There is a genre of article about free things to do in San Francisco that is really a list of things to do on a Saturday, which is when they are most crowded and least pleasant. The interesting version of the question is what this city gives you for nothing on a Tuesday — because a surprising amount of it is better midweek, some of it is only available midweek, and the whole experience of the place changes when the queue is gone.
Free listings go stale fast and a lot of the good ones are not advertised anywhere. Ask Karpo what is genuinely free and open near you today.
The coast, which is free and never closed
San Francisco's best free asset is its western edge, and it is at its best on a weekday morning. The Lands End trail runs along the cliffs from the Sutro Baths ruins toward the Golden Gate, and on a Tuesday you will pass a handful of people rather than a procession. The Sutro Baths themselves — the concrete skeleton of a Victorian swimming complex that burned down in 1966 — are the strangest free thing in the city and cost nothing to walk around. Further south, Ocean Beach is enormous, usually empty, and reliably colder than you dressed for. None of this is a secret; it is simply that most visitors are downtown on a Tuesday and most residents are at work.
The correct way to do this is early and layered. The marine layer generally burns off in the late morning, so the view you came for often arrives around eleven. If it does not, the fog version is genuinely better than the sunny version, which is something people only accept after living here a while.
The museums and gardens that let you in for nothing
Free admission in San Francisco is a patchwork of resident schemes, monthly free days and a few permanently free institutions, and it repays five minutes of checking. The Cable Car Museum in Nob Hill is free every day and is a genuinely good museum — it houses the working winding machinery that pulls the actual cables under the actual streets, which you can stand above and watch. The San Francisco Botanical Garden and several of the city's major museums run free days and resident-free schemes that are easy to look up and easy to forget. Musée Mécanique down at the waterfront charges nothing to walk in among a hundred antique arcade machines; you only pay if you want to play one.

The public library system is the most under-used free thing in San Francisco. The main branch is a serious building with a serious collection, it is warm, it has power, and on a weekday afternoon it is close to empty. If your Tuesday needs an indoor hour, this is a better answer than a cafe and it costs nothing at all.
Viewpoints, which are all free and mostly unvisited
The city's topography does most of the work. Grand View Park in the Inner Sunset is a short, steep climb to a bare summit with a full sweep from the ocean to downtown, and it is usually empty. Ina Coolbrith Park on Russian Hill is a small terraced garden with one of the best downtown views in the city and almost no signage pointing to it. Bernal Heights, Corona Heights and the Kite Hill area all deliver a similar payoff. On a weekend these have people on them; on a Tuesday afternoon you will frequently have the whole thing to yourself, which is the entire difference between a nice view and a memorable one.
The midweek-only things
A handful of San Francisco's better free experiences are structurally weekday events. City Hall is an operating government building, which means its rotunda and its staircase — one of the most photographed interiors in the city — are open to walk into on weekdays and shut at weekends. The same logic applies to the lobbies of several downtown towers with publicly accessible art and atria, which exist because of planning agreements and are open during office hours only. Farmers markets run midweek as well as at weekends, and the weekday ones are smaller, cheaper and far easier to move through.
The general principle is that a large part of San Francisco is a working city with public spaces attached, and those spaces follow office hours rather than tourist hours. If your mental model of free things here is parks and beaches, you are missing roughly half of them.
The murals, which are free and genuinely world-class
San Francisco has one of the best collections of public mural art in the United States and charges nothing for any of it. The Mission's alleys — Balmy Alley and Clarion Alley in particular — are dense, constantly repainted and best seen on a weekday when you can actually stand in front of a wall without moving for someone. The city also holds several Diego Rivera frescoes, painted during his time here in the 1930s and 40s, which sit in working buildings rather than museums and can be visited free during business hours. That is a genuinely unusual thing to be able to do with a major twentieth-century artist, and almost nobody does it.
The same is true of Coit Tower's interior murals, painted in 1934 by a group of local artists as a public works project, which are visible in the ground-floor lobby for nothing — you only pay if you want the lift to the top. Given that the view from Telegraph Hill outside the tower is free and nearly as good, the lobby-only visit is the better value by a wide margin.
Building an actual Tuesday out of this
A version that works: start on the coast while it is quiet, walk the Lands End trail and come out at the Sutro Baths, then cut inland and up to a viewpoint while the light is still flat. Take a free museum or the library through the middle of the day when energy drops. Finish downtown in the late afternoon so you can walk into City Hall or a tower lobby before they close at five. That is a full day, it involves no admission charges at all, and the only real cost is transport. The version of the same day on a Saturday costs the same and is roughly half as good, which is an unusual thing to be able to say about anything.
