I am such a nerd and was soooo excited to get to see these ruins.
It is correct that there is no way down the gorge and you can only visit by looking down from the street but I thought it was well worth the look.
The sidewalk you can look down is quite narrow and the street is quite busy, being essentially the main thoroughfare from the main square, Piazza Tasso. However, there is a wider spot, with the best view, from the end of the street by the hotel parking garage. There aren't a lot of cars there so I'd recommend this spot.
I really do wish you could go down there and of course my intrusive thoughts went wild but it was well worth the look down.
