Many trails to choose from in the park ranging from forested lake trails to the most popular mountain trail that takes you to the summit of Stone Mountain. The mountain trail traverses the exposed granite monolith starting in a thin pine forest and eventually gives way to a completely exposed and sometimes steep ascent. Bring plenty of water on hot days!
From Atlanta, take US 78 East approximately 5 miles past I-285. Look for exit signs directing you into the park. $8 per car entry fee as of 9/17/08.
