St. Clair's waterfall is located along the Kotmale Oya, a tributary of the Mahaweli River, as it cascades over three rock outcrops into a large pool while passing through a tea estate, which gives the falls their name. The waterfalls are made up of two falls: "Maha Ella" (Sinhalese for "The Greater Fall"), which is 80 m (260 ft) high and 50 m (160 ft) wide, and "Kuda Ella," which is 50 m (160 ft) high and located immediately downstream of the main fall.

Anyone traveling to Nuwara Eliya via the Hatton-Thalawakele route may come across this mind-blowing waterfall. It lies 500 m away from the main route after passing Hatton, which offers an incredible view of a range of mountains and valleys.
