My husband and I stayed in manarola and on Sunday we hiked from manarola to monterosso and back. It took us all day with lunch and coffee breaks. The last trail is still closed and so is the manarola to corniglia. We were able to take another trail a little higher and harder. I think that part of the trail took at least 2 hours. It was definitely worth it though. I wanted to post an update since I had a hard time finding much info.
