This is going to sound odd to not recommend a beautiful hike as someone who loves the outdoors but with so many options of how to occupy what for most is limited time in the area I just cannot recommend this to be near the top of the list for many and is downright a bad choice for others.
Contrary to what you may have read are Zero scary sections, even if you had a fear of heights you are never hiking close to a drop off on the entire trail.
I am basing this on my experience of starting in Bommerano and done as a one way with the ending point of Positano (normal recommended route)
reason 1: It is a well defined trail but many rock sections which require some knowledge or at least need to be very mindful of proper foot placement. Good traction most definitely needed, the fear of a dangerous fall is not present but a twisted ankle or similar definitely is. A good level of fitness and water is also needed. Compared to most US National Park hikes or other European mountain hikes I have done this path is more natural ; less graded than I expected. The part close to Nocelle especially.
reason 2: Where the path starts is hard to get to and that combined with a long hike truly takes a full day. If this could be done in only part of a day I would feel quite differently but taking up an entire day and exhausting one self could also affect the following day so you really need to think this through. Getting to Bommerano takes a long time, no tourist is going there except for taking this hike, the car route can involve a ZTL from the coast. From where the bus/parking is in Bommerano it takes a little walk to get your first views and the approach to Nocelle is filled with rock sections that take time and effort.
reason 3: It has become so popular with tourists and locals alike that you likely won't get the alone in nature experience that you want. Many groups come through that are quite loud, reduce any chance of seeing wildlife and with the starting point of Bommerano being hard to reach too early in the AM it would be difficult to hike without the masses. We went in May, in June, July, August, Sept it likely would be far worse.
reason 4: I am not sure any of the viewpoints are better than areas you could reach without a hike. In addition there are sections you really don't have views. The view of the Coast and to Capri about 1/3 of the way you can see the same or better from a higher angle if driving from another part of Bommerno. Does not look easy/short to drive there but can be done if you want to see that view. The other great view is overlooking Positano from above but can get that from Nocele or on the stairs which you don't need the actual path for.
There are some nice terraced hillside views and some ruins over the sea you overlook on the hike which you might not be able to see otherwise.
it is beautiful: yes
am I happy we did it: I think I made a mistake choosing it over other things we could have used the day for.
It was our second time in the Amalfi Coast and have heard so many great things about this hike, I decided we must include ti this time around.
Which is the reason for the non-recommendation overall, there is just so much to see and do and so little time for most travelers that I am not sure why this hike gets only glowing reviews when there are some definite negatives.
If hiking is a major reason for your visit to the Amalfi Coast than don't let this review change your opinion, I would instead recommend you make it a round trip from Bommerano ; looking on a map the path splits, take the higher route one way and then when the two paths join take the other back toward Bommerano. The remaining section once the paths merge and continue it's rocky mostly un scenic way onto Nocelle as well as the endless stairs and walk onward to Positano can be avoided this way which makes it a better overall hike provided you are up for what would then be about 7 miles of R/T.
