Exploring the splendors of Naples on half-day guiding walking tour perfect for small family groups. Take in city sights above ground, including the breathtaking Piazza Plebicito, then head underground for a stroll through the fascinating underground Borbonico Gallery. After, enjoy a delicious pizza lunch at a typical Neapolitan pizzeria. As you leave the ship and set foot on land, be sure to look up at the 13th-century Castel Nuovo, an awe-inspiring medieval structure looming over the harbor. Nearby is the equally amazing early-renaissance Triumphal Arch. During your walk, narrow streets soon give way to the massive Piazza del Plebicito, the central square and heart of the city, dominated by the magnificent red façade of the Royal Palace, the Church of San Francesco di Paola, the Teatro di San Carlo and the Galleria Umberto. Then head underneath the piazza for a walk through the Borbonico Gallery, an underground tunnel built by King Ferdinand II of Bourbon in 1853 and used as a military connection between the Royal Palace and the barracks. The Gallery includes the 17th-century Carmignana aqueduct, built on top what may have been Roman aqueduct. The Gallery also served as a WWII bomb shelter — be on the lookout for vintage cars and motorbikes left behind after the war. Back at the waterfront, discover the famous 12th-century Castle of the Egg, a 12th-century stronghold constructed by the Normans — a great photo opportunity. For lunch, stroll down to a typical Neapolitan pizzeria to savor the real thing in the city where it all began.
