I’ve been on this hike several times. Every time we go to the bottom of the upper falls. It can be a little sketchy when using the rope to get up the hill but besides that it is very do-able.
One thing I did that I noticed no one is talking about is the hike to the top of the upper falls.
Just to the right when facing the upper falls is a steep hill into the rocks that leads to a path at the top of the falls and a nice small pool to sit by with a spectacular view. This hike is very steep with loose dirt so I would recommend you know what you are doing. There is also a bit of climbing involved.
The view and the seclusion at the top is unbelievable though. If you are an experienced hiker i would highly recommend it.
