Time of year
Unfortunately the stairs were closed during this visit. It appears a few areas are under renovations, and repair. Some areas completed, and very nicely done. Make the trip along the rim if you are able.
No indication other than at the trail head that it was closed. later in the week there was a small paper sign outside the Canyon Visitor Center.
We end up waking the canyon - which is pretty boring I must say -Not strenuous enough and full of people ...
Closed. Not for the faint of heart when it reopens. Saw it from the north rim trail. It's being rebuilt as we understood.
It's a quick hike down to view the falls. It's a lot of steps but it's not difficult, just take your time.
