Thermal Springs in Turkey: Where to Go and What to Ask
What thermal means in Türkiye, how to check a spa before you pay, the places the ministries list, Pamukkale hours and a message to send in Turkish.
Table of Contents
Some thermal spas in Türkiye are treatment places with a doctor on site, and some are hotels with a warm pool. The two follow different rules, and the regulation does not say who may swim when or what a child pays. This page sets out what the Health Ministry and the Ministry of Culture and Tourism say, then helps you write to the spa before you go.
In short · checked 22 October 2026
Know what you are booking, then ask the spa.
- Thermal: the spa regulation counts water as thermal when it is 20 °C or warmer where it comes out.
- Treatment: a spa that offers treatment needs a Health Ministry operating permit, a specialist doctor and health staff who work full time. A hotel’s warm pool is not necessarily one.
- Pamukkale: open every day, 08:00–18:00. The ticket office and the walking entrance close at 17:00. Foreign visitors pay €30 for one ticket.
- Not covered: the regulation says nothing about women-only or mixed hours, children’s ages or prices. Each spa decides, so ask. The pools below write the message in Turkish.

Merhaba, Hafta sonu 2 yetişkin için günübirlik giriş bilgisi almak istiyorum. Giriş ücretini ve çalışma saatlerini yazılı olarak bildirir misiniz? Havlu, bornoz ve terlik ücrete dahil mi? Havuzlar karma mı, yoksa kadınlar ve erkekler için ayrı saatler var mı? Teşekkür ederim.
What it says
Hello, I would like day-visit entry information. When: the weekend. Adults: 2. Could you tell me the entry price and the opening hours in writing? Are the towel, bathrobe and slippers included in the price? Are the pools mixed, or are there separate hours for women and men? Thank you.
Replace the words in [brackets] with your own. Check every detail before you send it.
What “thermal” means in the regulation
The Health Ministry’s spa regulation defines the words. Thermal water is water that is 20 °C or warmer where it comes out. Mineral water holds at least 1 gram of dissolved minerals in every litre. Thermomineral water is mineral water that is also 20 °C or warmer at the outlet. A spa (kaplıca) is a place where such water is offered to the public.
A temperature, not a promise
That is a measure of the water, not a claim about health. The General Directorate of Mineral Research and Exploration counts about 1,000 natural hot-water outlets across Türkiye, at many temperatures. Nine in ten of these resources are low or medium temperature, which the directorate says suits direct use such as heating and thermal tourism. About 78% of the potential lies in western Anatolia.

Check the spa before you pay
A treatment spa and a hotel with a warm pool are not the same thing. The Health Ministry describes a spa as a place where natural treatment elements are used for health, and its regulation sets the rules for such a place. These are the things to look for.
- A permit for that spa. The provincial health directorates give a facility permit before a spa is built and an operating permit after. The operating permit names the person, the address and the business; if any of them changes, the permit ends.
- A doctor and health staff. The regulation requires a specialist doctor and health staff, and the health staff work full time.
- Regular checks. The ministry says treatment spas are inspected every three months by the provincial health directorates and once a year by ministry staff. Water taken where it is used is tested for germs every three months.
What you can see at a treatment pool
- A shower and a foot-disinfection channel to pass through before the pool.
- Steps with handrails, and a depth of 150 cm at most.
- At least 3 m² of floor area in the pool for each person.
- Fresh water added at 1.5 litres per user per hour.
- For drinking, a separate single-use cup for each person; mud is used once.
If the water holds more than 1 mg of fluoride in a litre, the spa has to post a notice. Above 2 mg a litre, the notice says the water is not suitable for children aged 0–7 to drink.
To look a spa up, use the Health Ministry’s public register of spas. If the spa is not on it, or the page does not open, ask the spa to show its permit.
Your health
If you have a medical condition, ask your doctor before you go to a spa.

Where the ministries point you
The culture and tourism directorates of four provinces list their thermal places on their own pages, with distances from the city centre. Pamukkale, in Denizli, has its own section below.
| Province | Places | What to know |
|---|---|---|
| Afyonkarahisar | Ömer and Gecek; Sandıklı Hüdai; Gazlıgöl; Heybeli | Ömer is 15 km and Gecek 16 km from the city centre, on the road to Kütahya, with city minibuses. Hüdai is 60 km away. Gazlıgöl (21 km) and Heybeli (30 km) are still visited, but they have been off the state’s list of thermal tourism centres since 2019. The directorate lists hotels with outdoor and indoor pools, children’s pools, family pools, mud baths and steam rooms. |
| Kütahya | Ilıca; Gediz (Muratdağı and Ilıcasu); Simav (Eynal, Çitgöl, Naşa); Emet (Dereli); Tavşanlı (Göbel) | The directorate names these as its six thermal tourism centres. It also lists Yoncalı, Emet, Emet Yenice and Hisarcık Esire. |
| Yalova | Termal | 12 km from the city centre, on the slope of Samanlı Dağı. The directorate gives 366 beds for the main hotel operation (checked 22 October 2026). |
| Ankara | Kızılcahamam; Haymana; Ayaş; Sincan; Sey Hamamı | The directorate gives the temperature of the water at two of them: 36–42 °C at Sincan and 43 °C at Sey Hamamı. |
| Denizli | Pamukkale | See the next section: hours, gates and the ticket. |

A day at Pamukkale (Hierapolis)
Pamukkale is the white travertine hillside in Denizli. On top of it lies Hierapolis, an ancient city founded in the 2nd century BC by Eumenes II of Pergamon. The travertines and Hierapolis together are a UNESCO World Heritage site, and the Ministry of Culture and Tourism lists the hours and the fees.
08:00–18:00Open every day
17:00The ticket office and the walking entrance close
18:00The south and north gates close
€30Foreign visitors, one ticket for the site
As the Ministry of Culture and Tourism lists them, checked 22 October 2026.
Turkish citizens can enter with the Müzekart, the museum card. The Hierapolis Archaeological Museum, next to the site, is free. The Antique Pool opens and closes separately from the site, so ask at the gate.
Plan the day
The walking entrance closes an hour before the gates, so arrive before 17:00. The site and the Antique Pool are separate stops: ask the staff at the gate which parts are open on the day you come, and what they cost.

Children, women-only hours, mixed pools
The spa regulation sets no rule on women-only or mixed hours, on the age of children or on entry prices. So each spa sets its own, and the only way to know is to ask before you go. Ask in writing and keep the reply. The pools above write that message for you in Turkish.
A hammam day has a routine of its own: see what happens, what to wear and what to say.
