Overview

About Terme Stufe di Nerone

Terme Stufe di Nerone, Italy is a large thermal park in the Phlegraean Fields (Campi Flegrei), near Lago Lucrino between Bacoli and Pozzuoli, approximately 15 kilometres west of Naples. Known since at least the 2nd century BC as the Balneum Silvianae, the site was frequented by Roman figures including Horace, Cicero, and Nero. The springs were buried by the 1538 Monte Nuovo eruption and rediscovered in the 18th century. The modern complex opened in 1973.

The park has approximately 20 natural thermal springs forming two lakes at 38 to 58 degrees. The main source flows at 74 to 80 degrees. The water is salsobromoiodic hyperthermal with anti-inflammatory properties suited to respiratory, musculoskeletal, and dermatological conditions. The defining feature is two natural cave saunas carved from volcanic rock at 52 to 55 degrees, used for antroterapia and as natural Turkish baths.

Outdoor facilities include a semi-Olympic pool, two more outdoor pools, a mud pool, a children's pool, and a solarium. Indoors: two pools, sauna, Kneipp path, two Jacuzzi baths, and hydromassage. Green volcanic clay for body application is available, and a restaurant and bar serve on site.

Safety & Etiquette

Terme Stufe di Nerone Safety Tips

Terme Stufe di Nerone is a managed thermal park with staff on site during all opening hours. The main spring flows at 74 to 80 degrees Celsius; do not approach or enter water near active spring vents, as scalding is a risk. Pool water is maintained at safe bathing temperatures, but always test before entering and move away from areas where the water feels unusually hot. The natural cave saunas operate at 52 to 55 degrees; limit sessions in the stufe to short intervals and exit if you feel dizzy, overheated, or uncomfortable. Alternate between the caves and cooler areas to avoid heat stress.

Those with cardiovascular conditions, low blood pressure, or respiratory sensitivity to sulphur should consult a doctor before visiting. The water is sulphurous and the smell is strong throughout the park, particularly near the spring vents and lake areas. The green clay should not be left on skin for longer than the recommended period; follow staff guidance. Do not wear silver jewellery in sulphurous water.

A swim cap is mandatory in all pools; purchase on site for 2 euros if needed. Outside food is not permitted; the restaurant and bar are available on site. The car park is paid and separate from the entrance fee. The complex is closed on 1 January, Easter Sunday, Easter Monday, 25 December, and 26 December. Opening hours vary by season and day of week; check termestufedinerone.it before visiting. Single-visit entry is only available online in advance; walk-in entry requires purchasing a minimum six-visit pass.

What is Terme Stufe di Nerone?

What are the natural cave saunas at Stufe di Nerone?

The stufe are two natural caves carved directly from the volcanic rock of the Phlegraean Fields, with interior temperatures of 52 to 55 degrees Celsius. Thermal steam from the underground springs fills the caves naturally, creating an environment similar to a Turkish bath without any mechanical heating. They are used for antroterapia (cave therapy), which benefits respiratory and skin conditions, and for general relaxation. Most visitors move between the cave and the cooler pools in cycles. The caves are the defining feature that gives the complex its name and its historical identity.

Is Stufe di Nerone historically connected to Roman times?

Yes. The site is one of the oldest thermal destinations in Italy. The baths were known in the Roman Republic era under the name Balneum Silvianae and were frequented by prominent figures including Horace, Cicero, Julius Caesar, and Nero. The Phlegraean Fields surrounding the park were a favourite retreat of the Roman aristocracy and were described by multiple Roman writers. The springs were buried and lost after the eruption of Monte Nuovo in 1538 and rediscovered during the 18th century. A Norman thermal establishment with 120 baths was built on the site around the year 1000 AD. The modern complex was built in 1973 on the foundations of these ancient structures, some of which are still partially visible.
