Planning a North Sikkim holiday from Kolkata requires a little more preparation than a regular hill-station trip. Long mountain drives, high-altitude destinations, permits, changing weather and road conditions all need to be considered while creating a practical travel plan. A well-planned North Sikkim 5 Nights 6 Days Itinerary allows travellers to explore Gangtok, Lachen and Lachung while keeping enough time for the return journey.
For travellers coming from Kolkata, the main road journey generally begins after reaching New Jalpaiguri (NJP), Bagdogra or Siliguri. From there, the itinerary moves to Gangtok before continuing towards North Sikkim. The route then covers Lachen and Lachung, includes a full day around Lachung, and finally returns to Gangtok before the onward drop.
If you prefer to arrange the accommodation, transfers and sightseeing as one coordinated trip, you can also explore our North Sikkim Tour Package from Kolkata – 5 Nights 6 Days.
This itinerary follows a practical six-day route and can be adjusted according to permits, weather, road conditions and local travel regulations.
North Sikkim Itinerary: 5 Nights 6 Days at a Glance
A five-night, six-day North Sikkim itinerary is structured around two important parts of the journey: Gangtok and North Sikkim. The first day is kept for travelling from NJP, Bagdogra or Siliguri to Gangtok. The following days gradually take you deeper into the mountains, first to Lachen and then Lachung, before returning to Gangtok.
The overall route can be summarised as follows:
| Day | Route | Overnight Stay | Main Plan |
| Day 1 | NJP / Bagdogra / Siliguri → Gangtok | Gangtok | Pickup and transfer to Gangtok; check-in and leisure |
| Day 2 | Gangtok → Lachen | Lachen | Scenic drive towards North Sikkim |
| Day 3 | Lachen → Lachung | Lachung | North Sikkim sightseeing and transfer to Lachung |
| Day 4 | Lachung | Lachung | Full-day sightseeing and exploration |
| Day 5 | Lachung → Gangtok | Gangtok | Return journey towards Gangtok |
| Day 6 | Gangtok → NJP / Bagdogra / Siliguri | — | Drop for train, flight or onward journey |
This sequence keeps the high-altitude North Sikkim portion between the two Gangtok stays. Since mountain travel can be affected by weather, road conditions and permits, the exact sightseeing sequence may change.
Day 1 – NJP, Bagdogra or Siliguri to Gangtok
Your North Sikkim 5 Nights 6 Days Itinerary begins after you arrive at NJP Railway Station, Bagdogra Airport or Siliguri. From the pickup point, start your road journey towards Gangtok, the capital of Sikkim and the first overnight destination of this itinerary.
The drive gradually takes you from the plains into the Himalayan foothills. As you move towards Gangtok, the landscape changes from relatively flat terrain to winding mountain roads, green hills and scenic valleys. Depending on your arrival time and traffic conditions, the journey may take several hours.
After reaching Gangtok, check in to your hotel and take some time to relax. Since the following day begins the journey towards Lachen and North Sikkim, keeping the first evening comfortable is more practical than planning an extensive sightseeing schedule.
Evening in Gangtok
If you reach Gangtok with enough time, you can spend the evening at leisure. You may explore the nearby market area, enjoy the local atmosphere or simply rest at the hotel after the journey from NJP, Bagdogra or Siliguri.
There is no need to rush through sightseeing on the first day. The main purpose of Day 1 is to reach Gangtok comfortably and prepare for the longer mountain journey ahead.
Overnight stay: Gangtok
Day 2 – Gangtok to Lachen via Chungthang and Seven Sisters Waterfall
After breakfast, check out from your Gangtok hotel and begin the journey towards Lachen. This is the first major road journey into North Sikkim and introduces you to the changing Himalayan landscape.
As you leave Gangtok, the road gradually enters more remote mountain areas. Along the way, you can experience forested hills, mountain streams, valleys and winding roads. The journey is as much a part of the North Sikkim experience as the destinations themselves.
One of the planned sightseeing stops on this route is Seven Sisters Waterfall, a scenic waterfall surrounded by the Himalayan landscape. The journey also passes through Chungthang, an important point on the North Sikkim route where the roads towards Lachen and Lachung branch off.
The exact stopping time at sightseeing points can depend on traffic, weather, road conditions and local instructions, so it is better to keep the schedule flexible.
Reaching Lachen
After completing the en-route sightseeing and continuing through the mountain roads, proceed towards Lachen.
Lachen is an important overnight base for exploring the higher areas of North Sikkim. After reaching the town, check in to your accommodation and take some time to rest.
The evening should be kept relaxed because the following day involves an early journey towards Gurudongmar Lake, one of the major highlights of the North Sikkim circuit.
Temperatures in Lachen can also be considerably colder than in Gangtok, particularly during winter and at night. Keep your warm clothing and other essential items easily accessible.
Overnight stay: Lachen
Day 3 – Lachen to Gurudongmar Lake, Return to Lachen and Transfer to Lachung
Day 3 is one of the most important days of your North Sikkim itinerary. The day begins with an early departure from Lachen for Gurudongmar Lake, one of the best-known high-altitude attractions in North Sikkim.
The journey towards the lake takes you through increasingly rugged mountain terrain. As you gain altitude, the landscape changes from forested mountain slopes to open valleys, rocky terrain and expansive Himalayan views.
Gurudongmar Lake is located at a very high altitude and is known for its striking surroundings and spiritual significance. Because of the elevation and the length of the journey, the sightseeing schedule should be followed according to local conditions and the guidance of the driver.
After spending time at Gurudongmar Lake, return towards Lachen. Following the return to Lachen, continue the journey towards Lachung.
This makes Day 3 a full travel-and-sightseeing day, combining the Gurudongmar Lake excursion with the transfer from Lachen to Lachung. Reaching Lachung later in the day, check in to your accommodation and rest.
Scenic Stops Along the Route
The route between Lachen, Gurudongmar Lake and Lachung offers some of the most dramatic scenery of the trip. Depending on road and weather conditions, travellers can enjoy views of mountain valleys, streams, rugged slopes and the changing landscape of high-altitude North Sikkim.
Rather than trying to stop at every viewpoint, it is better to follow the planned route and allow sufficient time for the return journey. Mountain roads can be unpredictable, and visibility may change quickly with weather conditions.
The journey itself becomes an important part of the experience, especially as the landscape around Gurudongmar is very different from the greener surroundings closer to Gangtok.
Overnight stay: Lachung
Day 4 – Lachung to Yumthang Valley and Back to Lachung
Day 4 is dedicated to sightseeing around Lachung and is the main full-day exploration day of the itinerary.
After breakfast, start your journey from Lachung towards Yumthang Valley, one of the most popular natural attractions in North Sikkim. The valley is known for its wide mountain landscape, alpine surroundings, streams and seasonal flowers.
The drive from Lachung to Yumthang is itself scenic, with the road passing through mountain terrain and changing Himalayan landscapes. Depending on the season and accessibility, the appearance of the valley can be very different—from snow-covered surroundings during colder months to greener landscapes and seasonal flowers during warmer periods.
After spending time at Yumthang Valley, begin the return journey towards Lachung.
Enjoying the Himalayan Landscape
The experience of Yumthang is not limited to reaching one particular viewpoint. The surrounding mountains, valley floor, streams and changing weather make the entire journey visually appealing.
Visibility can vary during the day, so do not be surprised if the landscape looks different from one stop to another. Keeping some flexibility in the sightseeing schedule allows you to enjoy the valley without rushing.
The exact sightseeing experience also depends on the season. Snow, rainfall, greenery and seasonal flowers can all influence the appearance of the region.
After completing the day’s sightseeing, return to Lachung.
Overnight stay: Lachung
Day 5 – Lachung to Gangtok
After breakfast, check out from your Lachung accommodation and begin the return journey towards Gangtok.
By this stage of the trip, you will have completed the main North Sikkim sightseeing around Lachen and Lachung. Day 5 is therefore primarily a return-transfer day, allowing you to gradually travel back towards the lower-altitude areas.
The route offers another opportunity to enjoy the mountain scenery. Depending on weather and visibility, the same landscapes you passed earlier in the journey may look completely different on the return.
Since the drive can take a significant part of the day, it is better not to overload the itinerary with additional sightseeing. The priority is to reach Gangtok comfortably.
Once you arrive, check in to your hotel and spend the evening at leisure.
Why Gangtok Matters in This North Sikkim Itinerary
The final night in Gangtok creates a useful buffer between the North Sikkim mountain journey and your onward journey towards NJP, Bagdogra or Siliguri.
Travelling directly from Lachung to the railway station or airport on the same day as a train or flight could make the final connection unnecessarily tight. Staying overnight in Gangtok makes the departure day more manageable and gives you time to rest after several days of mountain travel.
If you have enough free time in the evening, you can explore nearby areas of Gangtok at your own pace. Otherwise, simply relaxing at the hotel is a good option before the final road journey.
Overnight stay: Gangtok
Day 6 – Gangtok to NJP, Bagdogra or Siliguri
After breakfast, check out from your Gangtok hotel and begin the final transfer towards NJP Railway Station, Bagdogra Airport or Siliguri.
The journey takes you back through the mountain roads towards the plains. Keep sufficient buffer time between your expected arrival and your train or flight because traffic, weather and road conditions can affect travel time.
Travellers returning to Kolkata by train can continue their onward journey from NJP, while those travelling by air can proceed to Bagdogra Airport.
After reaching your drop point, your North Sikkim 5 Nights 6 Days Itinerary comes to an end.
How to Reach North Sikkim from Kolkata for This Itinerary
Although the itinerary is planned as a six-day tour, the actual road portion starts from NJP, Bagdogra or Siliguri rather than directly from Kolkata.
Travellers from Kolkata can reach NJP by train or Bagdogra by flight and then continue by road towards Gangtok. Siliguri is another possible road-transport starting point.
The train option is popular among travellers who prefer an overnight journey, while flying to Bagdogra can reduce the travel time from Kolkata.
For a detailed explanation of the available routes, train and flight options and the onward road journey, see How to Reach North Sikkim from Kolkata.
The important point is to plan your arrival time carefully. Your Day 1 transfer to Gangtok should leave enough time for a comfortable journey rather than creating a rushed connection.
What Is the Cost of a North Sikkim 5 Nights 6 Days Trip?
The total cost of a North Sikkim trip from Kolkata can vary depending on the season, number of travellers, accommodation, transportation, travel dates and package inclusions.
For this particular itinerary, travellers should consider both the Kolkata-to-North Bengal journey and the Sikkim road package while calculating the overall budget.
Common cost components include:
- Train or flight fare between Kolkata and NJP/Bagdogra
- Pickup and drop transportation
- Accommodation in Gangtok, Lachen and Lachung
- Meals according to the selected package
- Local sightseeing transportation
- Applicable permits and charges
- Personal expenses
- Additional expenses caused by changes in travel arrangements
For a more detailed breakdown of the expenses and factors affecting the budget, read North Sikkim Tour Cost from Kolkata 2026.
It is also important to compare the inclusions of different packages. A lower starting price does not necessarily mean the same services are included in every package.
Best Time for a North Sikkim Itinerary
The best time for this itinerary depends on the type of experience you want from North Sikkim. The region changes significantly throughout the year, and weather conditions can influence both scenery and road accessibility.
Spring and summer can offer different experiences from autumn and winter, while the monsoon period may bring increased rainfall and challenging road conditions.
Winter can be particularly attractive for travellers interested in snow-covered Himalayan landscapes, but cold temperatures and road accessibility need to be considered carefully.
Because your itinerary includes both Gangtok and high-altitude destinations such as Lachen and Lachung, it is important to check seasonal conditions for the entire route rather than looking only at Gangtok weather.

Important Things to Know Before Starting the Trip
North Sikkim is a high-altitude mountain destination, so travellers should prepare differently from a standard city or hill-station holiday.
Keep Your Schedule Flexible
The itinerary provides a planned route, but the actual schedule can change because of weather, road conditions, permits and local regulations.
Carry Warm Clothing
Temperatures in Lachen and Lachung can be considerably lower than in Kolkata and Gangtok. Layered warm clothing is useful throughout the year, with additional protection needed during colder months.
Keep Documents Ready
Carry valid identification and other documents required for hotel check-in and permits. Permit requirements can vary depending on the destinations included in your trip.
Prepare for Long Mountain Drives
Several days of this itinerary involve road travel. Carry water, light snacks and essential personal items where they are easily accessible.
Give Importance to Altitude
Lachen and Lachung are at significantly higher elevations than Gangtok. Take adequate rest and avoid unnecessary physical exertion. If you feel unwell at altitude, inform your driver or local support team and seek appropriate medical advice.
Keep Buffer Time for the Return
Do not plan a very tight train or flight connection immediately after a long mountain drive. Keeping extra time can make the final day considerably less stressful.
Why This North Sikkim Itinerary Works Well
The structure of this itinerary is designed around the geography of the region. Instead of trying to cover North Sikkim in a short period, the journey gradually moves from NJP/Bagdogra to Gangtok, then towards Lachen and Lachung, before returning through Gangtok.
The Gangtok stay at the beginning provides a comfortable starting point before entering the higher mountain areas. The two-night Lachung portion gives you a dedicated day for sightseeing rather than making the entire North Sikkim visit dependent on a single rushed day.
The final Gangtok stay also creates a buffer before the journey back to NJP, Bagdogra or Siliguri.
For travellers from Kolkata, this structure combines the necessary travel time with sightseeing while keeping the route relatively straightforward.
Practical Tips for Your North Sikkim Itinerary
A little preparation can make the entire journey smoother.
Before leaving Kolkata, confirm your train or flight, hotel bookings and Sikkim transportation arrangements. Keep your identification documents accessible and check the latest permit requirements.
During the road journey, avoid carrying unnecessarily heavy luggage. A smaller day bag containing warm clothing, medicines, water and essential personal items can be useful.
Keep your expectations flexible as well. Mountain destinations cannot always be planned with the same precision as city holidays. Weather, road conditions and local restrictions may affect the sequence or duration of sightseeing.
It is also worth checking the seasonal conditions before finalising your dates. A route that is accessible during one period may have different conditions at another time of year.
Most importantly, follow the instructions of your driver and local authorities, particularly in high-altitude and restricted areas.

Final Thoughts

Starting from NJP, Bagdogra or Siliguri, the route moves through Gangtok to Lachen and Lachung before returning to Gangtok and finally heading back towards the plains.
The combination of two nights in Lachung, a stay in Lachen and Gangtok stays on either side of the North Sikkim section allows the trip to include both mountain exploration and necessary travel time.
