What Travellers Say
Reviews Summary
Visitors consistently praise The Marine Mammal Center for its incredible work in rescuing and rehabilitating marine mammals. The dedication of the staff and volunteers, combined with the educational aspect of the visit, leaves a lasting positive impression. Some visitors note that it's a working hospital, not a petting zoo, which is important to understand.
"A fascinating, working hospital engaged in the rehabilitation, research, and release of wild marine mammals of the California Coast and Hawaii. While you can visit spontaneously, booking a tour in advance is highly recommended. You'll learn about the history of the organization, the active medical workings of the facility, and even the names of the animals in their care. They help hundreds of seals, sea lions, and otters each year. Your admission and contributions help make it possible. Highly recommended."

"One of the gems to visit in the Marin Headlands, part of NPS' Golden Gate National Recreation Area is the Marin Mammal Center.
The Marine Mammal Center is a remarkable organization with three key distinguishing features:
• Extensive Marine Mammal Rescue Efforts: Since its founding in 1975, the center has rescued over 24,000 marine mammals across a 600-mile coastal range including California and Hawaii.
• Comprehensive Research and Conservation: The center goes beyond simple animal rescue, conducting critical scientific research that provides insights into marine mammal and ocean health.
• Innovative and Sustainable Facility: Located on a former Nike Missile site in the Marin Headlands, the center features a state-of-the-art facility built with sustainability in mind.
Remarkably, they can care for up to 275 animals simultaneously and have specialized facilities including a veterinary hospital with capabilities for complex surgeries."
