Here are general directions and some information, my friends.
Allatoona Pass Trail
2.5 miles, 2-3 hours; compacted soil and gravel; rated easy-moderate; maintained by Red Top Mountain State Park
The Allatoona Pass consists of the Western & Atlantic Railroad bed, two earth forts, trenches and outworks dug by Union troops during the Civil War, and the old Tennessee Wagon Road. The level railroad pass is 360 feet long and 180 feet deep through solid rock, and if you look closely you can see where dynamite blasted through the mountain. Interpretive signs guide your way as you journey back through the battlefield, much of which remains as it was during the Battle of Allatoona Pass on October 5,1864. Directions: I-75 Exit 283, east on Old Allatoona Road, cross railroad and continue one mile to parking area on left.
