I hiked this trail in May of 2017 with my 7 year old son and family. The terrain is super flat and really could be done in running shoes with grip on the sole. It is not difficult on the legs or anything (for an active person), but can difficult for someone who is not active but still doable!

We actually hiked the entire trail down to the beach, hung a left and kept walking down the beach to the falls. After, we climbed the rocks to the top and took the short cut back. This is not full 8 miles if you take the short cut, tbh. It can be slippery over the smaller water falls but doable.

The falls are spectacular and sitting at the edge overlooking the water is so peaceful. It is super trafficked, however, that was the only downside.
