Solfatara

The basics

Solfatara is the most active of the 40 or more volcanoes that comprise the Phlegrean Fields (Campi Flegrei), a volcanic area in Pozzuoli just outside Naples. Though dormant since its last eruption in 1198, the shallow crater still emits gases from deep below the earth’s crust, and its thermal waters were once believed to be therapeutic. Visit Solfatara by joining a walking or e-bike tour of the Campi Flegrei from Naples by day, or choose a night tour for a particularly dramatic view of the area’s thermal activity. The area surrounding the Campi Flegrei is known for its rich volcanic soil, perfect for planting vineyards; many Solfatara tours pair a visit to the crater with a wine tasting of local labels.

Things to know before you go

*Solfatara is particularly interesting for kids, who are thrilled with its incandescent steam jets and fumaroles. *The Phlegrean Fields are outdoors, so wear a hat, sunscreen, and comfortable shoes when visiting. *The Solfatara is located inside the Campi Flegrei park, an area of rough terrain and unstable ground. It is not accessible to wheelchair users. *There is a coffee shop, souvenir store, and playground for the kids at the park.

How to get there

Solfatara is accessible by train from Naples via the Pozzuoli-Solfatara station, but the most convenient and stress-free way to visit is by joining a tour that includes transportation to the Campi Flegrei park.

When to get there

The volcanic park is outdoors, so it’s best to avoid visiting during the worst of the midday heat. Tour in the morning or late afternoon, or join a night tour for the coolest time of day.

Geothermal Activity at Solfatara

Solfatara has two unique geothermal phenomena to witness: the condensation of steam and the rumble of the ground when a rock is dropped just right. A walk around the crater floor takes you past the main fumarole known as Bocca Grande and the mud pit known as the Fangaia, as well as a variety of other fumaroles and mofette.
