Notre-Dame Cathedral

Worth it if you're into architecture or iconic sights—107k reviewers giving it 4.3 stars suggests it genuinely delivers, and the free entry means you can decide if a paid tour adds value. Skip the peak hours (basically all day in summer) if you value your sanity, and know that 727 tour options is overkill; a simple wander or one decent guided experience will do you fine.
