Nearest railway station is Sankrail, which is 7.5 KM away. Take Tracker car ( towards Munsirhat) from the station to reach the school. Another route is, to take bus no. 79 from Dunlop to reach Dhulagori and from there take Toto/Tracker to reach the school. After all your target should be to reach Dhulagori by any way.
