We walked 272,162 steps during our 3-week trip through Italy. From grand landmarks to gondola workshops, we explored over 224 locations. Since most major attractions required timed-entry tickets, we planned carefully to avoid surprises, delays, or backtracking. One key strategy? We kept our personal items minimal and our bags compact.
I couldn’t find a single source that clearly outlined which bags were allowed at Italy’s most visited sites—so I created this guide based on firsthand experience. Whether you’re visiting churches, museums, or ancient ruins, here’s what worked, what we wore, and what saved us time, energy, and stress.
If you’re looking for answers to Colosseum or Vatican bag size rules, you’re in the right place.
