Insider tip — Hisarya is a celebrated Bulgarian spa town with Roman-era thermal baths enclosed within preserved 3rd-century AD fortress walls — making it one of Europe's most historically layered balneological destinations. The bicarbonate waters emerge at a steady 37-52 degrees and have been recommended for digestive and urological conditions since antiquity. Walking the Roman mineral spring circuit between park-set fountains is a unique cultural-thermal experience.
