This one is on the west side of Kennesaw Mountain about a half hour outside Atlanta. Once you wade through all the traffic to get here, its a nice Hike. It's kinda challenging so most people don't want to mess with it. Because this is another Civil War site there is a lot of History here and some monuments you may want to check out. Once you reach the top of the Mountain, the view is Awesome. Back down the mountain can be tricky if you don't know what you are doing. Park Services keeps adding improvements to it, but that makes it less fun in my opinion.
It is a good hike that leaves you feeling like you actually did something. And because it's not just a stroll around the mountain, it's not too Crowded.
