The falls are really something to take in on this one.
aside from the grand scale of the falls and the beautiful landscape the one big problem I had was, seriously slippery stairs, they helped a lot but, wow.
Another big one is the walk in from the roadway, seriously dangerous with how the traffic is.
My biggest issue was the trail marker chasing at the intersections. you could follow a blaze till a junction and it would say .9, after a time you hit another junction and the same destination is now 1.3 miles away, and no there was no other trail to take or missed markers.
very odd but none the less an amazing time.
