What animals will you see?

  • February to May: Pupping season! You’ll see northern elephant seals and California sea lions. Harbor seal pups are not on view, except during behind-the-scenes tours, because they are very fragile and sensitive to human disturbances.
  • June to October: Sea lion season with some of the last northern elephant seals and harbor seal pups from the spring getting ready to return to the wild.
  • November to January: It's our quieter season on the animal front, but the weather is glorious, so join us for a tour and get some early holiday shopping in our great eco-minded gift store (all proceeds benefit the patients).
  • Check out our Patients page to see which animals are at our hospital right now!
  • Sign up for email to receive patient stories and information about upcoming events and opportunities to help save marine mammals.
