Mount Vesuvius last erupted in March 1944, destroying three villages and burying American bomber aircraft stationed at the base. The 1,281-metre stratovolcano remains the only active volcano on mainland Europe, its Gran Cono summit crater measuring 230 metres deep and 450 metres across.
Seismic monitoring stations ring the caldera, feeding data to the Osservatorio Vesuviano, established in 1841 as the world's first volcanological observatory.
The mountain's notoriety rests on a single event: the AD 79 eruption that buried Pompeii and Herculaneum under six metres of pumice and ash. Pliny the Younger documented the 19-hour Plinian eruption from Misenum, describing a stone-pine cloud that rose 33 kilometres before collapsing in pyroclastic surges. Excavations begun in 1748 revealed carbonised wooden beams, frescoed villas, and plaster casts of victims frozen mid-flight, drawing two million visitors annually to the archaeological park below.
Today the volcano anchors Parco Nazionale del Vesuvio, a 135-square-kilometre reserve protecting Mediterranean maquis, holm oak, and 906 plant species. The summit trail, a paved 900-metre path ascending from the Quota 1000 car park, crosses lava beds from the 1944 flow and offers unobstructed views across the Bay of Naples to Capri. Fumaroles steam near the crater rim, where sulphur deposits tint the rock yellow and volcanologists measure gas emissions weekly. The conservation fee, set at 10 euros and collected via mandatory online booking, funds trail maintenance and geological monitoring. Most mount vesuvius tour from naples options depart between 08:00 and 09:30, allowing summit arrival before midday heat and cloud build-up obscure the caldera floor. Combined itineraries pair the crater hike with Pompeii, allocating three hours to the ruins and 90 minutes on Vesuvius. Dedicated crater-only excursions from Naples return within five hours, including the 30-minute shuttle from the park entrance to the trailhead. The mountain closes only in severe weather; the official site posts real-time alerts and seasonal hours, extended to 18:00 in summer and reduced to 15:00 from November through February.
