Yumthang Valley, the Valley of Flowers of Sikkim, is a soft green bowl of meadows and hot springs below snow peaks, and Zero Point is the bare, snowy spot higher up where the civilian road ends.
Both lie in North Sikkim near the border, so you need a permit, and a registered Sikkim travel agent arranges it with a registered vehicle. You base at Lachung. The flowers bloom in spring, and the snow draws crowds in winter.
Who needs a permit
You need a permit for every person, because this is a high border area. You cannot drive your own car here. You travel with a registered vehicle and a driver, and a registered agent gets the permit in your name before the trip.
The valley and Zero Point, in plain words
You stay at Lachung, a pretty town in North Sikkim, and drive up in the morning. Yumthang Valley opens out in meadows along a river, with hot springs and, in spring, sheets of rhododendron flowers. Zero Point, higher up at about 4,600 metres, is a cold, snowy end of the road with grand views. Many people add Zero Point for the snow, but it is very high and very cold, so judge it by your health.
How the permit works, in plain words
The Sikkim Tourism Department and the local administration control entry to North Sikkim. They do not sell the permit to a walk in tourist. A registered Sikkim agent applies for you, with your identity and photos, and gets the permit before you go. That is why you plan this through an agent or a tour, staying at Lachung the night before.
For foreign visitors
Foreign visitors can usually see Yumthang Valley with a Protected Area Permit, arranged by a registered agent, travelling in a small group. Zero Point is often restricted for foreigners, and the rule can change, so ask a registered agent before you count on it. Carry your passport, and give the agent extra time for a foreigner permit. [Confirm the current foreigner rule with a registered agent. Last checked 13 September 2026.]
Altitude care
Zero Point is high, at about 4,600 metres, so the air is thin and cold. Spend the night at Lachung first, move slowly at the top, and stay only a short time. If you feel a bad headache, sickness or breathlessness, come down. People with heart or lung trouble should take medical advice before adding Zero Point.
How to arrange it, step by step
Pick a registered Sikkim agent or a North Sikkim tour that includes Lachung, Yumthang and, if you wish, Zero Point. Give your identity, passport size photos and dates ahead of time. Stay the night at Lachung. Start early with the registered vehicle. Carry the same original identity, because it is checked at the check posts.
Season, so you plan the right months
Yumthang is loveliest for flowers from about March to May, when the rhododendrons bloom. Winter brings snow and big crowds for Zero Point. The monsoon can block the road with landslides, so avoid the heavy rain months. Even in summer it is cold up high, so carry warm layers.
Common mistakes to avoid
- The biggest mistake is planning Zero Point without thinking about the height and cold. Foreign visitors often assume Zero Point is open to them, when it is often restricted. Do not try to go without a registered agent and permit. Do not visit in the heavy monsoon, when landslides block the road.
