Guided Adventure Tours in Naples

October 6, 2026

Underground, up the volcano, out to sea

Three adventures sit within an hour of central Naples: a descent into the tunnels under the old town, a walk to the rim of Vesuvius, and a day on a boat around Capri. Each is sold as a guided tour, but only two of them really need a guide. Knowing which saves money and a lot of waiting around.

Under the city: always guided

Napoli Sotterranea is the one you cannot do alone, because the tunnels are only open on a guided visit. Tours leave every hour from 10:00 to 18:00, in English and Italian, from Piazza San Gaetano 69 on Via dei Tribunali. A guide leads you about 40 metres down a 136-step staircase into Greek and Roman cisterns, and along conduits so narrow that you carry a candle to light the way. The route also takes in air-raid shelters used during the Second World War.

Groups of fewer than 10 can simply turn up, which makes this the easiest adventure in Naples to fit into a free hour. Expect to pay around EUR12 to EUR15. Departure times are on the Napoli Sotterranea visiting hours page . This tour starts in the old centre, so do not confuse it with the Toledo metro station, whose mosaic ceiling is a separate sight on a metro ticket.

Vesuvius: a guide is optional

The crater trail is short and clearly marked, so you can walk it without a guide. What a tour really sells is the transport: the trailhead is about an hour from Naples by train and shuttle, and a group minibus removes the connections. If that convenience is worth it to you, compare Vesuvius tours on GetYourGuide and check that the crater ticket is included.

If you go alone, the ticket is the only hard part. It is sold online, in your name, for a timed slot, at EUR10 plus a booking fee; there is no booth on the mountain. October hours are 9:00 to 16:00, and the trail closes on orange weather alerts with an automatic refund. Book on the national park’s Gran Cono page .

At sea: book the boat

A shared full-day boat trip from Naples is the simplest way to see Capri’s coast from the water. These run around EUR85 to EUR160 a person and usually include the Faraglioni rocks, swimming stops and a few hours ashore. Prices vary with the boat and what is included, so compare Capri boat days on Viator before you choose.

The Blue Grotto is the catch. Entry costs about EUR18 to EUR19, paid in cash, and the grotto closes whenever the sea is rough and normally through the winter. Treat it as a bonus, not the reason for the trip. If you would rather go under your own steam, the hydrofoil from Molo Beverello takes about 50 minutes and costs roughly EUR21 to EUR30 each way, and the chairlift up Monte Solaro gives the island’s best view.

For a private group with money to spend, a speedboat charter along the Gulf runs roughly EUR700 to EUR1,800 for the day.

Before you book

On any Vesuvius tour, confirm the price covers the named crater ticket; it cannot be bought at the top.
Pickpockets target the Circumvesuviana and Piazza Garibaldi, so keep valuables zipped.
Wear shoes with grip for the 136 steps and the cinder path, and pack a swimsuit for the boat.

The verdict: pay for a guide underground and at sea, and do the volcano yourself. Take the 10:00 Sotterranea tour on a day you are in the old centre anyway, and keep the boat for the calmest forecast of the week.
