Mount Vesuvius facts at a glance
Mount Vesuvius rises beside the Bay of Naples. The cone visitors climb is the Gran Cono, reached on trail 5, Il Gran Cono. Around it runs Monte Somma, and the two belong to one volcanic complex, Somma-Vesuvius.
The volcano is monitored by the INGV Osservatorio Vesuviano. Its last historical eruption was in 1944, and the record reaches back to the eruption of 79 AD. See the eruption history for that story.

Guided hikes to the crater
Crater tickets, guided hikes and day trips from Naples, Pompeii and Sorrento, with live prices and availability. Check each listing for whether it includes a guide, an audio guide or transport.
The Gran Cono and Monte Somma
Vesuvius and Monte Somma are two parts of the same structure. The Somma-Vesuvius complex is why the mountain has a cone in front and a ridge behind. The paths on the two parts are not interchangeable, so a hike on one is not a hike on the other.
What the crater trail allows
The walkable section of trail 5 ends at the released areas. You cannot walk a full loop around the crater rim, climb the closed summit edge or go into the crater. The high northern and eastern rim stays closed. A guide or a transfer does not lift a barrier.

Monitoring and the red zone
The INGV Osservatorio Vesuviano watches the volcano. A quiet volcano is not an extinct one, and "last erupted in 1944" is not a promise about the future. This page gives no forecast. Current alert information belongs to dated official notices.
Civil protection keeps emergency plans for the area, including a red zone. They are precautionary. They do not mean an evacuation is ordered, and no fixed warning time or personal escape time follows from them.
Entry ticket and booking
The crater trail is sold by time slot with limited capacity, under a park decision of 29 June 2026. A late booking is not a guaranteed ticket, and there is no regular ticket desk at the crater entrance. Read the ticket terms in the shop you use before you pay, and carry the identity details or proof the ticket asks for. See Vesuvius tickets for the full picture.
Practical facts for the walk
- The path is steep, sunny and dusty, and the wind is strong at times. Wear sturdy shoes and carry water.
- The park can close the trail when weather orders require it, so check before you leave.
- Published entry hours start at 09:00. The closing hour changes with the season. See opening hours.
