Marine Mammal Care Center at Fort MacArthur, Los Angeles

This complex is a fine alternative to ocean-themed parks like San Diego's Sea World. Here, you can view sick or injured seals and sea lions rehabilitating in preparation for their return to the ocean. The center, run by two full-time staff members and a number of volunteers, caters primarily to California Sea Lions, Northern Elephant Seals, Northern Fur Seals and Harbor Seals. The center also has a gift shop and exhibits with materials intended to educate the public about marine mammals. Admission is free.
