The California Science Center is a free museum in Los Angeles focused on science, technology, and natural history

The California Science Center sits in Exposition Park in Los Angeles and does not charge admission. The museum holds permanent exhibits on space exploration, life sciences, and physical sciences, plus rotating temporary exhibits that change throughout the year. You can spend anywhere from two hours to a full day there depending on how deeply you explore.

The building itself is large — roughly 400,000 square feet across multiple floors. Most exhibits are hands-on, meaning you can touch, manipulate, and interact with displays rather than just read plaques behind glass. The museum is run by the state and is open most days of the week, though hours and closures vary by season.

Key Takeaways

  • Admission is free, but parking in Exposition Park costs money unless you have a permit or use street parking.
  • The museum is closed on certain holidays and occasionally for maintenance, so check the website for hours before you go.
  • Popular exhibits can have long waits during peak times like weekends and school holidays, especially for the IMAX theater.
  • You can bring your own food and eat in designated areas, or buy food at the on-site cafeteria.
  • Strollers, wheelchairs, and mobility devices are allowed throughout the museum.

What exhibits and attractions are inside

The permanent collection includes the Space Shuttle Endeavour, which is the centerpiece of the Aerospace exhibit. You can walk around and under the actual shuttle to see its size and detail. Other major permanent sections cover human biology, ecosystems, physics, and technology.

The museum also runs an IMAX theater that shows large-format films, usually with a science or nature focus. IMAX tickets cost extra and must be purchased separately from general admission. The films change periodically, so what is showing depends on when you visit.

Temporary exhibits rotate and focus on topics like engineering, environmental science, or specific historical events. These change several times per year, so the museum offers something different if you return.

Hours, parking, and how to get there

The California Science Center is located at 700 Exposition Boulevard in Los Angeles, inside Exposition Park. It is open most days from 10 a.m. to 5 p.m., though hours may be shorter on certain days or seasons. The museum is closed on Thanksgiving, Christmas, and New Year's Day, and occasionally closes for maintenance or special events.

Parking in Exposition Park costs money — rates vary but typically run several dollars per hour. Street parking is available in the surrounding neighborhoods but can be difficult to find during busy times. Public transit options include the Metro E Line (formerly the Expo Line), which stops near the park entrance.

Before you go, check the official website for current hours, any temporary closures, and parking information, as these change seasonally.

What to bring and what to expect on a busy day

Wear comfortable shoes — you will be walking and standing for hours. Bring water and snacks, or plan to buy food at the museum's cafeteria. The building has restrooms on multiple floors. If you are visiting with young children, note that stroller parking is available but can fill up during peak times.

Weekends, school holidays, and summer vacation are the busiest times. If you prefer a quieter experience, visit on a weekday during the school year. Popular exhibits like the Space Shuttle area and IMAX theater develop lines during peak hours, sometimes an hour or more. Arriving early in the day usually means shorter waits.

The museum is air-conditioned and climate-controlled, so it is a good option on hot days. Crowds tend to thin out in the late afternoon, so if you arrive closer to closing time, you may have more space to move around.

Tickets for the IMAX theater and special programs

General admission to the museum is free, but the IMAX theater requires a separate ticket. IMAX ticket prices vary depending on the film and your age — children, seniors, and students typically pay less than adults. You can purchase IMAX tickets at the museum or sometimes online in advance.

The museum occasionally offers special programs, workshops, and evening events that may have their own fees. These are listed on the museum's website and change throughout the year. School groups can arrange guided tours, though these must be booked in advance.

Accessibility and facilities

The California Science Center is wheelchair accessible throughout most of the building. Elevators, accessible restrooms, and accessible parking spaces are available. Service animals are allowed. If you need mobility information or have questions about specific accessibility needs, contact the museum directly before your visit.

The museum has a family restroom, nursing areas, and water fountains throughout. Lockers are not available, but you can store bags at coat check during your visit. The building has benches and seating areas where you can rest if you need a break.

Planning your visit and what changes seasonally

The museum's website lists current exhibits, hours, and any temporary closures. You can also call ahead if you have specific questions about what will be open on the day you plan to visit. During the summer and major holidays, the museum is typically more crowded and may have extended hours.

If you are interested in a particular exhibit or the IMAX film, check what is currently showing before you go, as both rotate. Some exhibits are permanent and always available, while others are temporary and may not be there if you wait too long.
