The Sea Lion Center at Pier 39 in San Francisco, California is unfortunately closed for renovations as of May 2024, expected to reopen sometime in mid 2204 [Tripadvisor].
However, you can still see the star attraction, the sea lions themselves! Hundreds of California sea lions have made Pier 39 their home since the 1990s, basking on the K-Dock [sftravel.com]. You can observe these barking, playful animals from the pier itself.
While the Sea Lion Center isn't currently open to offer educational exhibits and programs, there are other resources available to learn about these fascinating creatures. The Aquarium of the Bay, which operates the Sea Lion Center, has information about sea lions online [pier39.com]. The Marine Mammal Center, a nearby organization dedicated to marine mammal rehabilitation, also has educational resources and even a live webcam pointed at the sea lion colony!
