Dudhsagar Falls (literally Sea of Milk ) is a four-tiered waterfall located on the Mandovi River in the border of the Indian state of Goaand Karnataka. It is 60‚ km from Panaji by road and is located on the Madgaon-Belgaum rail route about 46‚ km east of Madgaon and 80‚ km south of Belgaum. Dudhsagar Falls is amongst India’s tallest waterfalls with a height of 310 m (1017‚ feet) and an average width of 30 metres (100‚ feet).

The falls is located in the Bhagwan Mahaveer Sanctuary and Mollem National Park among the Western Ghats. The waterfall forms the border between Karnataka and Goa states. The area is surrounded by a deciduous forests with a rich biodiversity. The falls are not particularly spectacular during the dry season but during the monsoon season however, the falls are fed by rains and form a huge force of water.

The river Mandovi, which is the main river of Goa, begins on the Deccan plateau in the state of Karnataka. Winding its way through the Western Ghats, this river plummets over the highest peaks on the border of Goa and Karnataka, thus forming the Dudhsagar falls. The waters form a deep green pool at the base of the falls, before continuing westward to join the Arabian Sea.

The nearest rail station accessible by road to the falls is Castle Rock station. Visitors could get in a train from here and disembark at the Dudhsagar stop. It is to be noted that the Dudhsagar rail stop is not a station where passengers can expect a platform. Passengers and visitors have to climb down the steep ladder of the rail compartment in a short 1-2 minute unscheduled stop. From this rail stop, visitors have to walk about a kilometer on the tracks to arrive at the falls. While the walk itself is something unexpected for a popular tourist destination, there is a 200 m train tunnel that is totally dark which makes the walk a bit tougher. Recently Indian Railways has banned people from boarding/deboarding passengers at Dudhsagar railway.‚ There is no availability of fresh drinking water nor clean rest room facilities anywhere in the vicinity of the falls including at the rail stop. There is absolutely no access to power or cellular signal at this location just as there is no access to road transportation.
