ADRIATIC ISLANDS: 5 Lesser-Known Oases for a Dream Vacation
December 8, 2025The highest concentration of Croatia’s thermal springs, bathing complexes and health resorts is found in the continental part of the country: Hrvatsko Zagorje, Međimurje, Slavonia, central Croatia and Istria. In this guide, we compare the best-known thermal spas and resorts, explain who they suit, what to check before travelling, how to find a more affordable option and which spas are most convenient from Zagreb.
The terms thermal spa, thermal resort, thermal bathing complex, spa and wellness are often used interchangeably, but they do not always mean the same thing. Thermal spas and resorts are usually connected to a natural thermal or mineral spring, while a spa and wellness centre can operate without thermal water.
Quick answer: which thermal spa should you choose?
- Best all-round choice: Terme Tuhelj, thanks to its combination of pools, saunas, wellness facilities and family-friendly attractions.
- For children and water attractions: Terme Jezerčica, Terme Tuhelj, Aquae Vivae and Bizovačke Toplice.
- For couples and a quieter wellness break: Terme Sveti Martin and Terme Tuhelj.
- For rehabilitation: Daruvarske Toplice, Naftalan, Stubičke Toplice and Varaždinske Toplice, depending on the medical indication and programme availability.
- Near Zagreb: Terme Tuhelj, Terme Jezerčica, Krapinske Toplice, Stubičke Toplice and Naftalan.
- For a more affordable day visit: compare weekday admission, shorter time slots and family tickets rather than hotel wellness packages.
Why thermal spas matter
Croatian thermal spas combine three different reasons for travelling: relaxation, water-based fun and health programmes. That is precisely why it makes little sense to assess every complex using the same criteria. A family with young children will value shallow pools and waterslides, couples will look for saunas and treatments, while anyone needing rehabilitation must first check the institution’s medical specialisation.
Thermal water and health resorts
Natural thermal or thermomineral water is used in bathing, recreational and medical programmes. Its medical effect depends on the composition of the water, the diagnosis and a professionally supervised programme.
Year-round breaks
Indoor pools, saunas and wellness facilities make thermal spas worthwhile even when the weather is unsuitable for the seaside, excursions or outdoor activities.
A weekend without complicated logistics
Most of the best-known thermal spas are within a reasonable distance of Zagreb, Varaždin, Čakovec, Osijek and other continental cities.
Combine your visit with local excursions
Zagorje, Međimurje, Daruvar and Istria allow you to combine swimming with castles, wine routes, gastronomy, walks and cultural attractions.
Important: this guide is intended for travel planning and comparing available options. It is not a substitute for medical advice. Before undertaking rehabilitation, therapy or using exceptionally hot water, consult your doctor and the institution you plan to visit.
Thermal spas in Croatia: map and list by region
The easiest approach is to choose a region first and then decide which facilities you need. The following overview serves as a practical map of Croatia’s thermal spas, showing where the greatest concentration is located and highlighting the main destinations in each part of the country.
Hrvatsko Zagorje
Aquae Vivae, Terme Tuhelj, Terme Jezerčica and Stubičke Toplice. The most convenient region for a day trip or weekend break from Zagreb.
Međimurje and northern Croatia
Terme Sveti Martin and Varaždinske Toplice. A good choice for wellness, active holidays, history and health programmes.
Slavonia and western Slavonia
Bizovačke Toplice and Daruvarske Toplice. Bizovac is better suited to water-based fun, while Daruvar focuses more on rehabilitation and quieter health breaks.
Istria and central Croatia
Istarske Toplice, Topusko and Naftalan in Ivanić-Grad. The offer is varied, ranging from sulphurous water and wellness to specialised rehabilitation.
For broader travel planning, see our Croatia guide. For ideas you can combine with a thermal weekend, open our guide to excursions and activities in Croatia.
The best thermal spas in Croatia by type of holiday
There is no single, objectively best option for everyone. It is more useful to choose according to the real purpose of your trip.
| What you are looking for | Recommended choices | Why |
|---|---|---|
| A family day with children | Jezerčica, Tuhelj, Aquae Vivae, Bizovac | Several pools, children’s zones, water attractions and enough facilities for a full-day visit. |
| A wellness weekend for two | Sveti Martin, Tuhelj | A more extensive selection of spa facilities and saunas, as well as more activities beyond swimming. |
| Rehabilitation and health programmes | Daruvar, Naftalan, Stubičke, Varaždinske | Specialised institutions and medical programmes; your choice should follow your diagnosis and doctor’s recommendation. |
| The shortest excursion from Zagreb | Jezerčica, Tuhelj, Krapinske, Stubičke, Naftalan | A relatively short drive and enough facilities for half a day or a full day. |
| Thermal spas combined with regional sightseeing | Zagorje, Međimurje, Daruvar, Istria | Easy to combine with castles, wine, gastronomy and walks. |
Thermal spas in Hrvatsko Zagorje
Hrvatsko Zagorje has the highest concentration and most varied selection of thermal spas in the country. Within a relatively small area, you can choose between a large water park, a family-oriented thermal hotel, a fully developed wellness resort and a specialist rehabilitation hospital.
Aquae Vivae – Krapinske Toplice
Krapinske Toplice has a long tradition of using thermomineral water, while Aquae Vivae today primarily operates as a modern water park. It is a good choice when you want to combine thermal water, recreational swimming, family-friendly facilities and wellness without booking a hotel package.
The complex includes indoor and outdoor pools, a wave pool, children’s facilities, a waterslide, wellness facilities and a diving pool. This broad range makes it one of the more practical answers to searches such as “thermal spas for children” and “pools near Zagreb”.
Terme Jezerčica – Donja Stubica
Terme Jezerčica is located in Donja Stubica and combines a family water park with a smaller wellness break particularly well. Its official facilities include eight pools with natural thermal water, an indoor section open throughout the year and an outdoor water park operating during the warmer months.
Jezerčica is particularly convenient if you are travelling with children but do not want a large, logistically demanding resort. Oršić Castle, the Museum of Peasant Uprisings and other Zagorje attractions are nearby, making it easy to turn your swim into a full-day excursion.
Stubičke Toplice
Stubičke Toplice is not the same type of destination as Jezerčica or Aquae Vivae. Its main identity is connected to the Specialist Hospital for Medical Rehabilitation, thermal water, physical medicine and medical wellness.
Updated in July 2026: the large pool has been closed since 18 May 2026 until further notice. The wellness centre, spa zone and hydromassage pool may operate according to a separate timetable, so check the official notice and current opening hours before travelling.
Choose this location when peace, a therapeutic approach and a professionally supervised programme matter more to you than waterslides and full-day water-based entertainment.
Terme Tuhelj – Tuheljske Toplice
Terme Tuhelj is the most balanced choice when members of the same group have different needs. Children have water attractions and pools, adults have saunas and wellness facilities, and everyone has enough to do for a full-day or weekend stay.
Water Planet extends across a large indoor and outdoor area, while thermal water and healing mud form part of the identity of Tuheljske Toplice. Compared with smaller complexes, Tuhelj operates more like a complete resort, so it makes sense to choose it when you want to stay for one or two nights.
To explore the region alongside your swim, combine Tuhelj with an excursion to the castles of Zagorje. You can find ideas in our guide to castles in Croatia.
Thermal spas in Slavonia and Međimurje
Bizovačke Toplice – Bizovac
Bizovačke Toplice is one of the strongest choices in eastern Croatia. Aquapolis combines indoor pools that operate throughout the year with a large outdoor section during the summer season, so the destination works well both as a family bathing complex and a short wellness break.
Official sources particularly emphasise its hypersaline, iodine-rich thermal water. For the average visitor, the more practical question is whether you want a quieter indoor visit or a summer day with waves, children’s facilities and a larger outdoor area.
Daruvarske Toplice – Daruvar
Daruvarske Toplice has a clearer health-oriented profile than most conventional thermal resorts. Its focus is on physical medicine, the musculoskeletal system, rehabilitation and programmes using thermal water and mineral mud.
That does not mean it is intended only for patients. Daruvar is pleasant for a quieter wellness weekend, walks through Julijev Park and a combination of swimming, gastronomy and local heritage. Nevertheless, when choosing a rehabilitation programme, the medical indication and professional plan matter more than the package’s marketing name.
Terme Sveti Martin – Međimurje
Terme Sveti Martin stands out most for its combination of thermomineral water, wellness, active holidays and Međimurje gastronomy. Compared with a traditional bathing complex, the emphasis here is more on a complete resort stay.
This makes it a good choice for couples and guests who do not want to spend the entire day beside the pool. Cycling, wine routes, local cuisine and peaceful countryside provide enough activities for a long weekend.
Thermal spas in Istria and central Croatia
Istarske Toplice – Livade
Istarske Toplice is set in a different environment from most continental thermal resorts: beneath the tall Gorostas cliff, in the green Mirna River valley. Its natural sulphurous water is used in bathing, wellness and rehabilitation programmes.
Its greatest advantage is not a large water park, but the combination of a quieter stay, natural surroundings and proximity to inland Istria. A visit is easily combined with Motovun, Grožnjan, Buzet and a gastronomic excursion.
Top-Terme Topusko
Topusko has a long history of thermal treatment and an important role in rehabilitation. However, its offer should be assessed according to the current condition of its facilities rather than outdated descriptions of its pools and hotels.
Updated in July 2026: the official website lists closures of some pool facilities related to the renovation of the hotel complex. Before travelling, check whether the indoor and outdoor pools are operating and which programmes are currently available.
Varaždinske Toplice – Minerva and Aquae Iasae
Varaždinske Toplice is one of Croatia’s most important historic thermal locations. The Roman settlement of Aquae Iasae developed on the site of the present-day town, and its remains give this destination value beyond bathing alone.
Important current information: the Minerva accommodation facility and its indoor and outdoor pools are closed for reconstruction. The work is in its final phase during 2026, but always check for official confirmation of reopening before planning to swim or stay overnight.
Articles about Varaždinske Toplice often continue to present its former facilities as though they were operating normally. That is currently inaccurate and can disrupt a visitor’s entire travel plan.
Naftalan – Ivanić-Grad
Naftalan is located in Ivanić-Grad, not in Krapinske Toplice. This is an important correction because older guides often incorrectly place it in Zagorje.
Naftalan Specialist Hospital is known for treatments using the natural mineral oil naftalan, thermomineral water and programmes for skin and rheumatic conditions. For travellers looking for a medical wellness programme or rehabilitation, it is a more relevant choice than a conventional family water park.
Thermal spas for children, couples and rehabilitation
The best thermal spas for children
Jezerčica, Tuhelj, Aquae Vivae and Bizovac have the clearest family-oriented profile. Check age restrictions for waterslides, pool depths and whether the outdoor area is operating during your visit.
Thermal spas for couples
Sveti Martin and Tuhelj offer more facilities for a weekend for two, including saunas, treatments, wellness zones and a better range of activities beyond the pools.
Thermal spas for rehabilitation
Daruvar, Naftalan, Stubičke and Varaždinske Toplice have a stronger medical profile. Do not choose an institution based only on distance, but on its specialisation and your doctor’s recommendation.
Thermal spas for older visitors
The most important considerations are accessibility, quieter time slots, lifts, pool depth, access to doctors and packages including therapies or full board.
How does thermal spa treatment through HZZO work?
Attending a thermal spa through HZZO is not the same as buying a wellness package. Inpatient medical rehabilitation is granted on the basis of a medical indication, referral and the rules of compulsory health insurance, and is provided in contracted healthcare institutions.
Practical advice: first speak to your family doctor or the specialist supervising your treatment. The institution, duration and form of rehabilitation are not selected solely according to personal preference or the tourist offer.
Thermal spas in Croatia: admission prices and the real cost of a visit
Prices vary according to the day of the week, season, length of admission, the child’s age and whether the ticket includes saunas or pools only. For this reason, a single fixed price for “thermal spas in Croatia” is not useful. It is better to compare specific examples and check the official price list immediately before purchasing.
| Example | Verified price | What you need to know |
|---|---|---|
| Aquae Vivae | Full-day adult admission €18; child admission €12; three-hour adult admission €14 | Family tickets are also available; the official price list was checked in July 2026. |
| Bizovačke Toplice | Adult day admission from €10 on weekdays and €11.50 at weekends | Prices and outdoor-area availability depend on the season; checked against the official price list in July 2026. |
| Stubičke Toplice | Spa zone €15; combined spa-zone and pool admission €18 according to the published price list | The large pool is currently closed, so check exactly what the package includes before purchasing. |
In addition to admission, allow for a towel or bathrobe rental, locker, food, massage, sauna, parking and possible accommodation. A family ticket is often better value for families, while couples should compare a day spa package with a one-night stay including wellness facilities.
Affordable thermal spas in Croatia and money-saving tips
An “affordable thermal spa” is not necessarily the one with the lowest starting price. The better-value option is the one that provides enough facilities without additional charges or an unnecessary overnight stay.
- Visit on a weekday. Admission is often cheaper, while pools and saunas are quieter.
- Check shorter admission options. If three or four hours are enough, there is no reason to pay for a full day.
- Compare family tickets. For two adults and children, these may be considerably cheaper than individual admission.
- Do not buy a package containing services you will not use. Saunas, massages and lunch can increase the price by more than the admission itself.
- Look for accommodation outside the hotel complex. A private apartment or holiday home nearby often provides more space and flexibility.
- Check the current availability of facilities. A discount is not a saving if the main pool is closed or the outdoor area is not operating.
The smartest comparison: add up admission, fuel, food and any overnight accommodation. Only then can you see whether a more distant “cheaper” option is genuinely better value.
Thermal spas near Zagreb
For a day trip from Zagreb, the thermal spas in Zagorje and Ivanić-Grad are the most convenient. The differences in distance are small, so the facilities matter more than a few extra kilometres.
| Thermal spa | Approximate distance from Zagreb | Best for |
|---|---|---|
| Terme Jezerčica | around 40 km | Families and day trips |
| Terme Tuhelj | around 50–55 km | Full-day visits and wellness weekends |
| Aquae Vivae | around 50 km | Water parks and family swimming |
| Stubičke Toplice | around 40 km | Medical wellness programmes, subject to checking pool availability |
| Naftalan, Ivanić-Grad | around 45 km | Medical programmes and rehabilitation |
Are there thermal spas in Dalmatia and on the coast?
When travellers search for “thermal spas in Dalmatia”, they are often actually looking for a hotel with a spa centre, heated pool or seaside wellness facilities. This is not the same as a traditional continental thermal spa built around a natural thermal spring.
Dalmatia has a well-developed hotel wellness offer, but it does not have a concentration of large, traditional thermal bathing complexes comparable to Zagorje, Međimurje or Slavonia. If natural thermal water is your main priority, focus on the continental regions. If you want spa facilities, massages, saunas and a heated pool by the sea, search for accommodation with wellness facilities rather than necessarily looking for a “thermal spa”.
For a broader choice of coastal activities, see our guide to what to do in Croatia and our overview of water parks in Croatia.
Thermal spas outside Croatia: Slovenia and Bosnia and Herzegovina
If distance is not a concern, it is worth including a regional comparison, although it should not take over the main theme of an article about Croatia.
- Terme Olimia, Slovenia: a strong wellness and family-oriented offer.
- Terme Čatež, Slovenia: a very large water complex with camping facilities.
- Rogaška Slatina, Slovenia: a pronounced health and mineral-water identity.
- Laško, Slovenia: a combination of thermal facilities, wellness and a town excursion.
- Reumal Fojnica, Bosnia and Herzegovina: focused on rehabilitation and health-resort treatment.
- Banja Vrućica, Bosnia and Herzegovina: a larger health and tourism complex.
For travellers from Croatia, it makes sense to compare the total driving distance, vignettes or tolls, accommodation and package prices first. Cheaper admission in another country does not necessarily mean a cheaper excursion.
Tips for visiting thermal spas
- Check the current status immediately before travelling. Renovations, seasonal opening and technical maintenance may close some pools.
- Book treatments in advance. Massages and saunas have lower capacity than pools.
- Bring swimwear, slippers and a towel. Check whether bathrobe or towel hire is charged separately.
- Drink enough water. Warm water and saunas increase the risk of dehydration.
- Follow the recommended bathing duration. This is particularly important with very warm water and health conditions.
- Check the rules for children. Not all pools and wellness areas are available to every age group.
- Do not confuse rehabilitation with wellness. A medical programme requires professional assessment, while a tourist spa package is a recreational service.
FAQ – Thermal spas in Croatia
Which are the best thermal spas in Croatia?
For a comprehensive selection of facilities, Terme Tuhelj, Terme Jezerčica, Aquae Vivae, Terme Sveti Martin, Bizovačke Toplice and Daruvarske Toplice are among the most notable. The best choice, however, depends on whether you are looking for a family water park, wellness facilities or rehabilitation.
Which are the best thermal spas in Croatia for children?
Terme Jezerčica, Terme Tuhelj, Aquae Vivae and Bizovačke Toplice are the most convenient for children because of their larger number of pools and water attractions. Before arriving, check whether the outdoor section is open and whether age or height restrictions apply.
Which thermal spas are best for rehabilitation?
Daruvarske Toplice, Naftalan, Stubičke Toplice and Varaždinske Toplice have strong medical and rehabilitation profiles. Your choice should be based on your diagnosis, the institution’s specialisation and your doctor’s recommendation, rather than the popularity of the spa alone.
Which thermal spas are closest to Zagreb?
The most convenient options include Terme Jezerčica, Stubičke Toplice, Aquae Vivae, Terme Tuhelj and Naftalan in Ivanić-Grad. Most are approximately 40 to 55 km from Zagreb.
How much do thermal spas in Croatia cost?
Day admission prices depend on the complex, season and day of the week. In current official examples, basic adult day admission ranges from approximately €10 to €18, while saunas, wellness facilities, massages and family packages affect the total price.
Which are the cheapest thermal spas in Croatia?
The best-value option depends on the date and group size. Weekday visits, shorter admission or family tickets are usually the most economical. Compare travel costs as well, because a more distant spa with cheaper admission may ultimately cost more.
Are there thermal spas in Dalmatia?
Dalmatia has many hotels with spa and wellness facilities, but it does not have the same concentration of large traditional thermal spas as Zagorje, Međimurje and Slavonia. For natural thermal water, continental Croatia is the more practical choice.
Can I receive thermal spa treatment through HZZO?
Inpatient medical rehabilitation may be obtained according to a medical indication, referral and HZZO rules at contracted institutions. A tourist wellness package and rehabilitation through HZZO are not the same service.
Are Varaždinske Toplice currently open?
The town and the Roman archaeological site of Aquae Iasae can be visited, but the Minerva facility and its indoor and outdoor pools are closed during reconstruction. Check the official reopening announcement before travelling.
What is the difference between thermal spas, thermal resorts and spa and wellness centres?
Thermal spas and resorts are usually connected to a natural thermal or mineral spring. Spa and wellness centres offer relaxation facilities, saunas, treatments and pools, but they do not necessarily use natural thermal water.
