When rain hits Los Angeles, the best indoor options for families fall into four groups: science and discovery museums, hands-on kids’ museums, active indoor play like go-karts and trampolines, and cozy low-key spots like libraries and bowling alleys. Pick the group that matches your kids’ ages and energy, then choose a specific place from it.
Rain is rare here, which is exactly why it catches families off guard. Downtown Los Angeles averages only about 14 inches a year, and almost all of it falls between November and March, with February the wettest month, according to the National Weather Service. When one of those days lands on a weekend, this guide will save you the scramble.
Science and Discovery Museums
Large museums are the classic rainy-day move because they are big, warm, and can absorb a couple of hours easily. Two stand out for families.
The California Science Center in Exposition Park is the strongest value in the city, because general admission is free. It runs hands-on exhibits on biology, physics, and ecosystems, plus an IMAX theater that charges separately. Its Space Shuttle Endeavour is currently off display while the museum finishes the new Samuel Oschin Air and Space Center, which is scheduled to open on November 13, 2026 with the shuttle mounted upright in launch position. Even without the shuttle, the free galleries fill a rainy afternoon.
The Natural History Museum of Los Angeles County is the other reliable pick, with dinosaur halls, animal dioramas, and a hands-on Discovery Center where younger kids can handle real specimens. It leans educational and works across a wide age range.
Hands-on Kids’ Museums
For younger children, a dedicated kids’ museum beats a big institution, because everything is built at their scale and there is less to break or lose them in. These venues focus on play-based learning, so a rainy day turns into an afternoon of climbing, building, and pretend play rather than looking at exhibits behind glass.
- Kidspace Children’s Museum in Pasadena centers on hands-on exhibits and interactive play across a multi-acre campus, aimed at curious younger kids.
- Cayton Children’s Museum at Santa Monica Place offers a large indoor play-and-learn space designed for babies through early elementary ages, which is handy on the Westside.
Both keep the sensory load lower than a trampoline park, which suits toddlers and kids who get overwhelmed by big, loud rooms.
Active Indoor Play to Burn Energy
Some kids do not want a museum on a rainy day. They want to move. When the backyard and the park are out, indoor play centers, trampoline parks, and go-kart tracks let kids run down their energy without getting soaked.
This is where an all-in-one indoor center is useful, because it covers several ages at once. Kartopia in Van Nuys is a fully indoor, climate-controlled spot with go-kart racing, an arcade, and a soft play area under one roof. Older kids and adults can race the go-karts, which are open to anyone 36 inches or taller with no age limit. Children 8 and under play in the soft play area, and everyone shares the arcade. Because it is indoors, the weather outside makes no difference to the visit. Walk-ins are welcome Thursday through Sunday, though it is worth a call to 818-745-7575 first to confirm it is open to the public and not booked for a private event. You can check current walk-in pricing before you go.
Trampoline parks are the other high-energy option and suit kids who mainly want to jump, though many individual attractions carry their own age or height limits, so check those for very young guests.
Cozy, Low-Key Rainy Day Options
Not every rainy day needs a big outing. Some of the best ones are quiet and close to home.
- Library storytime: Most Los Angeles Public Library branches run free storytimes and kids’ programs. Check your nearest branch’s calendar.
- Bookstore afternoon: A children’s section and a warm drink can carry a slow, drizzly hour better than you would expect.
- Bowling or an arcade: An easy, all-ages way to spend a couple of hours out of the rain.
- A matinee: A mid-day movie is a low-effort classic when everyone needs to sit still and dry off.
These pair well with a bigger plan, too. A museum in the morning and a quiet afternoon at home is a full rainy day sorted.

Frequently Asked Questions
1. When is the rainy season in Los Angeles?
Los Angeles gets almost all of its rain between November and March, and February is the wettest month on average. The rest of the year is dry, and summers see almost no rain at all. Downtown’s normal seasonal rainfall is about 14 inches, per the National Weather Service.
2. What are some free indoor activities in LA for kids on a rainy day?
The California Science Center offers free general admission to its permanent galleries, which makes it a top free rainy-day option. Public library branches also run free storytimes and children’s programs. Both let you spend a wet afternoon indoors without a ticket cost.
3. What indoor activities are good for toddlers when it rains in LA?
For toddlers, a hands-on kids’ museum or a dedicated soft play area is safer and less overwhelming than a big attraction. Kidspace and Cayton children’s museums are built for young children, and indoor soft play areas, like Kartopia’s for kids 8 and under, give little ones a padded space to move.
4. Where can older kids and teens go indoors on a rainy day?
Older kids and teens usually want something active or competitive. Indoor go-kart tracks, arcades, trampoline parks, bowling alleys, and escape rooms all work well. Kartopia in Van Nuys combines go-karts and an arcade indoors, so a rainy day still delivers speed and competition.
5. What are rainy day activities in the San Fernando Valley?
The Valley has solid indoor options without a drive over the hill. Kartopia in Van Nuys offers indoor go-karts, an arcade, and soft play in one climate-controlled building, and the wider Valley has trampoline parks, bowling alleys, and library branches with kids’ programming. All keep a wet day moving.
6. Do I need to book indoor activities in advance on a rainy day?
It depends on the venue. Some museums use timed-entry reservations, and busy play centers can fill up on wet weekends. Walk-in spots like Kartopia welcome drop-ins Thursday through Sunday, but a quick call ahead confirms availability and saves a wasted trip in the rain.
