Avoid this place till the roads are repaired. The current detour is 55km longer with narrow and treacherous roads. It took 9 hours each way to cover 175 km. We were lucky. Others have taken 12-14 hours after getting stuck in traffic jams. Also, i strongly recommend staying here for 2 nights to really enjoy lachung. Travel agents recommend 1 night. But that's just very tiring. The trip from lachung to yumthang and zero point is 6 hours itself. And at that height it takes time to acclimatize. Even walking 10 steps will leave you breathless.

From Lachung to Zero point is a good ride as it is scenic and you are literally on top of the world ; 16,000 feet !! Well managed by the army but can get crowded so leave early and reach early. Easy to rent boots / gloves and jackets on the way. You will almost see where Teesta river originates. Zero point itself will not get crowded but cars and pollution of Diesel vehicles can bother if you reach at peak time with most people. So best is to reach early.

Yume Samdong, also known as Zero Point, is a mesmerizing snow-covered valley located in North Sikkim, India, approximately 26 kilometers northeast of Yumthang Valley and accessible only with a special permit. Here's a more detailed look at Yume Samdong: Location: Situated along the Lachung River, Yume Samdong is 20 kilometers beyond Yumthang Valley. Accessibility: A special permit is required for entry, and only domestic/Indian tourists are allowed. It's a 2-hour drive from Lachung to Zero Point.

Zero point Sikkim stands at an altitude of 15,300 feet above mean sea level and is the last outpost of civilization. The road ends here!!! I have visited with 9 year old daughter and 70 years aged parents without any problems. Also witnessed snow fall .The drive from Yumthang Valley to Zero Point is through the curving mountainous amidst the rugged piece of land of geographic region and could be a lifetime experience. (Like Tawang and Ladakh)

This is a real paradise on the earth. And a must visit. Rented gum boots from a shop near to yumtang valley, this gives a good grip, when you venture out to snow. Luckily we experienced a light snow fall. Breath taking views of the mountains around. Maggi and hot tea there. Perfect place to get away from usual city chores.
