Wellness Holidays: The Best Thermal Spas in Europe

Best Thermal Spas in Europe

Wellness holidays are booming. The Global Wellness Institute says that wellness tourism is one of the fastest-growing sectors, expected to increase by 21% in 2025. 

With Burnout Britain sweeping the nation, a January report from Mental Health UK suggested that 9 out of 10 UK adults had experienced extreme levels of pressure or stress in the past year. 

Wellness holidays allow the opportunity to reduce stress by focusing on mental, physical and emotional well-being, and they are expected to continue growing in popularity. Social media is also shining a new light on wellness holidays. On TikTok, videos with #wellnessretreat have over 33 million views, and on Instagram, the same hashtag has over 580,000 uses. 

Thermal spa holidays are a fantastic way to destress and treat your body to some needed rest and recovery. They are said to combat stress, help reduce anxiety and help you feel rejuvenated. With over 400 thermal spas located around Europe, there are plenty to choose from. 

With that being said, new research from Iglu Cruise has revealed the best thermal spas in Europe. The team looked into 40 of the biggest thermal spas across the continent and ranked them out of 10 for the following categories:

  • Price per day
  • Number of pools (indoor and outdoor)
  • Number of saunas and steam rooms
  • Percentage of Tripadvisor scores that were excellent (five out of five stars)

The thermal spas were then organised from 1st to 10th place for their combined rankings for each category.
