The Municipality of Polihnitos Lesvos is the result of joining the exquisite villages and settlements of Vassilika, Lisvori, Polichnitos, Skala Polichnitou, Nifida, Vrissa, Vatera and Stavros. These areas combine landscapes of exceptional natural beauty marked by the presence of man since ancient times. The Municipality of Polichnitos is located in the south-western part of the island (45 km from the island capital, Mitilini) plumed by olive groves, pinewoods, water springs and fabulous beaches. The name Polichnitos is a compound of the Greek words for many traces and according to a folk tale, numerous very small villages, primarily located on the coast, was forced to move to their present location away from the sea in fear of Saracen pirates. Their current location is surrounded by barrows and is therefore out of sight for anyone approaching the Kalloni bay and the Aegean Sea. This location is known for the Palaeolithic tools discovered here and the systematic record and study of animal fossils in the area of Vatera. Visitors can tour countless Pale Christian churches, monasteries, picturesque country tabernacles and marvel at the unique stone structures of present day settlements, the Folk Museum, the Museum of Natural History, the thermal baths of Polichnitos and Lisvori and the Kalloni bay and Almiropotamos reserves. All these sites are combined with the vastitude of the Vatera and Nifida beaches, cosy accommodations in local hotel complexes and fresh fish and shellfish picked up from the bay, ouzo and coffee, which visitors can enjoy in the numerous shops located on the beach.Polichnitos Thermal baths.
The detour to the thermal bath establishment is on the road leading from Polichnitos Lesvos to Vatera. Spa waters spout from numerous springs passing through primary and secondary volcanic porous rock. Water temperatures range between 67°C and 92°C (bath temperatures range between 42°C and 44°C) in baths enriched with natural radon irradiation in the range of 15 - 25 MACHE units and is considered to be of the warmest springs in Europe. 
They are rich in sodium chloride and comparable to the Wiesbaden springs in Germany. The baths and pools are housed in a series of low constructions on the right, built under tall eucalyptus trees. These are the old buildings, which have been operating for numerous years that were renovated to fit modern needs and include both old and new water channels. The water springs free and steaming hot, and as a result of thermopile animalcules (algae) growing in it, on its way down gives the floor a beautiful red colour.A little further out behind the sedge woods is another building complex that houses the oblong dormitories and vaulted old spa. The three arched bridge of Almiropotamos is yet another sight to see in the area, and one of the last ones still standing today, as is the old spring made of yellow and pink soft-stone. The Polichnitos Lesvos thermal baths have been in use since the Turkish domination and have been operating with two pools since 1959. The water is clear and odourless enriched with carbonic acid, chloride and sulphate, sodium and calcium salts, free carbon dioxide, iron, magnesium and manganese compounds, as well as oxygen and traces of iodine and bromium. 
In addition to the baths relaxing properties, they are also helpful in: chronic rheumatism, arthropathies (chronic degenerative and deforming disorders), radix neuritis, chronic disk arthritis, lumbago, sciatica, skeletal deformities or post traumatic injuries, secondary skin disease, gout, peripheral vasopathies, extra pulmonary tuberculosis, chronic upper respiratory inflammatory diseases, gynaecological inflammatory diseases, fallopian tube dysfunction - dysmenorrhoeal, female sterility and gastritis, particularly indigestion, underdeveloped flora accompanied by hypo tonicity and gastric lassitude. On the way to Lisvori and through an olive grove is the road to the local springs. 
A rivulet with wicker trees growing in the mud marks the place of the hot water bubbling spring surrounded by a man made wall. The radon irradiation rich water reaches temperatures of 69º C. This water is also rich in sodium chloride and of similar composition and indications as the Polichnitos hot water springs. This spa is equipped with two pools, one of which was built during the Turkish domination times. A renovated 20 bed hostel and small café also operate in the Lisvori spa, next to the Saint John (Agios Ioannis) tabernacle.
