San Francisco with Kids on a Budget: What a Family Outing Costs

A low-cost day in San Francisco starts with one decision: what will the whole family spend on the main activity? A free playground, a $7 carousel stop, and a $40 boat rental can all make a good afternoon, but they need different budgets.

The comparison above uses two adults ages 19–64 and two children ages 6 and 10. Prices were checked September 8, 2026. These are published admission or activity costs; add transport, food, parking, and any booking charges shown at checkout. Change the ages and group size before using the totals for your family.

For a longer list of places with no admission charge, use our free things to do with kids in San Francisco guide. This page helps you choose where a little spending is useful and how to keep the rest of the day affordable.

Start with the cost of getting there

Children 18 and under ride Muni free. That includes buses, Metro, and historic streetcars, regardless of residency or income. It does not automatically cover cable cars, BART, or ferries. Children do not need a Clipper card for the free Muni program.

For adults, the published single-ride fare is $2.85 with Clipper or a contactless bank card, or $3 cash. The fare includes transfers within 120 minutes. A $5.70 Muni-only Day Pass covers buses, trains, and historic streetcars until 11:59 PM; cable cars are excluded. Two adult day passes cost $11.40, with the children in our example riding free.

Use the day-pass figure when you need travel spread across the day. A short outing within one transfer window, walking, or an existing pass may cost less. If you drive, look up parking for the actual destination and time; free admission does not make parking free.

Outings with a small, predictable activity bill

Koret Playground and one carousel ride: $7 for four

Koret Playground is free. The adjacent carousel lists adults at $2.50 and children ages 6–12 at $1 per ride, so one ride each for our example family is $2.50 + $2.50 + $1 + $1 = $7. Decide on the number of rides before joining the line.

Children 5 and under ride free with a paying adult; children under 40 inches must have a paying adult accompany them. Carousel hours depend on weather, school schedules, and season. Check the operator's current message before promising a ride.

Randall Museum: $0 admission

Randall Museum is a useful indoor choice when you want museum time without buying four tickets. General admission is free, Tuesday through Saturday, 10 AM–5 PM. Classes and separately scheduled programs may have fees; a free museum visit does not include every activity on the calendar.

Public recreation swim: $20 for four

SF Recreation and Parks' fee sheet, effective July 1, 2026, lists recreation and lap-swim drop-in admission at $8 for adults ages 18–64 and $2 for children ages 0–17. Our family total is $8 + $8 + $2 + $2 = $20.

Choose a recreation-swim session from the official pool schedules ↗, then check that pool's closures, child-supervision rules, and entry requirements. A building's open hours or a lap-swim slot does not guarantee family play time. Drop-in payment is accepted by exact cash or credit card; lessons are a separate purchase.

Check museum discounts before buying regular tickets

California Academy of Sciences: $20 for four with a valid EBT card

The Academy's Museums for All program ↗ offers $5 daytime admission per person for up to four people per visit with a valid EBT card. You can buy online through the program's card-verification process or at the museum ticket window. Four qualifying tickets total $20. Use the program's instructions before starting a full-price checkout.

Exploratorium: $20 for four with qualifying documentation

The Exploratorium's reduced-admission program ↗ offers $5 tickets for up to four people. Accepted documents include EBT/SNAP/CalFresh, Medi-Cal, WIC, or Lifeline Pass, with matching photo ID. Buy these tickets onsite; they are not sold online. P-EBT and EBT Sun Bucks are excluded. Choose daytime admission for a family visit; After Dark is for adults 18 and older.

SFMOMA: free family dates, with advance planning

Guests 18 and younger always receive free general admission. On a Free Family Day ↗, up to two adults accompanying a child or teen 18 or younger also receive free general admission. The next date listed when checked was October 25, 2026; tickets become available two weeks beforehand. Surcharged exhibitions need separate paid tickets. Check the current calendar before planning around a date.

Use your library card before choosing a paid day

SFPL's Discover & Go ↗ provides attraction passes for eligible San Francisco resident library-card holders, subject to availability and each venue's terms. You can hold two active reservations and book up to three months ahead; new dates are released on the first of the month. Read the pass's adult and child allowances before treating it as admission for your whole family. Once printed or downloaded, a pass cannot be canceled.

Two boat outings to price honestly

Blue Heron Lake: $40 for a four-person pedal boat

A Blue Heron Lake pedal boat costs $40 per hour and holds up to four people, subject to a 650-pound combined weight limit. Rentals are first come, first served. The $28 rowboat has a three-person limit, so it does not fit our example family in one boat.

Life jackets must be worn. Follow the operator's adult-accompaniment rules, keep food for your picnic, and watch wildlife without feeding it. Check current rental hours before traveling. A lake walk can be the free part of the outing; the boat is the paid activity.

Golden Gate Ferry to Sausalito: $62 round trip for this family

For the Golden Gate Ferry to Sausalito, the current one-way adult fare is $8.50 with Clipper or a contactless bank card, compared with $14 for an adult paper ticket. Youth ages 5–18 pay $7 each way. Our round trip is (2 × $8.50 + 2 × $7) × 2 = $62. Buying adult paper tickets instead raises that family total to $84.

Each paying passenger needs their own accepted ticket or payment method; a bank-card tap charges the adult fare. Arrange youth fares for the children. Children 4 and under ride free, limited to two per full-fare adult. Choose the outbound and return sailings together and budget separately for lunch and any connecting transport. These prices are for Golden Gate Ferry, not every boat leaving the waterfront.

Three example family budgets

These examples use two adult Muni Day Passes and free Muni for the children. The food amounts are chosen spending allowances, not restaurant quotes. They exclude parking, travel into San Francisco, and any optional purchases.

Playground, carousel, and a picnic: $38.40

One carousel ride each ($7) + two adult Muni Day Passes ($11.40) + a $20 food allowance = $38.40. Use food already at home if that suits your budget, while remembering groceries have a cost too. Without the carousel, the same allowance comes to $31.40.

A swim and a snack: $41.40

Four recreation-swim admissions ($20) + two adult Muni Day Passes ($11.40) + a $10 snack allowance = $41.40. Confirm the session first so you do not pay to travel to a pool that is closed or reserved for another program.

An eligible museum day: $51.40

Four $5 daytime tickets through one of the museum programs above ($20) + two adult Muni Day Passes ($11.40) + a $20 food allowance = $51.40. This budget depends on qualifying for that museum's program and following its purchase rules.

Keep the plan affordable after you arrive

Choose one main paid activity, agree on extras such as rides or snacks before leaving, and leave room for free play. A playground afternoon does not need a museum added to it to count as a day out.

Before buying a membership, compare its total cost and the people it covers with the admission you would actually pay after discounts. Count visits you realistically expect to make. For garden free-entry windows, residency rules, and more no-admission-charge outings, continue with the free activities guide.

Two more ways to keep the activity budget small

The Embarcadero train outing combines the free Railway Museum with a public playground and an optional food stop. For a park-led day, consider Francisco Park and pack a picnic. Transport and food purchases remain separate costs.

For swimming, Balboa Pool now has a listing linking to its current family-swim schedule. Choose a recreation or family session rather than a lesson or lap-swim block.

Make a market the outing

Try the Clement Street Sunday plan, including books and an optional free park stop. Alemany Farmers Market runs on Saturdays; Heart of the City Farmers Market runs on Wednesdays and Sundays. Set a shopping budget before browsing; purchases are separate from the outing plan.
