We have been to Gettysburg a few times in the past, but never did a bus tour previously. We decided to try the Double-Decker Bus tour this trip, as we had previously done the self-guided auto tour on a previous visit (highly recommended for the first-time visitor.). We rode on the top deck, which is open-air, and had a great time. Plug-in ear buds are provided to listen to the narration as the bus takes a chronological tour of the battlefield sites and describes the events that occurred at each site. A very informative and enjoyable way to spend a couple of hours without walking or driving, and well worth the price. TIP: If you ride on top and wear a hat, make sure it is securely on your head!
