Before you go: bradyseism
Bradyseism is the slow movement of the ground in this volcanic area, and it can cause earthquakes. The ground has been rising since 2005.
The alert level is yellow, phase 2 of attention (Italian Civil Protection website, consulted on 1 November 2026). The INGV bulletin of 27 October 2026 reports uplift of about 10 mm a month.
There were earthquake swarms in 2025 and 2026. The magnitude 4.7 earthquake of 31 July 2026 caused damage in Pozzuoli. The Park closed all its sites for checks, then reopened them in stages during August.
Where to check:
What to do in an earthquake, according to the Civil Protection:
- Indoors: move away from the middle of the room and shelter next to a load-bearing wall, under a beam or under a sturdy table. Don't rush outside: wait for the shaking to stop.
- Outdoors: move away from buildings, trees, street lamps and power lines.
- Afterwards: don't use lifts, take care on stairs, and limit phone and car use. Go to the assembly areas. In an emergency call 112.
What to see
- Flavian Amphitheatre, Pozzuoli: about 1 hour.
- Baths of Baia: large Roman terraces on the hillside, about 1.5 hours.
- Baia Castle and the Phlegraean Fields Museum: 9:00-18:30, last entry 17:30.
- Sunken Baia: Roman remains under the sea, seen with an authorised operator. List on the official website.
- Cumae: the acropolis and the Cave of the Sibyl, maximum 25 people at a time. The Park reports no closure of the cave.
- Piscina Mirabilis, Bacoli: a Roman cistern, accompanied entry with a helmet. Ticket about €5. CoopCulture gives Friday, Saturday and Sunday 10:00-15:30 until 31 March 2027, but the same page lists other days: call +39 081 0105665.
- Lake Avernus: a walk around the lake. The Temple of Apollo opens only on special occasions.
- Lake Fusaro: the Casina Vanvitelliana stands on the water. For visits inside, ask the Pro Loco di Bacoli.
Tip: go on a Friday, Saturday or Sunday. Those are the days when Baia, Cumae, the Amphitheatre and Piscina Mirabilis should all be open.

- Circuito flegreo: about €10, reduced about €5. Valid for 3 days at the Amphitheatre, Baths of Baia, Baia Castle and Cumae, and booking is required.

Getting there
- Cumana train from Montesanto: Pozzuoli 20-30 minutes, Lucrino about 30, Fusaro about 40. The full line has been running again since 11 September 2026, with a new Pozzuoli station.
- Line 2: suspended since June 2026 between Campi Flegrei and Pozzuoli Solfatara, with replacement buses about every 15 minutes. The closure is due to CO2 in the tunnel: test runs were under way in late October, but there is no reopening date.
- EAV buses: needed for Cumae and Bacoli, with few departures. Use the EAV journey planner.
For the Baths of Baia, the Park suggests Fusaro or Lucrino station, then a bus or about 1 km on foot.
