California Science Center
The California Science Center in Exposition Park, Los Angeles, is one of the city's standout attractions: a massive, free-admission science museum that pairs an authentic space shuttle legacy with living ocean ecosystems and hands-on sports science—all open daily without a ticket reservation for its core galleries. Right now the Center is in a moment of major transition. Space Shuttle Endeavour—fresh from 25 missions and 122 million miles in space—is being prepared for its grand reveal in the brand-new Samuel Oschin Air and Space Center, opening November 13, 2026. Until then, visitors can still explore the Kelp Forest, Ecosystems gallery, the wildly popular GAME ON! sports exhibit, and an IMAX theater, with rotating special exhibitions like Mummies of the World adding ticketed highlights.
