A group of us (sailors) went to the very top of Mt. Etna in the early seventies. The family and I were there also maybe 15-16 years ago but we could only get about half way up because of damage from eruptions. We walked the rims of several side craters...kinda of scary.
That area is like a lunar landscape...incredible though.
What’s also weird is that halfway up there is a coffee shop selling food and chochkes. A nun, wearing the old-fashioned habit was there, with a group of school kids!
