The culture of the Kalash people is unique and differs in many ways from the many contemporary Islamic ethnic groups surrounding them in northwestern part of Pakistan.
They are polytheists and nature plays a highly significant and spiritual role in their daily life. As part of their religious tradition, sacrifices are offered and festivals held to give thanks for the abundant resources of their three valleys.
Kalasha Desh (the three Kalash valleys) is made up of two distinct cultural areas, the valleys of Rumbur and Bumburet forming one, and Birir valley the other; Birir valley being the more traditional of the two.
Kalash mythology and folklore has been compared to that of ancient Greece, but they are much closer to Indo-Iranian (pre-Zoroastrian-Vedic) traditions.
The Kalash have fascinated anthropologists due to their unique culture compared to the rest in that region.
