Civil War Traveler offers audio tours given by National Park Service historians. These tours can be accessed directly through the site or via a free subscription in iTunes. Each podcast episode follows a historian as he walks along a famous Civil War battlefield or location such as Antietam or the Appomattox Court House. Since they record each episode live at the battlefield as the historian walks the site, you can download these audio files to a portable music device and use them as your own personal guide at each historic site. The website also has downloadable maps of each historic location in pdf form to help you stay in sync with your guide. This site would be great for bolstering field trips or for teachers who enjoy using their imagination. Students can listen to the tour and follow the guide’s route on the map for a rather engaging experience.
