If you are interested in thermal waters, therapeutic lakes, springs and caves, you have to visit Azerbaijan. You can not only relax, but also to improve your health. One of the most famous thermal springs is Istisu health-resort in Lankaran region, in Masalli. Today in Istisu there are several health-resorts, which are aimed at both budget and vip-guests. The first thing you notice upon arrival at Istisu is the smell of sulfur and steam, swirling above the ground. Therapeutic sulfuric water exits the depths of the earth, and its temperature is above 60 degrees.  The composition of natural spring – hydrogen sulfide, sodium chlorine, calcium, magnesium carbonate, and each liter of water contains 30 milligrams of iodine.  The list of diseases that are treated here is very broad: rheumatism and its side effects (arthritis, polyarthritis, joint pain), skin diseases (psoriasis, dermatitis, neurodermatitis, fungal diseases, eczema), kidney and urethra diseases, radiculitis, prostate, liver disease and biliary tract, gastrointestinal and gynecological diseases, as well as female and male infertility. The procedure is the same as in other health-resorts: first you pass the examination by a doctor, who appoints you the number of baths required for treatment. Hot water from the thermal springs flows into small individual pools or baths, in which one can stay no longer than ten minutes. Meanwhile, the water temperature is not higher than 35-40 degrees. Number of baths depends on the disease – it could be a week, or month. One more thing that makes Istisu attractive is the prices: the cost of receiving one treatment is 5-10 AZN, one day stay in the cottage – starts from 15 AZN.

Locals call this water miraculous and claim that it is the cure-all to all problems. If you are visiting in summer, you can go to the sea in Lankaran, famous for its black sand beach. It, by the way, also has healing properties. For outdoor enthusiasts there are tours to Hirkan National Park with relic plants. Unique “iron tree” is growing here and leopards were seen in the mountains. One of the most beautiful and visited places in the park is Lake Khanbulan.  Construction of cafes and restaurants is prohibited in park territory, but it is still possible to enjoy freshly brewed tea with a local jam on the lake shore, in a mobile teahouse of grandpa Ahmed. Every morning he drives to Khanbulan in his old “Zhiguli”, unloads the samovar, brews flavored Lankaran tea, lays bright colored kettles on top of the car and awaits guests. The district has a lot of sulfur thermal springs.

On the Absheron peninsula there are many methane and hydrogen sulfide mineral waters, among which the most popular are in Surakhany in the village of Zikh and waters of Shikhov Cape. These mineral waters give a high balneological effect. Masazir in the village of Masazir is an inexhaustible source of salt and valuable therapeutic mud. There are dozens of small and large lakes on the Absheron Peninsula.

Nakhichevan Autonomous Republic is rich in valuable mineral springs, which provide almost all varieties of carbonate, carbonate-chloride and hydrogen sulfide-sulfate waters.

In terms of diversity of mineral springs Nakhchivan Autonomous Republic is literally a geochemical Museum.

Five groups of springs – Darrydag, Sirab, Nagadzhir, Badamli and Gyzylvang are extremely valuable hydro-resources for balneological drinking resorts.
