If you didn’t get a chance to add some paint to a fence post or clean up trash or just plain make a visit to a battlefield or historic building on Park Day in March, another opportunity comes up in June.

Sponsored by the American Hiking Association, the annual National Trails Day is a celebration of the country’s 200,000 miles of urban and rural trails and is meant to get the public outside to enjoy them.

Some Civil War sites have joined in the effort. Although the official day is June 2, some of the events are taking place on the next weekend.

At the Appomattox Court House National Historic Site in Virginia, volunteers are invited to scrape and paint a large section of fence that begins at the courthouse and ends at the parking lot, from 8:45 a.m. to 3:30 p.m. on June 2.

In Georgia, the Kennesaw Mountain Club needs help on June 9 beginning at 8:30 a.m. to maintain trails that lead to Civil War battlefields and are bordered by historic entrenchments. The work includes picking up litter on the trails and adjacent roads.

In Tennessee, Fort Pillow State Park is offering a five mile hike at 9 a.m. on June 2 that ends at the well-preserved Confederate-built earth works and restored fortification made famous on April 12, 1864 by Maj. Gen. Nathan Bedford Forrest. On that date, his troops are accused by some historians of intentionally killing the defending black soldiers after they had surrendered. The battle is still referred to as the Fort Pillow Massacre.
