Will be in Orvieto for a couple days and would like to get tickets to the underground. The information I've found is a bit confusing so looking for feedback/info from those in the know.
There is a Orvieto Underground website and a Pozzo della Cava website which look different, but seem to have some overlap of sites in the tour.
Are these 2 totally different places that need to toured separately or are they overlapped somehow with cross-site tickets? Is one better than the other?
Thanks
