The Getty Villa in Malibu is an educational center and museum dedicated to the study of the arts and cultures of ancient Greece, Rome, and Etruria.
The Norton Simon Museum is another really great museum to see in the Los Angles area in Pasadena. It's a great smaller art museum with the most significant collection of Impressionist and Post-Impressionist art in Southern California. Reflections of modern life captured by Claude Monet, Pierre-Auguste Renoir and Edgar Degas, who alone is represented by over one hundred works of art, are displayed alongside the vibrant palettes of Vincent van Gogh, Paul Cézanne and Paul Gauguin. Complementing these works are Auguste Rodin’s monumental bronze sculptures, which are displayed in the Museum’s front garden. Paintings by Jean-Auguste-Dominique Ingres and Francisco de Goya mark the beginning of the 19th century and lead to superb examples of mid-century Realism executed by Jean-Baptiste-Camille Corot, Gustave Courbet and Édouard Manet. Outstanding paintings by Édouard Vuillard and Pierre Bonnard carry us right to the doorstep of 20th-century Modernism. A must see!
Also neat: Los Angeles County Art Museum and Page Museum - La Brea Tar Pits.
