I booked MY trip from Gangtok.It took 6.5 hours to reach Lachung. <br />I stayed overnight in a Hotel and set out for Zero point and <br />Yumthang valley next day at 6 : 30 am.All Costs were included <br />in trip.Only Zero point was extra(PER PERSON RS. 200/-).After the trip toLachung expect to reach Gangtok at around 7.30 pm in the night.This is one of the best places I have visited.Truly a paradise on earth. Feels on the top of world.Chilling cold and breathtaking (hypoxic) environment.This place is worth of driving 1.5 hours from Yumthang & 3 hours from Lachung. zero point, the view of the majestic peaks of the Himalayas will make you feel that your whole <br />existence is completely insignificant.
