So, unpopular opinion here, but I’d tell you to skip it raining or no. If you’re going from Bomerano to Nochelle as most do, it’s at least half your day. It’s not as easy hiking as it sounds. A good stretch of it is uneven, rocky ground. If it is raining, then a definite no. About the last third is on forested switchbacks and will be muddy. Long story short: I felt prepared, was sort of underwhelmed, and was generally exhausted by the end of it. My only regret in 10 days in Italy. I could name ten things I would have done with that day instead.
“Path of the Gods” sounds amazing. Whoever named it was brilliant because I would not have gone through the effort to hike “Trail #5” while on vacation. Sure the views are amazing, but the views are amazing EVERYWHERE there. I had just as satisfying views while having lunch in Ravello and on the ferry. Unless you’re avid hikers with time on your hands, it’s not worth it.
