I fell in love with beautiful Naples from the upper floor of this bus. It was the hop on and off variety with a ticket valid for 24 hours. However as we were on a cruise stopover we just did the full tour and took in the total beauty of the bay of Naples with the forbidding, yet strangely beautiful sight, of Vesuvius overlooking the bay. The commentary was informative and interesting and the route took in many breath-taking natural sights as well as lots of interesting and wonderful buildings. Definitely a must if you have a few hours to spare!!!
