Naftalan

Naftalan is one of those destinations that needs an explanation before anyone buys a ticket. The city, located in the Aran region in the interior of Azerbaijan, exists essentially for one thing: bathing in oil. This is not a metaphor or a folkloric attraction but a real medical treatment with decades of clinical history behind it. The crude oil extracted here, known as naftalan, has an unusual chemical composition: extremely high content of cycloparaffinic naphthalenes and almost no light hydrocarbons, making it an unusually stable and non-flammable compound that Azerbaijani and Soviet doctors used to treat arthritis, psoriasis and neurological conditions.

A bath at the Naftalan sanatoriums involves immersing yourself for eight to ten minutes in a tub of crude heated to around 37 °C, always under medical supervision. The smell is exactly what you would expect: petrol station-like, dense and lingering on the skin for several hours after showering. This is not a spa experience. It is a medical procedure with an admission form, clinical history and a recommended minimum course of five to seven sessions. Visitors who come seeking relief for their joints typically stay between one and two weeks.

Outside the sanatoriums, Naftalan is a quiet city with a shaded central park, a few local product shops and a pace of life set by patients in robes strolling between treatments. For those travelling without a medical programme, one day is enough to see everything. It is not a conventional tourism destination, and that honesty is part of what makes it interesting.

The oil of Naftalan appears in European texts from the 13th century: Marco Polo, passing through the region, noted that the inhabitants used that dark oil to treat skin diseases and as an ointment for camels. The first modern sanatorium was founded in the late 19th century by the German entrepreneur Egon Hübner, who came to the Caucasus drawn by reports on the properties of the local crude. During the Soviet era, Naftalan became a treatment destination for workers from across the USSR, with dozens of sanatoriums operating simultaneously and thousands of patients a year. After Azerbaijan's independence in 1991, several centres closed or were abandoned, but the most important ones have been renovated and continue to operate with updated medical standards.

• Naphthenic oil baths The city's central experience. The heated crude tubs at 37 °C are booked directly at the sanatoriums, which require a prior medical consultation. The smell of oil is intense and lingers for hours. Duration per session: 8-10 minutes.
• Naftalan Oil Museum Small but unique: it explains the history of naftalan and displays the famous collection of crutches, walking sticks and wheelchairs left by patients who claim to have improved after treatment. Nominal entrance fee.
• Naftalan Sanatorium and Galasneft Sanatorium The two best-known and best-equipped centres. The first has renovated Soviet architecture; the second offers complete balneology programmes with packages including accommodation and transfer from Baku.
• Naftalan Central Park A tree-lined walkway in the heart of the city where patients walk between sessions on medical advice. Quiet atmosphere, no classic tourist attractions.
• Surrounding oil fields On the outskirts of Naftalan, extraction wells are visible from the road. The industrial landscape of the plain has its own documentary interest for those wishing to understand the scale of naftalan extraction.

Naftalan is about 340 km west of Baku. From Baku's Central Bus Station there are regular services to Ganja with a stop at Naftalan (5-6 hours). By car take the M1 motorway to Ganja and turn south towards Goygol; from there it is about 20 km by taxi. The Baku-Ganja train stops at Goygol. Most patients arrive with a sanatorium booking that includes an organised transfer from Baku.

The Naftalan sanatoriums operate all twelve months of the year. Spring (April-May) and autumn (September-October) are the most comfortable seasons: temperatures between 15 and 25 °C and pleasant travel across the Aran plain. Summer can exceed 35 °C in the interior of Azerbaijan, making recovery days between treatments more taxing. Winter is cold but bearable. Demand is not seasonal: it depends on each visitor's medical needs.
