Did the 7.5mile loop starting from the educational center going clockwise. Quite a few up and downs which made this trail a good workout but nothing I would consider in the difficult level. Nothing much to see other than a viewpoint and the waterfalls which are located on a short spur. The view is nothing spectacular but the waterfalls were very nice, especially with all the rain we've been getting. I imagine the falls get pretty busy given the shorter 3.5mi loop available. I did this hike during a rain storm and had the trails and falls mostly to myself on a mid morning Saturday.
