The 'Nat' houses 7.5 million specimens, including rocks, fossils and taxidermied animals, as well as an impressive dinosaur skeleton and a California fault-line exhibit, all in beautiful spaces. Kids love the movies about the natural world in the giant-screen cinema; the selections change frequently. Children’s programs are held most weekends. Special exhibits (some with an extra charge) span pirates to King Tut. The museum also arranges field trips and nature walks in Balboa Park and further afield.
