Friday I started fairly early on the "motor nature trail", a single lane, paved, twisty, beautiful road which climbed fairly quickly along a river, to a trailhead for the Grotto waterfalls. I was early enough to find parking easily, and the trail was minimally occupied. The hike was 1.4 miles along a fairly soft forest path, with frequent tree roots threatening to grab one's foot, twist an ankle, etc. I managed to get there without any mishap. The falls comes over a cliff with a recess (cave) behind the falls to allow hikers to go behind the water and continue to the other side, and on up a trail. I spent about an hour just looking, taking photos, and watching as the later hikers began to fill up the area. When it became obvious that there was not enough room for everybody, I hiked back down and continued on around the "motor nature trail" for a total of 11 miles. Along the way there were several old settlements, farms with outbuildings, in the middle of the woods.
