the only time it is quiet. San Francisco Botanical Garden is free to city residents with proof of address. City Hall is a working government building that anyone can walk into on a weekday, and the rotunda is one of the great interiors in the western United States. Coit Tower's ground-floor murals — 1930s Depression-era frescoes — are free to look at; only the elevator to the top costs money.
How the free-day system actually works
First Tuesdays vary by institution and change without much fanfare, so confirm before you build a day on one. Several museums also run free admission for young people up to a certain age, free days tied to specific communities or neighborhoods, and library pass programmes — the San Francisco Public Library lends museum passes, which is the least-used good idea in the city. And free days are busy days: the trade for the ticket price is a crowd, so if you dislike queues, one of the always-free options above will give you a better afternoon.
Practical notes
Check hours rather than assuming; Fort Point in particular opens only on certain days of the week, and the Randall closes on Mondays. Weather decides everything on this list — Lands End in fog is atmospheric, Lands End in wind is unpleasant, and the two look identical in a forecast for 'San Francisco'. The Presidio and Golden Gate Park are both large enough that a bus or a bike changes the day materially. Bring quarters for the Musée. And if you are visiting with a resident, have them bring ID for the Botanical Garden gate.

Ask Karpo first
Want to know which of these is open right now, whether the fog has taken the view on that side of town, and how to link three of them without crossing the city twice? Ask Karpo for today's hours, the weather where you are going and a route that fits the afternoon you have.
