Los Angeles, California: Mount Wilson Observatory

Historic telescopes are the main attraction -- the 60-incher (1908) is the largest in the world open exclusively to the public for astronomical viewing. The non-telescope views of the LA basin from 5,715 feet above sea level are nice, too, on clear days.

Mount Wilson Observatory

Mount Wilson's 100-Inch telescope was the world's largest from 1917 to 1948. In 1923 Edwin Hubble proved that there are other galaxies beyond Milky Way, and in 1929 Hubble discovered that the universe is expanding. The grounds of the Mount Wilson Observatory are open every day from 10 to 5, including the Viewing Gallery inside the 100-Inch Telescope dome. It's a half-mile walk from the parking lot, at an elevation of 5,700 feet, with spectacular views. There's also a museum along the paved path. All are free. Guided tours are available for a fee, and occasional public viewing events allow visitors to look through the historic 100-Inch telescope, known as The Most Important Scientific Instrument of the Twentieth Century.
