Trekking in Dudhsagar is a famous tourist attraction. There are two abandoned shelters for the refuge of trekkers (left to the falls and right side beside the railway track). They are available on first-come-first-served basis. Medical and pure drinking water facilities are not available around Dudhsagar but one can approach the station master at Dudhsagar Falls railway station in emergency. There are 4 possible trek routes to reach Dudhsagar Falls, of which only two are accessible in monsoon.
Route 1 (Castle Rock Route)
This is the most famous route during the monsoon. Reach Castle Rock station and start a Scenic 14 km hike to Dudhsagar Water falls along the railway track. It normally takes 5–6 hours to reach. The route passes through a number of railway tunnels, a board reading "Welcome to Goa" and offers a great view of the Valley. One has to be careful of trains while walking along the railway track.
Route 2 (Kulem Route)
This is equally scenic but less popular as compared to Route 1. One has to get down at Kulem (Collem) railway station(Station Code: QLM) and walk towards the falls which is about 11 km away. It normally takes 4–5 hours to reach. The famous photograph of Trains passing through before the waterfalls can be seen in this route and also the complete stretch of the falls is visible while hiking towards the waterfalls.
Route 3 (Transport + Hike)
In Kulhem one can hire a 4X4 SUV to reach the foot of Dudhsagar waterfalls. There is a taxi stand called 'Dudhsagar Taxi stand' where one can hire a vehicle and get down near the falls which is just 1 km hike away. This is suitable for large groups with kids, but it cannot be used during monsoon season.
Route 4 (Kuveshi-Dudhsagar)
This is the most adventurous route and cannot be attempted in monsoon since one has to cross Mondovi river during the hike. The hike starts from a village called Kuveshi around 10 km from Castle Rock railway station. The hike is through thick jungle and is difficult to complete without experience. By this route, one can reach Dudhsagar Railway station which is 1 km from the falls.
