Solfatara
Solfatara is a shallow volcanic crater at Pozzuoli, near Naples, part of the Phlegraean Fields volcanic area. It is a volcano, which emits jets of steam with sulfurous fumes. The name comes from the Latin, Sulpha terra, "land of sulfur", or "sulfur earth". It was formed around 4000 years ago and last erupted in 1198 with what was probably a phreatic eruption – an explosive steam-driven eruption caused when groundwater interacts with magma. The crater floor was a popular tourist attraction until 2017, as it has many fumaroles and mud pools. The area is well known for its bradyseism. The vapours...
What it is
Solfatara is a shallow volcanic crater at Pozzuoli, part of the wider Phlegraean Fields volcanic area west of Naples. It last erupted around 1198, likely in a phreatic (steam-driven) event, and the ground still shows that activity: fumaroles hissing sulfurous steam and, historically, bubbling mud pools. The name itself comes from Latin for "land of sulfur." It's a stop for anyone curious about active volcanism up close, rather than a scenic overlook.
Getting there
Solfatara sits in Pozzuoli, west of central Naples. By car or taxi, the drive typically takes around 25-30 minutes depending on traffic. Public transport options include the Cumana rail line to Pozzuoli, followed by a short taxi or walk to the site.
Time to allow
An hour or so is usually enough to take in the crater floor and surrounding area at a walking pace.
When to go
Note that the crater floor itself has been closed to visitors since a fatal accident in 2017, so check current access before planning a visit centered on walking into the crater. Sulfur fumes are present throughout the site, which can be uncomfortable for those sensitive to strong smells.
Combine with
Solfatara is essentially inside the Phlegraean Fields volcanic area, so the two are effectively the same visit. The Vesuvius Observatory, which monitors this volcanic zone, is about 3.7km away and suits travellers interested in the science behind what they're seeing. The Cave of Dogs (2.4km) and the Bagnoli district (2.7km) are also within easy reach for a fuller day around Pozzuoli.
