Insider secrets & local vibes
The hands-on exhibits, ecosystems hall and aquarium tank make it one of the best genuinely free family museums in the city.
Not independently verified — estimated
Space Shuttle Endeavour is not viewable right now — it has been off public display since the original pavilion closed at the end of 2023 and is being installed upright in the new Samuel Oschin Air and Space Center, which has no announced opening date as of mid-2026.
Not independently verified — estimated
It packs with school groups on weekday mornings, so it gets loud and busy during the academic year.

What it feels like
Reading the room, traveller by traveller
With kids
Still a free, hands-on hit on its own merits — just don't promise them the space shuttle, which is closed during the move.
Multigenerational
Accessible and free, easy to enjoy across ages for a couple of hours.
With friends
A cheap, fun couple of hours — but the headline shuttle isn't part of the visit until the new center opens.

Best time
Weekend or after-school hours have fewer field-trip groups; check Endeavour access first.

Metro E (Expo) Line to Expo Park/USC, in Exposition Park.
Booking
General admission is free; reserve a free timed ticket for the shuttle, and IMAX costs extra.
Space Shuttle Endeavour is now displayed vertically in the new Samuel Oschin Air and Space Center, whose construction completed April 13, 2026; an opening date is to be named in summer 2026, before the 2028 Olympics. californiasciencecenter.org ↗
