The route, to the Dudhsagar Waterfalls, starts from Castle Rock station. Once you alight at the station, the trek is nearly 14 Kms along the railway tracks until Dudhsagar station. Since mid-July 2015, the Indian Railways has strictly prohibited walking along the railway tracks due to an incident of unruly crowd resorting to stone pelting, climbing on the Train Engine and endangering the safety of other passengers on the train at Dudhsagar Railway station. We were among the first groups arriving for the Dudhsagar trek, after the restrictions imposed by the Railways. Hence we were not quite sure what to expect when we reached Castle Rock.
