Some Rajput families fled and took refuge in the lower Himalayan region during the 17th century AD due to political instability and uncertainty. They settled in a small hamlet of Kasul by a perennial fresh water spring. With the passage of three centuries, the small hamlet by the spring has grown into a fabulous hill station of Kasauli. The hill town of Kasauli probably got its name from Kusmawali or Kusmali, a flower grown in abundance in Kasauli from spring to autumn. Some also believe that Kasuali is derived from the mountain stream Kausalaya that flows between Kasauli and Jabli.
Kasauli is visited for abundant greenery and flowers in myriad colors that looks absolutely stunning. The entire hills all around are covered with firs, horse chestnut, oaks, pines, rhododendrons and wild cherry and the ground is carpeted with green grass. During the spring season, the entire Kasauli hill stations reflects green, pink and silver colors, as dahlias, morning glory and zinnias bloom in their full glory. To add to the beauty are the number of colorful chirpy birds. Leopards, Shimla Fox, Jungle Cat and Jackal can be spotted in Kasauli.
