Daridag thermal springs in the Julfa district of Nakhchivan, Azerbaijan, are known for their arsenical and oligomineral composition, emerging from a geologically complex zone where volcanic intrusions have enriched the groundwater with trace elements. Historically used in Azerbaijani folk medicine for skin and circulatory ailments, the springs reflect the broader geothermal wealth of the Nakhchivan region. Daridag's remote mountain setting, near the Iranian border, adds to its character as an undiscovered natural spa destination in the South Caucasus.
Insider tip — Daridag's thermal springs emerge in the exclave of Nakhchivan, Azerbaijan's detached southwestern territory bordering Iran and Armenia, in an area of volcanic and tectonic complexity near Aras River. The warm water at 42°C has historically served local communities for skin and joint treatments in informal rock pools. The surrounding landscape of deeply eroded volcanic hills and ancient Silk Road caravan routes provides a rich historical backdrop. The springs are rarely visited by international travelers, giving the site an almost entirely authentic local character.
