Immerse yourself in the unique experience of bathing in crude oil at Naftalan Oil Cure, a thermal spring in Azerbaïdjan. This sulfurous water is rich in naphthenic acids. The site is steeped in history and culture, attracting visitors from around the world, in a long thermal tradition. Come and discover this unusual spa.
Insider tip — Naftalan is one of the world's most unusual spa destinations: its baths use a rare non-combustible naphthenic crude oil which emerges at 37°C. Bathers immerse for 8-10 minutes maximum in individual cast-iron tubs filled with warm oil, emerging with a golden sheen that rinses off easily. Soviet-era sanatoriums and newer private clinics both offer this unique experience. A display of hundreds of abandoned crutches at the local museum underscores the pilgrimage nature of visits here.
