Naftalan Oil Spa Azerbaijan

Naftalan in Azerbaijan offers one of the world's most singular thermal experiences — immersion bathing in naphthalan crude oil, a unique petroleum type found only in this city that has been part of local tradition since at least the 13th century when Marco Polo noted it in his travels. Naphthalan petroleum is scientifically distinct from ordinary crude oil and is enjoyed within a long bathing tradition at temperatures of 37–38°C. The Soviet-era sanatorium infrastructure has been extensively renovated into modern spa hotels, making this extraordinary petroleum bathing accessible to international wellness tourists seeking an experience genuinely unavailable anywhere else on Earth.
