I started off on the South Ridge Trail which has some decent elevation gain but not too terrible, went to the AT, down Ambassador Whitehouse and detoured off to the North Ridge Trail instead of the Piedmont Overlook so that I could stay in the shade (the trail to Piedmont Overlook is mostly in direct sunlight) - was roughly 5.5 miles. It was very buggy - be sure to bring bug spray. Some sections of the South and North Ridge Trails were a bit overgrown - so long pants may be best. Beautiful views and some amazing wild flowers! There is a $5 admission fee. You can pick up a park map at the entrance. There is plenty of parking at the visitor center (with an overflow parking lot for busy days). There are also bathrooms at the visitor center.
