Griffith Observatory
Probably the best view of Los Angeles and one of my favorite tourist traps. You can get a hike in, check out the Hollywood sign, and maybe even see a film crew at work. Since I was a kid, I have always been drawn to the observatory. There is something special about looking through that big fancy (Zeiss), telescope, and getting zoom in on stars and planets. It is at the Griffith Observatory that I saw that Uranus has rings!!
