Mike, I was trying to find the date and details of the Allied bombing and found some article that says tourism is relatively new to Cinque Terre. 1970's-80's mostly Italians, then some guy named Rick Steve's wrote about it in the 90's and American backpackers started flocking in. Covid certainly hit them hard, but sounds like restaurants etc opened at 50% capacity in June. It is one of our favorite travel memories, we hiked through 4 villages and because the trail was closed we had to train to the last. Tom and Ellen can probably back me up, but it's amazingly beautiful and peaceful. This pic is from Bar Gabbiano on the trail between Vernazza and Corniglia, you can imagine how that hike was from village to village, my wife is looking down at Corniglia, great hike!
