My son, nephew and I hiked from Ewing to the Sand Cave in the park once. It was quite a walk up the mountain but well worth it. I'm not sure how many miles of hiking trails there are inside the park but I know there was a "primitive" campground when you got to the top of the hill. To the right the trail led to White Rocks and the left was to Sand Cave and beyond. Once you are on the ridge it is easy walking, but the climb up wasn't.
