The California Academy of Sciences states it cannot permit any child under 4 into the Morrison Planetarium, so a third of that ticket is closed to a toddler. Under-5s ride the cable car free while everyone from 5 pays the full 9 dollars, and youth 18 and under ride all regular Muni free. Presidio Tunnel Tops, the Cable Car Museum and the Randall Museum are free, unticketed and the best fit for an unpredictable day.
In Brief
What should we actually do in San Francisco with a toddler?
Lead with the free and unticketed things, because with a toddler the ability to leave after forty minutes is worth more than the attraction. Presidio Tunnel Tops has the best playground in the city and costs nothing. The Children's Creativity Museum is the one paid venue built for exactly this age, from one year old. Think twice about the Academy of Sciences: it is excellent and it bars under-4s from the planetarium, so you are paying full price for two thirds of it.
Key takeaways
- The Academy of Sciences cannot permit any child under 4 into the planetarium, in its own words
- Under-5s ride the cable car free, and everyone aged 5 and over pays the full 9 dollars
- San Francisco Zoo is the only venue here publishing a stroller price, at 15 dollars single and 18 double
- The Japanese Tea Garden publishes that most of its historic landscape is not step-free
The 14 things worth doing, easiest first
Ordered by how well each fits a toddler's day rather than by how famous it is. The three things that decide it at this age are whether you can leave whenever you like, whether there is somewhere safe to put a child down, and whether a nap wrecks the booking. Anything timed or ticketed drops down the list for that reason alone.

Sloat Boulevard, at the ocean end of the city
San Francisco Zoo and Gardens
Rated 4.4 out of 5 on Google Maps from 14,435 reviews, as of October 2026The city zoo, whose Elinor Friend Playground is split into three named bio-regions with published age bands, starting with a River Play Area for six months to two years.

- Cost
- 32 dollars weekdays and 34 at weekends for an adult, 22 and 24 for a child aged 2 to 11.

Directly under the south end of the Golden Gate Bridge
Fort Point National Historic Site
Rated 4.8 out of 5 on Google Maps from 4,211 reviews, as of October 2026A Civil War brick fort tucked under the bridge, free to enter, with three roofed tiers and the bridge directly overhead.

- 45 minutes to 1.5 hours
- Ages
- The fort itself lands from about 4. For a toddler the value is the bridge overhead
- Cost

- Cost
- 9 dollars a single ride with no transfers, for everyone aged 5 and over. Under-5s ride free.

The entrance to Pier 39
Aquarium of the Bay
Rated 4.1 out of 5 on Google Maps from 6,469 reviews, as of October 2026Walk-through tunnels under the bay's own water, which is a short, dark, immediate experience that suits a small child better than a large aquarium would.

- 1 to 1.5 hours
- Ages
- 2 to 8. The tunnels are the whole appeal and they work from about 2
- Cost
- 28.25 dollars at the gate for an adult and 20.25 for a child aged 4 to 12. Online pricing is date-based and runs higher than the gate.

- If it rains
- If it rains: It is itself the indoor option at Pier 39.
Pier 15, the Embarcadero

Rated 4.7 out of 5 on Google Maps from 8,763 reviews, as of October 2026The city's science museum, built on hands-on exhibits, and the best indoor day in San Francisco for a school-age child.

- 3 to 4 hours for a full visit, and far less with a toddler
- Ages

- 39.95 dollars for an adult aged 18 to 64 and 29.95 for youth aged 4 to 17. Children 3 and under are free.
- Booking ahead
- Not timed, which helps. Closed Mondays, opens at noon on Sundays, and the Thursday evening session is 18 and over.
- If it rains
- If it rains: It is itself the indoor answer for the Embarcadero.
Music Concourse, Golden Gate Park
California Academy of Sciences
Rated 4.6 out of 5 on Google Maps from 6,447 reviews, as of October 2026An aquarium, planetarium, rainforest dome and natural history museum under one living roof, and the most complete indoor day in the city.
A solid half day- Time needed
- 3 to 5 hours for a full visit
- Ages
- From about 4, and that number is set by the operator rather than by us
- Cost
- 49 dollars off-peak and 55 peak for an adult aged 19 and over, and 39 off-peak and 45 peak for a child aged 3 to 12. Youth aged 13 to 18 are a separate band at 45 and 49.
- Booking ahead
- Book, and read the planetarium rule first. The Academy states it cannot permit any child under 4 into the Morrison Planetarium, and that shows may not suit under-7s, so with a toddler you are paying full price for two thirds of the building.
- If it rains
- If it rains: It is itself the indoor answer for Golden Gate Park.
Golden Gate Park, beside the Music Concourse
Japanese Tea Garden
Rated 4.5 out of 5 on Google Maps from 17,010 reviews, as of October 2026The oldest public Japanese garden in the United States, with a koi pond, a drum bridge and a tea house, immediately beside the Academy of Sciences.
A solid half day- Time needed
- 45 minutes to an hour
- Ages
- From about 4. Under that it is the koi pond and the bridge and nothing else
- Cost
- Prices sit inside a booking widget that could not be read, so none is published here. The garden is free from 09:00 to 10:00 on Mondays, Wednesdays and Fridays.
- Booking ahead
- Use the free morning window if you can. The operator publishes that most of the historic landscape is not step-free, which with a pushchair is the deciding fact.
- If it rains
- If it rains: The Academy of Sciences and the de Young are both on the same concourse.
What parents ask about San Francisco
Can a toddler go into the planetarium at the Academy of Sciences?
No, and the Academy says so itself rather than leaving you to find out at the door. It publishes that it cannot permit any child under 4 into the Morrison Planetarium, and separately that shows may not be appropriate for children under 7. That matters more than it sounds, because the planetarium is one of the four things the ticket buys alongside the aquarium, the rainforest dome and the natural history halls. With a one to four year old you are paying 49 to 55 dollars an adult for roughly two thirds of the building, which is still a good day, but it should be a decision rather than a surprise.
Do toddlers travel free in San Francisco?
Mostly, and the free line sits in two different places depending on what you board. On Muni, youth aged 18 and under ride free on all regular service, with the cable car excepted. On the cable car itself, only children aged 4 and under ride free and everyone from 5 pays the full 9 dollars a ride, with no transfers. BART is the same shape, free for children 4 and under. The Sausalito ferry also draws its free line at 4 and under. So a toddler is the cheapest passenger in the city on precisely the routes where an older child is the most expensive.
Which San Francisco attractions have changing facilities?
Almost none of them will tell you, which is its own answer. Of fourteen venues checked on their own sites, the Bay Area Discovery Museum is the only one publishing proper detail about changing tables and family facilities, and the Presidio publishes restroom locations at the Transit Center. Everywhere else, including both children's museums and the Academy of Sciences, publishes nothing at all. The practical consequence is to favour the free unticketed places with a very small child, because leaving and coming back costs you nothing there.
Getting around with children
Muni is free for anyone 18 and under, which removes most of the transport cost of a family day, and the exception is the cable car, where the free band stops at 4 and a single ride is 9 dollars with no transfers. BART and the Sausalito ferry both draw their free line at 4 and under too. The hills are the real constraint rather than the fares: with a pushchair the flat routes along the Embarcadero and through the Presidio are a different city from Nob Hill, and the Powell and Market cable car queue has no seating, so board at a stop further along the line if you board at all. For the Bay Area Discovery Museum, take the ferry rather than driving, because the crossing is the part a toddler enjoys.
Where to base yourself in San Francisco
Stay somewhere flat if the child is in a pushchair, which in practice means the Embarcadero, Yerba Buena or the Marina rather than Nob Hill or Russian Hill. Yerba Buena is the strongest single base at this age: the carousel, the playground and the Children's Creativity Museum are all in one block, and the Exploratorium is a level walk along the water.

What to skip
Three things to plan around. The Academy of Sciences bars under-4s from the planetarium outright, so read that before paying peak-season prices. The Japanese Tea Garden publishes that most of its historic landscape is not step-free, which makes it a poor choice with a pushchair however beautiful it is, though the free 09:00 to 10:00 window on Mondays, Wednesdays and Fridays is worth knowing. And check opening days rather than hours: the Children's Creativity Museum is closed Monday and Tuesday, the Cable Car Museum closes Mondays, the Randall Museum closes Sunday and Monday, Fort Point is shut Tuesday and Wednesday, and the Presidio Field Station only opens Wednesday to Sunday. A toddler day built around a closed door is a wasted morning.
