"Stargazing at Los Angeles's Window to the Cosmos Sitting nearMount Hollywood in Griffith Park, the Griffith Observatory has a vantage point that allows visitors great views of the HOLLYWOOD sign during the day, and even morefantastic views of the stars at night. The space has plenty of telescopes for stargazing, but it's also a great informal setting for learning about the universe, thanks to a large exhibit space and a 290-seat planetarium that puts on rotating shows about topics ranging from the northern lights to water—and possibly alien life—on other planets. There is no entrance fee for the institution and just a small admission price for the planetarium itself."
