Naftalan: Azerbaijan's medicinal crude-oil spa town

People come to Naftalan for a treatment available in only two places on earth: a bath in warm brown crude oil, taken as a medical treatment rather than a stunt. Azerbaijan and Ivanić-Grad, Croatia, are the only places that offer it, and Naftalan is the original and larger of the two. The town has built its whole identity and its hotels around the local oil, and a stop here is as much about the sanatorium culture as the bath itself. Here is what the oil actually is, what a treatment involves, and how to fit Naftalan into a trip through western Azerbaijan.

What is Naftalan?

Naftalan is a small city in western Azerbaijan, set in the lowlands not far from Ganja, that grew up around a distinctive grade of medicinal crude oil. Roughly half of that oil is made up of naphthenic hydrocarbons, the cycloalkane fraction the sanatoriums prize, which is what sets it apart from ordinary fuel crude. The town is essentially a cluster of treatment hotels, and the oil has drawn patients for well over a century, with a Soviet-era peak of around 75,000 visitors a year.

What is Naftalan oil, and is it the same as naphthalene?

It is not the same thing, and the confusion is worth clearing up. Naftalan oil is a naphthenic crude oil whose medicinal value comes from its naphthenic hydrocarbon content. Naphthalene, by contrast, is the white crystalline solid used in mothballs. The names sound alike and many popular articles run them together, but they are different substances. The spas at Naftalan use the heated crude oil, not naphthalene.

What happens during a Naftalan oil treatment?

You sit in a tub of the warm brown oil, usually immersed up to the neck, for about ten minutes, after which the oil is scraped and washed off. The oil is heated to a little above body temperature, in the region of 38 to 39 °C. Treatment is done under sanatorium supervision and normally starts with a doctor's screening, since the oil is not recommended for everyone. Hotels also offer paraffin wraps and other oil-based therapies alongside the baths. The reputed benefits, often cited for joint, skin and musculoskeletal complaints, are claimed rather than clinically proven, so treat them as traditional therapy taken under medical care.

What else is there to see in Naftalan?

The local curiosity beyond the baths is the museum of crutches, a display of walking aids reportedly left behind by patients who arrived needing them and departed without. It captures the town's self-image neatly. The oil's reputation is old: it was referenced by the 12th-century poet Nizami and, by some accounts, reached Marco Polo. Otherwise Naftalan is a quiet sanatorium town rather than a sightseeing city, which is why most travelers pair it with Ganja, the regional hub an hour away.

How do you get to Naftalan, and how does it fit a trip?

Naftalan is about 330 km from Baku, a drive of roughly 3.5 to 4.5 hours, but only around an hour from Ganja, so almost everyone reaches it through Ganja rather than straight from the capital. That makes it a natural western-Azerbaijan add-on. On our 6-day Azerbaijan cultural tour it sits on the run between Sheki and Ganja, where an overnight lets you take a bath properly rather than rushing one in. A pure day visit is enough to see the town and the museum, but the oil treatments are designed as a multi-day course, so a stay suits them better.

When should you go?

Any time of year works, because the treatments are indoor and the sanatoriums run year-round. The surrounding lowlands are hot in midsummer and cool in winter, so spring and autumn are the most comfortable for moving around outside, but the bath schedule does not depend on the season. If you are coming specifically for a course of baths, plan several days; if Naftalan is one stop on a wider western loop, a night is plenty.
