Spend half a day visiting Mount Vesuvius.
Vesuvius is a somma-stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 km (5.6 mi) east of Naples and a short distance from the shore. It is one of several volcanoes which form the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier and originally much higher structure.
Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii, Herculaneum, Oplontis and Stabiae, as well as several other settlements. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of 33 km (21 mi), spewing molten rock and pulverized pumice. More than 1,000 people died in the eruption, but exact numbers are unknown. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus.
Vesuvius has erupted many times since and is the only volcano on the European mainland to have erupted within the last hundred years. Today, it is regarded as one of the most dangerous volcanoes in the world because of the population of 3,000,000 people living nearby, making it the most densely populated volcanic region in the world, as well as its tendency towards violent, explosive eruptions of the Plinian type.
After a convenient pickup from your hotel,or designated meeting point, enjoy a scenic drive through Vesuvius National Park, centered on the active volcano and its most ancient (now inactive) crater, Monte Somma. It houses 612 vegetable species and 227 wildlife ones. The tour takes you right up to exploring the crater, where your guide tells you about the mountain's geology and its infamous eruption in 79 AD.
On your way back to Sorrento, stop in Vico Equense for a visit to the Mineralogy Museum of Campania. Here, you can see minerals, meteorites, prehistoric fossils, gems, and even dinosaur's eggs collected from the region around the mountain.
