Kuskem waterfall! The Kuskem waterfall is located in the Canacona taluka in South Goa. It is situated in idyllic Kuskem village at about 20 km from the Cotigao wildlife sanctuary off NH 17. The waterfall at Kuskem is not very well known like the other waterfalls in Goa such as the Dudhsagar and Harvalem waterfalls. It is best visited only during the rainy season as it dries out during the summers. The water falls from a lofty source leaving a clear leap of milky water.
