Naples spa and thermal baths: the Agnano pools and Ischia’s thermal parks

Terme di Agnano: thermal baths in the city

The Terme di Agnano are the thermal complex within Naples city limits, in the western part of the city. The property belongs to Terme di Agnano SpA, which is in liquidation; the pools and caves are run by a company called TDA srl. The complex includes:

• Thermal pools: two outdoor hyperthermal pools with neck showers, at 35–40 °C, and four indoor hyperthermal whirlpool tubs at the same temperature.
• Stufe di San Germano: natural dry-heat caves, in effect volcanic saunas.
• Archeopercorsi: archaeological walks among the remains of Roman baths on the site; ask the baths for the schedule.

• Monday: closed
• Tuesday: 9:30am–midnight
• Wednesday and Thursday: 9:30am–8pm
• Friday and Saturday: 9:30am–1am

These are the general hours on the official site; individual areas may keep their own hours, so check the ones for the part you want.

Contacts: pools 081 230 5846, caves and beauty centre 081 2158349. Agnano is one stop from the Città della Scienza science centre in Bagnoli, so you could do the museum in the morning and the baths in the afternoon; just check both places’ closing days first.

Thermal Ischia: Poseidon Gardens and Negombo

Ischia is the spa island of the Bay of Naples, and its large thermal parks combine pools at different temperatures with gardens by the sea. Two names stand out.

Poseidon Gardens (Giardini Poseidon Terme, Forio)

On the Baia di Citara in Forio. In season the park opens 9am–7pm, closing at 6pm from October.

• Full day €50; afternoon €45 (from 1pm, or 12:30pm from October).
• Ages 4–11 half price, 0–3 free; children aren’t allowed in the thermal area.
• Evening walk 6–7pm without the pools: €8.
• €5 cash deposit for the wristband; entry can’t be booked.

Negombo (Lacco Ameno)

On the Baia di San Montano in Lacco Ameno, with a beach as well as thermal pools. A full day runs 8:30am–7pm.

• Adult with umbrella and lounger: €55 in low season (until early July and from mid-September), €70 in high season (early July to mid-September).
• Half day €40 or €50, afternoon €30 or €35, depending on the season.
• Children between 1 m and 1.40 m €28–30; under 1.40 m they can’t use the thermal pools.
• Visit from 5:30pm without the pools: €10.
• Full days can be booked online up to 3 days ahead, until 6pm the day before; otherwise pay at the gate if there’s space.

Getting from Naples to Ischia

• Hydrofoils from Molo Beverello: Alilauro in about 50 minutes, Caremar in about 55–65 minutes. The Caremar hydrofoil costs €21.60.
• Ferries from Calata Porta di Massa: Caremar in about 95–100 minutes all year (€14.80), Medmar in about 90 minutes from April to October.
• Arrival ports: Ischia Porto and Casamicciola; some Beverello lines also call at Forio, which is handy for Poseidon Gardens.

From the port you still need local transport or a taxi to reach the parks. Ischia doesn’t charge the landing fee that Capri does. Timetables and alternatives are on our Capri, Amalfi and Ischia page; for reaching the port from the centre, see getting around Naples.

Agnano or Ischia: which to choose

• You have half a day or an evening: Agnano. You get there by metro, and on Tuesdays, Fridays and Saturdays you can stay late.
• You have a full day between spring and October: Ischia. The trip adds about two hours of travel there and back, plus the ferry fare (from about €30 to over €40 per person return), but a park overlooking the sea is a different experience.
• You’re travelling with young children: read the Ischia parks’ rules carefully, as they restrict little ones’ access to the thermal pools.
• You’re travelling out of season: the Ischia parks close in winter, so Agnano is your main option.

Practical tips for a day at the baths

• Bring a swimsuit, flip-flops, a towel and a water bottle: at 35–40 °C you dehydrate quickly.
• Alternate hot pools with breaks in the shade, and don’t stay long in the caves or the hottest pools.
• On Ischia, keep a few euros in cash for deposits and small purchases.
• If you’re taking a ferry, check the last boat back before buying an afternoon ticket.

Booking a spa or thermal baths in Naples

For a spa or thermal baths in Naples, the official channel is the best one: the Terme di Agnano online shop, the Negombo website for full days, and the Poseidon Gardens ticket desk, which doesn’t take bookings. Our partners, Tiqets and GetYourGuide, don’t sell any thermal entry we’ve verified, so we don’t present them as if they did: they’re useful for the rest of your trip, from excursions to city tours, as you’ll see in things to do in Naples.

We are an independent guide: if you book through the Tiqets or GetYourGuide links on this page we may earn a commission, at no extra cost to you.
