You can stand on the rim of the volcano that buried Pompeii and look straight down into the crater. It takes about half a day, the walk itself is under an hour, and on a clear day the view runs from Naples across the whole bay to Capri. It is also, by a considerable margin, the most dangerous volcano on Earth — not because of what it does, but because of how many people live on it.
The Mountain That Killed Pompeii
Vesuvius is a somma-stratovolcano: the jagged ridge you see to the north, Monte Somma, is the remnant wall of a much older, larger cone. The younger cone of Vesuvius grew inside it. The valley between them, the Valle del Gigante, marks the scale of the earlier collapse.
The AD 79 eruption is the one everyone knows. It ejected a column of pumice and ash many kilometres high — the type of event now called Plinian, after Pliny the Younger, who watched it from across the bay and wrote the only eyewitness account we have. His uncle, Pliny the Elder, sailed toward the eruption to mount a rescue and died on the shore.
That column collapsed into the pyroclastic surges that destroyed Herculaneum and finished Pompeii. Recent work on inscriptions found at Pompeii has pushed the likely date from the traditional 24 August toward the autumn of AD 79 — supported by the autumn fruit and heavier clothing found at the sites.
It is not extinct. Vesuvius has erupted many times since, most recently in March 1944, during the Allied campaign in Italy — an eruption filmed by Allied airmen and which destroyed dozens of aircraft at a nearby airfield. It has been quiet since, which is not the same as safe. Roughly 600,000 people live inside the designated red zone, and the evacuation plan for it is one of the largest civil-protection undertakings in Europe.
The Crater Hike, Honestly Described
This is a well-managed tourist walk, not mountaineering — but it is not nothing.
- The road takes you most of the way. Vehicles reach a car park at roughly 1,000 m; the summit is about 1,281 m and changes slightly with eruptions.
- The walk is about 20–30 minutes each way up a broad switchback track of loose volcanic gravel. It is steep in places and the footing slides. Trainers are fine; sandals are not.
- Booking is required in advance for the Vesuvius National Park crater path, with timed entry. Turning up unbooked in season is a real risk.
- You walk part of the way around the rim, with the crater on one side — a grey, steaming bowl a few hundred metres across, with visible fumaroles — and the bay on the other.
- Weather closes it. Cloud, high wind or storms shut the path with no notice, and cloud can hide the entire view. Build a spare day in if the view is the point.
- Take water and sun cover. There is no shade above the car park.
Getting There
The usual approach is the Circumvesuviana train to Ercolano Scavi, then a dedicated shuttle bus up the mountain. This makes the obvious pairing a single day: Herculaneum in the morning, Vesuvius in the afternoon — the ruins and the cause, in that order, which is the right order.
Vesuvius Crater Tours & Combined Trips
Most tours bundle transport, park entry and a guide — and many combine Vesuvius with Pompeii or Herculaneum in one day, which solves the awkward shuttle logistics.

Frequently Asked Questions
How hard is the Mount Vesuvius crater hike?
Moderate but short. Vehicles reach about 1,000 m and the walk to the rim takes 20-30 minutes each way on a steep track of loose volcanic gravel. Wear trainers or boots – the footing slides – and carry water, as there is no shade.
Do you need to book Vesuvius in advance?
Yes. The national park crater path uses advance booking with timed entry, and the path closes at short notice in bad weather. Build in a spare day if the view matters to you.
Is Vesuvius still active?
Yes. Its most recent eruption was in March 1944. It is currently quiet but closely monitored, and roughly 600,000 people live within the designated red zone.
Did Pompeii really fall on 24 August AD 79?
That is the traditional date from Pliny the Younger’s account, but inscriptional evidence found at Pompeii, along with autumn fruit and heavier clothing at the sites, points to an autumn eruption instead.
