They are all on the [map of resorts and thermal baths](https://peplaiuri.ro/en/map?categorie=statiuni-si-bai-termale) too.

## Thermal baths in Romania: the list and the map

The table covers all the resorts and baths with thermal and mineral waters on the site, by region, with the data from their pages. "Water temperature" is the one published for the springs or boreholes; where the water is cooled or heated for the pools, the pool temperature is given too. "Where you bathe" says what you will find, not the opening hours: hours and prices change and are on each resort's page. Where no temperature is given, the page does not publish one, and the water is usually used cold, for drinking cures or for baths in the treatment centres.

The [Resorts and thermal baths](https://peplaiuri.ro/en/resorts-and-thermal-baths) category also includes 17 mountain resorts without mineral waters, such as Poiana Brașov, Sinaia or Păltiniș; they are in the [guide to ski slopes](https://peplaiuri.ro/en/guides/partii-de-schi-romania). The salt baths and the seaside resorts are at the end of the guide, separately.

They are all on the [map of resorts and thermal baths](https://peplaiuri.ro/en/map?categorie=statiuni-si-bai-termale). If you want to know how far you are from the nearest one, from Bucharest, Cluj, Brașov, Timișoara, Oradea, Sibiu or Arad, see [the nearest thermal baths to your city](https://peplaiuri.ro/en/guides/cele-mai-apropiate-bai-termale).

## What changed at the thermal baths in 2026

**Closed.** The mofette at [Băile Seiche](https://peplaiuri.ro/en/baile-seiche), near Odorheiu Secuiesc, and the area around it have been closed since July 2026 because of gas and water leaks; the lido there has been closed since August 2017. At [Buziaș](https://peplaiuri.ro/en/buzias), the operator of the treatment centre and of the Parc, Phoenix and Timiș hotels changed owner in March 2026, and in the first half of the year the units did not take guests: check by phone before you set off.

**Reopened or under works.** At [Băile Olănești](https://peplaiuri.ro/en/baile-olanesti), the town hall's sulphur-water pool reopened in 2026 only in mid-July. At [Sângeorz-Băi](https://peplaiuri.ro/en/sangeorz-bai), the town hall is modernising the resort, with an aqua park planned, due in autumn 2026. At [Vatra Dornei](https://peplaiuri.ro/en/vatra-dornei), the baths park and the Sentinela Spring are under restoration from February 2026 to 2029, and at [Borsec](https://peplaiuri.ro/en/borsec) the spring pavilions are being restored in stages in 2025–2026; some paths and pavilions may be closed.

**Herculane.** In November 2025 a court ordered the confiscation in favour of the state of 19 buildings in [Băile Herculane](https://peplaiuri.ro/en/baile-herculane), among them the Casino and the Neptune Baths, by a ruling that is not yet final; since 2026 the resort has been part of a national pilot restoration project, running until 2030. The tubs on Via Sissi and the lidos operate separately from the historic buildings.

## Spa resorts in Moldavia and Bukovina

Moldavia has no warm thermal water on the site, but it has three old spa resorts, with mineral and salt waters, used mainly for treatment.

[Slănic-Moldova](https://peplaiuri.ro/en/slanic-moldova), the "Pearl of Moldavia", in the Nemira Mountains, 18 km from Târgu Ocna, has numbered carbonated springs you can drink from for free, on the Alley of Springs; the town hall put eleven of them back into service in 2021. Some springs are highly concentrated and are drunk only under medical supervision. Baths are taken in the treatment centres, by appointment.

[Vatra Dornei](https://peplaiuri.ro/en/vatra-dornei), in the Dorna Depression, at about 800 m, is the spa resort of Bukovina: cold carbonated and ferruginous waters, peat mud and mofettes, with a cardiovascular and rheumatological profile. Treatments are given in the hotels' centres, the largest being Bradul–Călimani, with carbonated baths and a natural mofette.

[Bălțătești Spa Resort](https://peplaiuri.ro/en/baltatesti), 12 km from Târgu Neamț, has salt, sodium chloride waters from 14 springs, used in a sanatorium of the Ministry of Defence, with treatment courses from mid-March to mid-December. It is not a bath for a day: admission is by application.

[Therme București](https://peplaiuri.ro/en/therme-bucuresti), in Balotești, on the DN1, a few kilometres north of Henri Coandă Airport, is the only thermal bath near the capital on the site. The water comes from its own borehole of about 3,100 m, from which it emerges at about 81 °C; it is treated and reaches the pools at 33–36 °C. It is not a spa resort with medical treatments but a leisure complex open all year, under a glass dome with palm trees.

It has three zones, with separate tickets: Galaxy, for families, with the wave pool and slides; The Palm, for adults, with the thermal pool and mineral-salt pools; Elysium, the sauna zone. Children under 14 have access only to Galaxy. In summer the outdoor beach opens as well.

## Mofettes: where they are in Romania

A mofette is not a water bath but a dry bath in carbon dioxide of volcanic origin: you stand in the layer of gas, with your head above it, for a few minutes, following the staff's instructions. On the site there are mofettes at [Covasna](https://peplaiuri.ro/en/covasna), where the Cardiovascular Rehabilitation Hospital has the largest built mofette in the world, of 100 m², at [Băile Tușnad](https://peplaiuri.ro/en/baile-tusnad), [Sântimbru-Băi](https://peplaiuri.ro/en/santimbru-bai), [Harghita-Băi](https://peplaiuri.ro/en/harghita-bai), [Băile Bálványos](https://peplaiuri.ro/en/statiunea-balvanyos) and [Vatra Dornei](https://peplaiuri.ro/en/vatra-dornei); the one at [Băile Seiche](https://peplaiuri.ro/en/baile-seiche) has been closed since July 2026. The gas is dangerous if you breathe it in, and the mofettes in the treatment centres are used on a doctor's recommendation. What they are, what they look like and where they all are is in the [guide to mofettes](https://peplaiuri.ro/en/guides/mofete-romania).

## Before you bathe: hours, prices and treatment

**Hours and prices.** The lidos and treatment centres set their own hours and rates, and some change from one season to another; they are on each resort's page, with the date they were checked. At many lidos you pay with the wristband you get at the entrance, and time spent beyond what you paid for is charged.

**Season.** The open-air lidos at Herculane, Geoagiu-Băi, Moneasa, Săcelu, Olănești, Homorod and Băile 1 Mai operate only in the warm season. The covered complexes or those with indoor pools (Felix, Therme, AquaPark Cozia, Wellness Tușnad, Fontana at Borsec) operate all year; the list of those open in winter is in the guide to [thermal baths open in winter](https://peplaiuri.ro/en/guides/bai-termale-iarna).

**Treatment.** All operators require a consultation with the treatment centre's doctor before procedures, because some have contraindications. The pages say what indications each resort publishes; the types of water and the treatment voucher are in the guide to [spa resorts](https://peplaiuri.ro/en/guides/statiuni-balneare-romania). At the tubs without a lifeguard at Herculane you go in at your own risk and do not stay long in the hot water, especially with heart or blood pressure problems, according to the resort's page.
