The very beginning of this trail is steep. I would rate it as moderate until the actual loop starts. Then the inclines are more gradual and much less strenuous. The entire trail is wide and a mix of small stones and sand areas. The views are outstanding. The only complaint is the clutter that the forestry service has put out. there are several areas with caution tape on the edge of the trail, about 500 do not enter signs spread out and some ugly yellow barricades near the triple falls area. It takes away from the natural beauty of the area. Ironically there is a small washed out area of the trail that has a natural wood fence around it that blends in much better. I wish the caution taped areas took the same approach. High Falls is absolutely a must see. There is a nice overlook that shows just about the entire falls and a bit of the covered bridge above the falls.
