This sulfurous thermal spring is rich in naphthenic acid, a rare and distinct type of oil found only in this region. The spa's distinctive features have been part of a local tradition for centuries. Visitors can enjoy a unique bathing experience in the crude oil.
Insider tip — Naftalan is world-famous for its unique naphthalan crude-oil baths, practiced in sanatoriums here since the 13th century. Bathers immerse in shallow tubs of locally extracted naphthalan oil at body temperature for timed sessions of 8-10 minutes under supervision. This is a spa with a clinical atmosphere — bring a referral and expect a medical rather than luxury setting.
