On the western rim of the Campi Flegrei, in Bacoli, sits Terme Stufe di Nerone at Via Stufe di Nerone, 45, 80070 Bacoli NA, Italy. This small thermal complex channels steam and mineral-rich waters driven by the volcanic heat of the Phlegraean Fields, offering a restorative day trip just outside Pozzuoli.
The experience here centers on thermal pools and natural steam caves hewn into tuff and volcanic deposits. A warm outdoor pool drops into shaded palms and Mediterranean macchia, while indoor pools deliver hydrojets and bubbling massage nooks. The "stufe" — natural steam rooms where volcanic gases seep through fissures into cave chambers — are the defining geological feature: humid, aromatic pockets warmed by subterranean activity. The property preserves Roman connections; locals say the springs were used by Roman elite who prized these curative waters.
A visit typically runs 2–8 hours and is thoroughly modular. Facilities include a natural sauna, internal thermal pool with hydro-massage and jets, thermal showers, an external thermal pool, warm and semi-warm indoor rooms, a thermal park with springs, loungers and lockers. The on-site bistrot serves light, seasonal bites and the spa team offers massages that pair well with a post-dip stretch. Bring swimwear, a towel or bathrobe, and your phone to scan the QR code for check‑in at Terme Stufe di Nerone. Note: food and pool gear are not included; you can add an accappatoio for €5.
This spa stands out because its heat is not produced by boilers but by the volcanic system beneath the Campi Flegrei: chemical-rich, iron‑tinged springs and steam crevices shaped in soft tuff create a softer, earthy warmth than industrial saunas. Beyond relaxation, the site is a practical launching point for exploring old volcanic coastlines, nearby craters, and the fishing towns around Pozzuoli. It’s family-friendly but regulated: no outside food, and infants must be accompanied by adults.
Practical tips: arrive 10 minutes before your slot for QR check-in; modest walking connects pools, so minimal fitness is required; water temperatures vary, so acclimate slowly. Whether you’re chasing Roman history, volcanic geology, or a low-effort recovery day after hiking the Phlegraean rim, Terme Stufe di Nerone offers a distinctly local form of wellness rooted in fire and stone. Allow two to three hours to sample pools, try the steam caves, and linger over a light lunch; the site’s compact layout means transitions are short and restorative. For history buffs, combine a spa visit with a walk around the Baia archaeological park or an evening along Pozzuoli’s waterfront to watch the sunset over the volcanic gulf. Book online in advance—sessions can sell out on weekends—and respect posted rules to protect delicate fumarolic features and fragile tuff formations. It’s an effortless, elemental local ritual.
Sessions are flexible; visitors commonly spend between 2 and 8 hours depending on treatments and meals.

Campi Flegrei Active is a Pozzuoli-based activity provider specializing in guided experiences across the Campi Flegrei volcanic area. The company offers a diverse program that includes volcanic hikes, coastal archeotrekking, thermal-bath relaxation, snorkeling, guided scuba dives, transparent-bottom boat excursions and immersive virtual tours. Each experience focuses on the distinct natural and archaeological features of the region: Monte Nuovo and Lago d'Averno for volcanic landscapes and mythic history; the Parco Archeologico Sommerso di Baia for submerged Roman ruins and mosaics; Capo Miseno for panoramic coastal trails; and local thermal springs with natural steam caves used since Roman times. Activities range from introductory options—like Discover Scuba Diving with a brief lesson and low-depth guided dives and accessible snorkeling—to certified dives that require a first-level scuba certification for deeper exploration (dives to about 14 meters are offered in the submerged park). Transparent-bottom boat tours and the Baia.Virtuale experience provide alternative ways to engage with underwater archaeology without diving. All listings are presented in Pozzuoli, Campania, and emphasize authentic local landscape, history and marine heritage. Campi Flegrei Active presents factual descriptions of each trip and practical participation requirements to help visitors choose suitable adventures in the Campi Flegrei caldera and the Gulf of Naples.
