Book a Tour at The World’s Largest Marine Mammal Hospital
The Marine Mammal Center is nestled in the Marin Headlands in the beautiful Golden Gate National Recreation Area, just minutes north of the Golden Gate Bridge. We offer educational programs and tours; plus, you are welcome to explore on your own – view exhibits and our animal patients. Admission is FREE but tours are highly recommended (the small fee helps save our seals and sea lions!)

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).
