Sopot is a Bulgarian town situated in the fertile sub-Balkan mountain valley of Karlovo (which is the western part of the famous Rose Valley), immediately below the steep southern slopes of the Troyan Balkan Mountain (Central Stara Planina). Sopot is part of Plovdiv Province and is the administrative centre of a municipality.
It lies 5 km west of Karlovo, 136 km east of Sofia, 63 km north of Plovdiv and 61 km south of Troyan. It is the birthplace of arguably the best known and most renowned Bulgarian novelist, Ivan Vazov. Sopot is also a machine building centre.
