Masalli Istisu, located in Azerbaijan's Masalli district near the Iranian border, is a sulfurous mineral spring whose name means 'hot mineral water' in Azerbaijani. The springs emerge in a subtropical lowland environment characterized by dense forests and tea plantations, reflecting the unique Talysh regional culture that bridges Azerbaijani and Iranian traditions. Istisu's sulfurous waters have been used within a long thermal tradition, and the site is embedded in the bathing landscape of southern Azerbaijan's border country.
Insider tip — Masalli Istisu sits in the lush Talysh lowlands of southern Azerbaijan, where the humid subtropical climate of the Caspian coast gives way to the forested Talysh mountains. The sulfurous mineral water of Istisu type at 38 °C has been enjoyed for generations and is also bottled locally. The surrounding tea plantations and dense riparian forest create a distinctly green and humid bathing environment unlike any other part of Azerbaijan. The Masalli market town is an excellent base for exploring this understated corner of the country.
