GETTYSBURG, Pa. » A twig snaps and brush rustles in woods on the Gettysburg battlefield. My horse does not flinch. It’s nothing more than a small animal scurrying away. But on a hot summer day nearly 150 years earlier, it could have been the enemy.

The rolling farmland that is Gettysburg can be toured in a number of ways, but on horseback you can transport yourself to the vantage and vulnerability of a Civil War officer directing his troops in the three-day battle. On a recent family trip, my husband, our daughters, ages 9 and 14, and I toured the battlefields on horseback with a licensed battlefield guide. The tour allowed us to go into sections of the battlefield that were not part of auto or bus tours and provided intricate details of the July 1-3, 1863, battle that was a turning point in the Civil War.

Horse tours have been offered for decades by farms in the area. But with the 150th anniversary of the Civil War under way and the 150th anniversary of the Gettysburg battle approaching in the summer of 2013, this is an ideal time to visit.

Pamela Grimes, owner of Hickory Hollow Farm, has up to 15 horses available for battlefield tours, and says visitors need not have any experience riding. The horses fall into step while walking along the wooded dirt trails, kicking up clouds of dust along the way, and need just a little direction from riders to keep them in line, but all four of us novices were fine. Grimes, with a helper and a licensed battlefield guide, Les Fowler, also accompanied our tour.

As we mounted our horses with the help of a stepstool, Grimes’ team told us our horses’ names and a little about their personalities. My 9-year-old daughter Madigan’s horse, Spirit, was quick and likely would have been used as a messenger or scout horse in 1863. My husband Rob’s horse, Pebbles, was a calm leader and took the front of the line. My horse, Raggity Ann, liked to snack on brush or grass along the trails. Our daughter Nicole’s horse, Rock, was a bit slower and brought up the rear.

Much of the battlefield now appears as it did in 1863, when Confederate troops moved into Pennsylvania that hot summer, so it is easy to grasp the vulnerability of troops marching across an open field or having the advantage of being on the high ground. The battlefield has undergone a landscape rehabilitation since 2000, including cutting nonhistoric trees, replanting orchards and rebuilding missing fences, to make it appear much as it did 150 years ago, said spokeswoman Katie Lawhon at Gettysburg National Military Park, which averages about 1.2 million visitors a year.

"Now, you can get a wonderful feel for what the soldiers actually saw. This field has changed dramatically in just the seven years that I have lived here," said Fowler, the battlefield guide.

Most of the buildings on the battlefield in 1863 are still standing and are well-maintained. In addition, there are more than 1,300 monuments and 400 cannons. Rocks and other markers seen in iconic Civil War photographs make it easy to pinpoint exactly where the picture was taken.

Our ride lasted 21⁄2 hours and covered about four miles round-trip.The tour was point-to-point, with riders gathering around Fowler at key spots between riding to hear the story of what we were seeing.

Our group then headed to the site of Pickett’s Charge, where thousands of troops of the Army of Northern Virginia marched toward Union lines on July 3, their own line nearly a mile wide. The famous, futile charge was named for one of the Confederate generals, Maj. Gen. George Pickett. After being slowed by climbing fences along the nearby road, they came into range of the Union infantry on Cemetery Ridge, which we could see less than a mile away.

Fowler described how the Confederate line shrunk to nearly half its size as it closed in to cover the gaps left by wounded and killed men. It was easy to imagine as we could see the tree lines, fences and fields in front of us.

Gettysburg is commemorating the 150th anniversary of the Civil War through 2015. Interest is expected to increase as the actual date of the 150th anniversary of the battle approaches in summer 2013. Living history encampments and other events are planned.

As attendance and interest in the site grows, tours are increasingly in demand, so reservations are a must — whether you’re looking for a horseback tour or a tour by one of Gettysburg’s 160 licensed battlefield guides.

"For many people, Gettysburg is such a significant event in our nation’s history, and it actually in some ways defines who we are as Americans today because of the tremendous crisis of that battle," she said. "It can be a tremendously moving place."
