With kids, St Peter's Dome Climb (Cupola) needs the right timing and tolerance.
Worth it for Rome's most dramatic climb-and-view sequence: an interior balcony over the basilica, then a tight spiral to the city panorama. The catch is physical — even the €22 lift ticket leaves 320 narrow steps — so skip it if claustrophobia, vertigo, heat or limited mobility will overwhelm the payoff.
