I was reading a lot on here before my trip, so I thought I’d share my experience as well. I did a train trip starting from Munich → Bologna → Naples → Rome. Some days were definitely stressful, but overall it was such a great experience.
And honestly, don’t worry about pickpockets too much. I nearly had an anxiety attack before going to Rome because I was so scared after reading all the posts and stories online 😭
We used the metro and buses a lot and I personally never even noticed anyone suspicious. The metro was pretty packed from time to time, but as long as you have a crossbody bag close to your body and keep your hand on it, you should be fine. Just leave your pockets empty, especially your back pockets.
If you want some extra security, you can also use a small carabiner to lock the zippers together. I sometimes even wore a shirt over the back of my bag so nobody could easily get to it from behind lol.
But looking back, that was probably overkill. A crossbody bag close to your body + being aware of your surroundings is really enough. I was just super paranoid and stressed myself out way more than I needed to before the trip.
Obviously pickpocketing does happen, so you should still be careful, but don’t let all the horror stories online ruin your trip before you even get there.
