Measuring a mighty 600m from head to foot, the famous waterfalls at DUDHSAGAR , on the Goa-Karnataka border, are some of the highest in India, and a spectacular enough sight to entice a steady stream of visitors from the coast into the rugged Western Ghats. After pouring across the Deccan plateau, the headwaters of the Mandovi River form a foaming torrent that fans into three streams, then cascades down a near-vertical cliff face into a deep green pool. The Konkani name for the falls, which literally translated means "sea of milk", derives from clouds of foam kicked up at the bottom when the water levels are at their highest. Overlooking a steep, crescent-shaped head of a valley carpeted with pristine tropical forest, Dudhsagar is set amid breathtaking scenery that is only accessible on foot or by Jeep; the old Vasco-Castle Rock railway actually passes over the falls on an old stone viaduct, but services along it are infrequent.
