I realize this forum is not used often, yet I like to post an opinion about Vico Equense for the benefit of those searching for information about this lovely town. We stayed here for 8 nights in the historical center, about a couple of hundred meters away from the central piazza.
The reason we chose Vico as our base for exploring the surrounding area is that, although we are not particularly adventure travelers, we do not like places entirely overtaken by tourism. Vico is a town not much mentioned in travel guides. And since the main road from Naples to Sorrento runs through a tunnel underneath the town, many may not even be aware of its existence.
We experienced Vico as a safe, relatively clean and pretty town, perched on its own cliffs not unlike Sorrento. The Cento Storico, with a nice little piazza, a castle and a network of narrow streets and alleys, is very picturesque. About four or five evenings we chose to dine in Vico, mostly on one of the patios at Piazza Umberto. We would sit here for several hours among mostly locals, just absorbing the vibrant evening life of an Italian town. A police car would park in the center of the square near the fountain and the constable, who seemed to know everyone, would spend his time having friendly chats with those passing by. We dined two evenings in Sorrento, once at Piazza Tasso and once at Marina Piccola, but neither gave us the same sense of being in Italy like we experienced in Vico Equense.
Vico has two beaches. One at the west end and one on the east. Both are about a 10 to 15 minute steep walk down from the old town center. The west one is a bit more developed with a few restaurants and bus service. We spent a day on the pretty east beach, among the small fishing boats and pleasure crafts. At this beach we found communicating more challenging, since no one spoke English, until we found someone who spoke some German, a language we also speak with limitations. At the hotel and in the restaurants we got by quite well with our English.
From Vico we daily commuted with the Circumvesuviana train to the places we wanted to visit. Trains run about every half hour. 11 minutes at 1,30 Euro to Sorrento. We also trained to Naples for about 5 Euros. From Sorrento we took ferries to visit Positano, Amalfi, Ravello and Capri.
One warning about the trains though: Twice during our stay the train service halted for a few hours due to strikes. Once unannounced in the late afternoon and evening and once pre-announced for four hours in the morning. And other than the Naples airport bus, there is no bus service out of Vico. So if you are caught in a strike, a taxi is the only alternative (40 Euros to Sorrento). And the wait for a taxi may be long. But for us, that was the only negative for Vico Equense. After having visited Sorrento, the Amalfi Coast and Capri, we were certainly glad to have selected Vico as our base.
