Do I need a permit to visit North Sikkim?
Yes. Indian citizens need an Inner Line Permit (ILP) to enter Lachen, Lachung, Gurudongmar, Yumthang and Zero Point. Foreign nationals need a Protected Area Permit (PAP) processed through a registered Sikkim-based travel agency. We are registered with the Sikkim Tourism Department (number 601/DoT&CAv/GTK/21/TA) and process both permits ourselves — no sub-contracting.
How many days do I actually need for North Sikkim?
A minimum of 3 nights and 4 days to see both Gurudongmar (from Lachen) and Yumthang Valley + Zero Point (from Lachung). The often-advertised 2 nights / 3 days only covers Lachen and Gurudongmar — Lachung does not fit into that window. If you also want Dzongu (Lepcha cultural area), plan for 4 nights and 5 days.
Is Gurudongmar Lake safe at 5,430 m?
For most healthy adults, yes — we have run more than 12,000 trips to North Sikkim since 2012, including thousands to Gurudongmar. We acclimatise you at Lachen (2,750 m) the night before, and the ascent to Gurudongmar happens between 5 and 11 AM so you are not at altitude for more than 90 minutes. Guests with serious heart conditions, late-stage pregnancy or children under 5 should not attempt Gurudongmar.
When do the Yumthang Valley flowers actually bloom?
The peak rhododendron bloom in Yumthang Valley is from late April to mid-June, with primulas and poppies joining through May. October-November is the snow-rimmed quiet season — no flowers, but the clearest Kanchenjunga views of the year. The bloom dates vary by altitude band — we time the trip to your priority (flowers vs clarity).
Can foreigners visit North Sikkim?
Yes, with a Protected Area Permit (PAP) and a minimum of two travellers in the group. The PAP is processed through a registered Sikkim-based travel agency — we handle it. Foreigners can visit Lachen, Lachung, Gurudongmar, Yumthang and Zero Point. Tso Lhamo Lake remains closed to all tourists, Indian and foreign alike.
What about Tso Lhamo Lake — is it open?
No. Tso Lhamo Lake (5,330 m) is on the Tibet border in a sensitive military zone and is currently closed to all tourists. We do not promise Tso Lhamo to any guest. If you have seen it advertised by another operator, the permit will not be issued. Gurudongmar Lake, 30 km away, remains open and is the standard high-altitude lake visit.
Is Gurudongmar Lake currently open?
No — Gurudongmar Lake is currently closed to tourists. The Mangan district administration is planning a phased reopening for July 2026, but until that is confirmed in writing we do not promise Gurudongmar to any guest. We are not accepting Gurudongmar bookings for dates before the reopening is officially confirmed. For trips in this window we offer alternative high-altitude experiences in North Sikkim (Chopta Valley, Thangu Valley, the Yumthang and Zero Point combination) — we will be honest about this in your written quote.
What is the best month to visit North Sikkim?
October and November for the clearest Kanchenjunga views and the lowest crowds. April and May for the Yumthang Valley flower bloom and accessible snow at Zero Point. December has snow at higher altitudes and fewer travellers, but with road risk. Avoid July and August — the Singtam to Mangan stretch has landslides every monsoon and we do not promise North Sikkim during those months.
Where will we stay in Lachen and Lachung?
Lachen — at Apple Orchard, our partner property at 2,750 m, walking distance to the village centre. Lachung — at Sumi Yashshree, our long-term partner with valley-view rooms when available. Both are direct contracts — no aggregator portal mark-up. Lachen has limited hotel inventory overall (4-5 decent properties exist) and Lachung has more options, but we book the same partners every time so you get the room category you booked.
How do I reach Gangtok before the North Sikkim trip starts?
Three options: Bagdogra airport (IXB) is 124 km / 4.5 hours by road. NJP railway station in Siliguri is 119 km / 4 hours. Pakyong airport in East Sikkim is 32 km / 1.5 hours — the closest airport but with limited flights (mostly from Kolkata). We include the pick-up from any of these in the 5N+ packages.
Can I do North Sikkim self-drive?
No. North Sikkim requires Inner Line Permits that are issued only to permit-holder vehicles registered with the Sikkim Tourism Department. Even if you have your own vehicle, you cannot drive it past Chungthang without going through a registered operator. We use experienced North Sikkim drivers who have run the Mangan-Chungthang-Lachen route for years.
What is altitude sickness risk and how do you manage it?
Lachen is 2,750 m and Gurudongmar is 5,430 m. The risk is the rapid ascent on day 2. We mitigate this by: overnight at Lachen for acclimatisation, pre-dawn ascent so you spend minimal time at peak altitude (under 90 minutes), Diamox on request, and an emergency descent to Chungthang within 90 minutes if anyone shows symptoms. Our drivers carry oxygen.
Are these prices fixed or can the itinerary be customised?
Every itinerary above is customisable. We do not run fixed group departures — every trip is private and tailored to you. Swap days, add a Pelling or Darjeeling extension, upgrade hotel tier, change pick-up city — we adjust the quote and re-confirm in writing. The base routings shown are what most guests pick; yours can be different.
What happens if Gurudongmar is closed by weather?
We swap the day. If the Lachen check-post turns us back due to snow or storm, we use the day for a Chopta Valley visit (close to Lachen, also at altitude, often clear when Gurudongmar is not) and try Gurudongmar the next morning. If two consecutive days fail, we adjust the rest of the itinerary and refund the unused permit fee. We do not promise Gurudongmar — but in 12,856+ trips, the success rate is over 90%.
How do I actually book? What is the process?
Tell us your dates and any preferences (food, budget tier, mobility, kids). We send a written quote within 24 hours. You can verify us by visiting our Gangtok office (walk-ins welcome) or by video call. Once confirmed, we create a dedicated WhatsApp group with your sales coordinator, the hotel reservations team, the transport team and the tour planner. 50% advance, balance on arrival. The group stays active throughout the trip for 24/7 support.
