Some amazing historical, scholarly, or cultural celebs buried there, and some very lovely grounds and monuments. Get the guide and map at the visitors' center near the entrance. You can drive in and park, but note carefully where you can and cannot leave the car. Two warnings: it's very hilly, with many of the celeb markers hard to find; and the map you get is unwieldy and doesn't always seem to match up with where you are. It's on the 71 or 73 bus lines from Harvard sq. if you don't want to drive.
