Top 10 ghost-heavy spots: Gettysburg 150

We asked Gettysburg Ghost Tours, After Dark Investigations, Haunted Gettysburg Ghost Tours, Ghostly Images of Gettysburg and Mark Nesbitt's Ghosts of Gettysburg Candlelight Walking Tours for the spots in Gettysburg with the most paranormal activity. Here's what they said - but do keep in mind that many of these locations can only be visited while on a tour.

1. Sachs Covered Bridge (Water Works Road) is one of the most haunted spots in Gettysburg according to all of our sources. This area, however, is not accessible after dark unless on a tour. Soldiers have been spotted there and there are numerous photos of mists and orbs taken there.

2. The Grove, located behind Warrior Stadium and the Gettysburg Area Middle School (37 Lefever St.), was mentioned by both After Dark Investigations and Haunted Gettysburg. It's a favorite for ghost tours, which are not allowed on the battlefield.

3. Devil's Den on the battlefield is incredibly haunted, with one particular Texan soldier ghost being seen as recently as 2010 according to Mark Nesbitt of Mark Nesbitt's Ghost of Gettysburg Candelight Walking Tours.

4. Servant's Olde Thyme Photos (237 Steinwehr Ave.) is the current business residing in what is known as the Reynolds Death house. It is in this building that General Reynolds, the first Union General killed in the Battle of Gettysburg, died.

5. Tillie Pierce House Inn (301 Baltimore St.) is said to be haunted by a ghost cat as well as multiple children - all friendly ghosts - according to Gettysburg Ghost Tours.

6. Hoffman Mansion is only available to be toured by those on a Gettysburg Ghost Tours paranormal investigation ($30-$33 per person). "It's a large mansion, abandoned for decades and it has more spirits than it has rooms," says Gettysburg Ghost Tours owner Johlene "Spooky" Riley.

7. Jennie Wade House (548 Baltimore St.) has been featured on "Ghost Lab" and "Ghost Adventures" and is available for ghost tours only from Ghostly Images. The Jenny Wade House is the home of the only civilian death of the Battle of Gettysburg.

8. Children's Orphanage (777 Baltimore St.) is more than just the headquarters for Ghostly Images, it's a haunted building in its own right. The orphanage began in the 1860s, but was shut down more than 20 years later after it was discovered that the owner was keeping the orphans chained to walls in the cellar.

9. The area around Doubleday Inn (104 Doubleday Ave.) is rife with paranormal activity according to Nesbitt. By the Doubleday Inn is an area known as Iverson's Pit, where a brigade of North Carolinians were slaughtered. The pit is the location of the mass grave for the soldiers and is a spot where ghosts are seen today.

10. Gettysburg College (300 N. Washington St.) is loaded with ghost stories, according to Nesbitt. Many of the stories of his book series, "Ghosts of Gettysburg," take place at the school - from soldier sightings to people stepping back in time (you'll have to read his books to get the full details).
