Kids are expensive. Theme park tickets for a family of four can cost more than the flight. The good news is that there are plenty of free things to do in San Diego with kids, and most of them involve sand, sea creatures or a playground, which is all most kids want anyway.
The catch is the fine print: free for kids but not adults, free for residents but not visitors, free to enter but not to park. We flag every one. Traveling without kids? Our free things to do in San Diego post has the grown-up picks.
TL;DR (for parents with 4 minutes before a meltdown)
- Best overall: the Cabrillo tide pools at a low tide. Kids 15 and under get in free, and it’s a real-life aquarium.
- Best for toddlers: Mission Bay’s calm beaches. No surf, free parking and room to dig.
- The skip: planning a visit around Residents Free Tuesdays when you don’t live here. It’s for San Diego City and County residents only.

1. The Lily Pond and Botanical Building
The Lily Pond in Balboa Park is long, flat and full of lily pads. Kids will want to go in. They can’t. The Botanical Building behind it is free and open 10 a.m. to 4 p.m.
Parking: the park is free, but its lots cost money for visitors until paid parking ends Jan. 1, 2027. Lower Inspiration Point gives visitors 3 free hours, and a free tram runs from there 8 a.m. to 8 p.m. Our Balboa Park parking guide has every lot.
2. Museums that are always free for kids
A few Balboa Park museums let kids in free any day. The San Diego Museum of Art gives free general admission to youth 17 and under. So does the Mingei International Museum, which is free for everyone on the third Tuesday of the month. The Timken Museum of Art is always free for all.
Tip: At the Museum of Art, kids 14 and under must stay with a parent or guardian at all times. Special exhibits can cost extra, so check before you go.
3. Residents Free Tuesdays (not for visitors)
Let’s be plain about this one. Balboa Park’s Residents Free Tuesdays are for residents of the City and County of San Diego, plus active-duty military and their dependents. You’ll need a photo ID with your address. Visitors pay regular admission.
If you do qualify, the first Tuesday covers the Fleet Science Center and the Natural History Museum. The second covers the Air & Space Museum, The Veterans Museum and the Comic-Con Museum. Some museums only include permanent collections. Our Balboa Park parking guide covers the full schedule.
4. Pepper Grove and Sixth Avenue playgrounds
Balboa Park has two big playgrounds, both free. Pepper Grove, on Park Boulevard south of the Fleet Science Center, is split by age. The under-5 side has a giant sandbox, cushioned floors, slides and swings, and there are restrooms and picnic tables. The City lists it as open 6 a.m. to 10 p.m.
The Sixth Avenue Playground, at Sixth and Spruce, has a fire engine-themed climber for little kids. Pair it with the Spruce Street Suspension Bridge, which bounces enough to thrill a 6-year-old.
Parking: the Pepper Grove lot costs nonresidents $10 a day. Sixth Avenue meters are $2.50 an hour, with a 4-hour max.
5. Cabrillo tide pools: free for kids, not adults
This is the one kids talk about at dinner. The Cabrillo tide pools at the tip of Point Loma are full of anemones, crabs and sea hares. Kids 15 and under get in free. Adults pay: $20 per car, or $10 per person walking or biking in.
The park also has fee-free days. The two left in 2026 are Oct. 27 and Nov. 11.
Timing: the National Park Service says to aim for a tide of 0.7 feet or lower. Fall and winter bring the best low tides during park hours. The tide pools open at 9 a.m. and close at 4:30 p.m.
Safety: wear shoes with grippy soles, not flip-flops. The rocks are slippery with water and algae, and the dirt path down is steep. Keep small children close. Watch the waves, and never turn your back on the ocean. There’s no cell service down there.
Rules: touch animals only very gently, don’t lift or turn rocks, and don’t take anything, not even a shell. Leave the buckets and nets at home. Pets aren’t allowed in the tide pools.
6. The Children’s Pool seals
The Children’s Pool in La Jolla has a seawall that was built to make a calm swimming spot for kids. The harbor seals took it over, and now it’s a free place to watch them nap. The seawall walk gives you a good view.
Wildlife warning: the beach closes to people from Dec. 15 to May 15 for pupping season. When it’s open, stay behind the rope and far back. NOAA Fisheries recommends staying at least 100 yards from seals on the West Coast. Seals can bite, and harassing them is against the law. No dogs are allowed on this beach.
Water warning: the City warns that the reefs here can create strong currents, especially in high surf.
7. Old Town San Diego State Historic Park
Old Town is history kids can walk through: adobes, a stable and an old newspaper office. California State Parks lists free tours and activities for kids. The museums are open 10 a.m. to 5 p.m., though hours depend on staffing, so call ahead.
Parking: free lots, with a 4-hour limit. More in our Old Town guide.
8. Library storytimes
The San Diego Public Library runs free storytimes, music and craft programs for kids. The Denny Sanford Children’s Library, on the first floor of the Central Library, has a baby and toddler play area, kid-sized restrooms and a nursing room. Check the library’s event calendar for times.
San Diego with toddlers: calm water, flat paths
Toddlers don’t need a big itinerary. They need water without waves, a sandbox and a nap. These picks deliver.
9. Mission Bay’s calm beaches
Mission Bay has no surf and no significant currents, and parking is free. There are 8 official swimming areas. Bonita Cove, Leisure Lagoon and De Anza Cove get the most regular lifeguard coverage. Tecolote Shores has a playground designed for kids with disabilities and wide paved walkways for strollers.
Safety: lifeguards are seasonal, with none on duty from November to spring break. Stay within arm’s reach of toddlers in the water. The County also advises staying out of ocean and bay water for 72 hours after rain. Check sdbeachinfo.com before you go.
10. Coronado Ferry Landing
Coronado Landing Park has a small sand beach on the bay, skyline views and bike paths. The Port lists it as open 6 a.m. to 10:30 p.m., with free and paid parking. The ferry ride over costs money, but staring at boats from the sand doesn’t. See our Coronado Ferry page.
11. Kate Sessions Park
Kate Sessions Park is a big, free hillside lawn above Pacific Beach with views over Mission Bay. Its children’s playground is at the north entrance off Soledad Road. Bring a kite. Park entry is free; check parking before you go.
Bonus: the zoo is almost free for kids
The San Diego Zoo isn’t free for grown-ups. But kids under 3 always get in free. Every October, kids 11 and under get in free too, with up to 6 kids per ticketed adult. In 2026 that runs Oct. 1 to 31. Our San Diego Zoo survival guide covers the rest.
