The Rose Valley (Bulgarian: Розова долина, romanized: Rozova dolina) is a region in Bulgaria located just south of the Balkan Mountains and the eastern part of the lower Sredna Gora chain to the south. Geologically, it consists of two river valleys, those of the Stryama to the west and the Tundzha to the east.
The Rose Valley of Kazanlak stretches for 10-12 kilometers and is 95 kilometers long with an average height of 350 meters and an area of 1895 square kilometers.
The valley is famous for its rose-growing industry which have been cultivated there for centuries, and which produces close to half (1.7 tonnes) of the world's rose oil. The centre of the rose oil industry is Kazanlak, while other towns of importance include Karlovo, Sopot, Kalofer and Pavel banya. Each year, festivals are held celebrating roses and rose oil.
The picking season lasts from May to June. During this period, the area gives off a pleasant scent and is covered with multi-coloured flowers. The gathering process, traditionally a woman's task, requires great dexterity and patience. The flowers are carefully cut one by one and laid in willow-baskets which are then sent to the distilleries. Tourists are welcome to join the rose-picking process, usually on weekend mornings when special ritual reenactments are organized in villages around Kazanlak.
