You need at least one week to explore this region properly. Where you stay and how you get about partly depends on when you visit. If you fancy a laid back vacation in high season then consider Sorrento and forget the idea of car rental - the roads are narrow, the traffic insane, and parking can be a nightmare, but you need not worry as the main towns have boat shuttles between them, and there is good public transport to Pompeii.
My son and I wanted a different experience so we opted for April, rented a car, and stayed in the small village of Ravello (images above and below - clicking on any image shows the location). At this time of year the weather is more pleasant and the roads quieter. In terms of Ravello, it is very laid back and provides good access to the other towns of the Amalfi coast. The road heading north from Ravello takes you towards Pompeii, Herculaneum and Vesuvius.
Travelling from West to East along the Amalfi coastline are a string of fabled towns reading like a Hollywood cast list:
Going between the towns of Bomerano and Nocelle, the Path of the Gods is a 6.5 km hike (2-4 hours) that takes you high above Positano and offers stunning views of the Amalfi Coast. I recommend starting out early in the morning to avoid the heat (there is little shade) and crowds.
It is best to start from Bomerano as the route runs gently downhill with magnificent views of the coastline and the island of Capri. You can drive to Bomerano but that means having to hike back up, as such a better option is to get a bus or taxi to Bomerano, hike down to Nocello, and then extend your walk by taking the 1700 steps down to Positano (image below) to enjoy the rest of your day.
For most of us mere mortals, the Island of Capri is a day trip - with steep cliffs rising majestically from an impossibly blue sea, elegant villas dripping with wisteria, and world-class shopping, Capri is long a preserve of celebrities who anchor their yachts in Marina Grande.
You can easily reach Carpi by ferry, or you can take a boat tour and include other stops such as the Blue Grotto - the grotto’s extraordinary optical effect is created by the sunlight bouncing on the cave walls, producing electric-blue water that seems to glow.
There are two separate towns on Capri. Most visitors only visit Capri town, with its well-known attractions such as the Piazzetta, Marina Piccola and the famous shopping streets. The other town, Anacapri is a short bus or taxi ride away, from here you can take the chair lift to the top of Monte Solaro, which at 589 metres is the high point of Capri.
Pompeii is a UNESCO Heritage Site, which means it is protected and preserved, offering a complete vision of an ancient town, from the public to private life.
Pompeii gets hot in the late spring and summer so getting here early is advisable, as is taking your own food .... the food on offer isn't great. Pompeii can be reached by car, bus, or train. Given the size of Pompeii it is possible to spend anywhere from a few hours to a full day here. If you are interested in history then I am sure a guided tour would be your best bet. My son and I were satisfied with our own made up tour that took us around some of the highlights:
Don't blame me if you get lost - a strong sense of direction has never been one of my strong points!
We visited both Pompeii and Herculaneum, if you have time to do only one I recommend Pompeii.
Herculaneum, which is better preserved than Pompeii, is a smaller, compact site that offers a window mainly into ancient private life, most of which can be seen in approximately two hours.
Because few human remains were found during early excavations, it was assumed that most of the inhabitants had succeeded in escaping toward Naples. In the 1980s, however, excavations at the ancient shoreline of the Bay of Naples (an area that is now inland) uncovered more than 120 human skeletons, suggesting that numerous additional inhabitants had perished while attempting to escape.
A trip up Mount Vesuvius requires on average half a day. Public roads take you up to 800 meters above sea level, where there is an unstaffed parking area. From here it is quite a tough walk up to the ticket office, after which there is a further hike to the summit at 1,281 metres - a better option is to take the inexpensive shuttle that runs from the car park to the ticket office.
At the time of writing this article you had to pay in advance for both the parking (https://parkingsuvio.it/) and for the entrance into Vesuvius, not literally, but from the ticket office (https://www.vivaticket.com/it/ticket/visita-guidata-al-gran-cono-del-vesuvio/79785).
Mount Vesuvius has erupted about three dozen times since 79 A.D., most recently in 1944. Vesuvius remains one of the most dangerous volcanoes in the world - firstly because it a stratovolcano, a type known for its explosive eruptions, and secondly because the city of Naples, with a population of over 3 million people is located just 12 kilometres away (aerial image below). Another 600,000 people live even closer, in the red zone (a distance of 10 kilometres from the crater) where they are in the direct path of deadly pyroclastic flows. Mount Vesuvius will erupt again, but no one knows when.
