30 Fun things to do with kids in California (2026 summer guide)

California summers can feel long in the best way. School’s out, the days stretch late, and nearly every region, from foggy redwood coast to desert night skies, has something that makes kids light up. The challenge for parents and guardians is not finding something to do, it’s choosing ideas that fit your child’s age, your budget, and the temperature where you are.

This 2026 summer guide pulls together 30 kid-approved outings across the state, including theme parks, beaches, museums, trains, science centres, and big-nature day trips. I focused on places with strong family facilities, shade and indoor backups, and clear logistics like parking and snack options. Wherever possible, I’ve included a practical detail you can plan around, address, typical hours, and ticket pricing ranges that families commonly see in summer.

Before you lock anything in, double-check operating hours and reservation requirements, especially for state parks and national parks, which can change with fire conditions and peak-season crowd control. For the most current park alerts and closures, the National Park Service is the best place to start: https://www.nps.gov/.

Looking for an easy add-on if you already have beach plans in L.A.? Keep an eye on waterfront programming and pop-ups, Port of Los Angeles announces summer event lineup is a good starting point for what’s happening around the harbour.

Best theme parks for kids in California in summer

Theme parks are the classic California summer move, and they’re also where planning pays off the most. If you can swing a weekday, arrive at rope drop, and pace your day with air-conditioned breaks, you’ll get far more value and fewer meltdowns.

• Disneyland Park and Disney California Adventure, 1313 Disneyland Dr, Anaheim, CA 92802. Typical summer hours vary by day, often 8 am to midnight. Tickets are date-based and commonly start around the mid-$100s per person per day, higher on peak dates. Official site: https://disneyland.disney.go.com/.

• Universal Studios Hollywood, 100 Universal City Plaza, Universal City, CA 91608. Typical hours often 9 am to 9 pm in summer, check daily calendars.

If your summer calendar leans heavy on events rather than rides, also scan the school-year wrap-ups and student showcases, they often spill into early summer and include family-friendly programming. This can point you to district-wide celebrations, much like Ontario’s best summer activities for kids. One example to watch is coverage like Los Angeles Unified celebrates student success as school yea, which can point you to district-wide celebrations.

Best zoos and aquariums in California for families

When it’s hot inland, zoos and aquariums can be a smart choice because they typically offer early hours, shaded paths, and indoor exhibits. Bring refillable water bottles, and budget for a snack splurge if your kids love souvenir cups.

Best beaches, tide pools and coastal stops for kids

If your family is building confidence on trails, pair a coastal day with an easy hike. Our statewide round-up California's best hiking trails: 15 must-see hikes for all s is a good starting point for kid-friendly distances and seasonal notes.

Best national parks and big-nature day trips with kids

Big nature can be the most memorable part of a California summer, but it’s also where heat, altitude, and crowds hit hardest. In peak weeks, plan earlier starts, shorter hikes, and clear “win conditions” like a waterfall, a lake, or a junior ranger badge.

• Yosemite National Park, Yosemite Valley entrances and visitor areas. Hours: 24 hours, but facilities have set hours. Cost: entrance fees apply, plus possible reservations in peak periods.

Because wildfire season is now a standard part of summer planning, it’s worth following local updates. When incidents do happen, like Lost Fire burns 520 acres in Kern County, it can affect air quality and access even far away. Always check conditions before you leave.

Best kid-friendly museums and science centres (great for hot days)

For families who need air conditioning, museums are the summer secret weapon. Many also have membership reciprocity, which can pay for itself in two visits if you live nearby.

If you want to tie museum days to real-world inspiration, it can be fun to connect STEM outings to local health and science stories. For example, Touro University sends 400 new graduates into health care is a reminder that today’s museum kid might be tomorrow’s nurse, doctor, or lab tech.

Best free or low-cost things to do with kids in California

Not every summer outing needs a ticket. A few “free anchors” each week can make the paid days feel special, and keep the budget intact.

• Golden Gate Park playground loop, San Francisco, CA 94122 (multiple playgrounds, including Koret Children’s Quarter area). Cost: free. Hours: daylight. Tip: bring a picnic, and make it a hop-on-hop-off day with playground breaks.

If animals are what your kids are begging for, keep an eye on local adoption events too. Even if you’re not ready to adopt, these days can be a gentle, educational outing. See: Canoga Park joins statewide fee-waived pet adoption day.
