How to Reach Sikkim from Kolkata: Your Complete Travel Guide
Sikkim, with its snow-capped peaks, alpine lakes, and serene monasteries, is a dream destination for travelers. For residents of Kolkata, it is the perfect escape from the city's heat and hustle.
Because Sikkim is a mountainous state, there is no direct broad-gauge train network to its capital, Gangtok. The journey typically involves reaching a major transit hub in the foothills—like New Jalpaiguri (NJP) or Bagdogra—and taking a scenic road trip up the mountains.
Here is your complete guide on how to reach Sikkim from Kolkata by train, flight, and road.
1. Kolkata to Sikkim by Train (The Most Popular Choice)
Traveling by train is the most preferred and budget-friendly way to begin your journey to Sikkim.
The Route: You will need to book a train from Kolkata (Howrah, Sealdah, or Kolkata Station) to New Jalpaiguri Railway Station (NJP). NJP is the primary transit hub connecting the plains of Bengal to the hills of Sikkim and Darjeeling.
Top Trains from Kolkata to NJP:
Vande Bharat Express (Howrah to NJP): The fastest option, completing the journey in about 7.5 hours. It operates during the day, six days a week.
Darjeeling Mail: A classic overnight train from Sealdah. You sleep through the journey and wake up fresh in NJP by morning.
Padatik Express: Another excellent overnight option departing from Sealdah.
Shatabdi Express: A reliable daytime train departing from Howrah.
The Final Leg: NJP to Sikkim
Once you step off the train at NJP, the real mountain adventure begins. The distance from NJP to Gangtok is about 120 km, which takes around 4.5 to 5 hours by road via the NH10 highway.
To ensure a smooth transition from the plains to the hills, you can pre-book a private cab directly from the station. Our fleet at Darjeeling Sikkim Taxi includes vehicles with both West Bengal (WB) and Sikkim (SK) commercial registrations. This gives you a major advantage: a direct, uninterrupted ride from NJP straight to your hotel in Sikkim, without the usual hassle of unloading luggage and changing cabs at the Rangpo border check-post.
2. Kolkata to Sikkim by Flight (The Fastest Route)
If you are short on time, flying is your best bet.
The Route: You have two options when flying from Netaji Subhash Chandra Bose International Airport (CCU) in Kolkata.
Option A: Fly to Bagdogra Airport (IXB) - Highly Recommended: Bagdogra is the most reliable airport for the region. Multiple daily flights operate between Kolkata and Bagdogra, and the flight takes just about an hour. From Bagdogra, Gangtok is approximately 125 km away (a 4.5 to 5-hour drive).
Option B: Fly to Pakyong Airport (PYG): Pakyong is a stunning tabletop airport located just 30 km from Gangtok. While it is closer, flights here are highly weather-dependent and frequently face cancellations due to poor visibility and Himalayan cloud cover.
The Final Leg: Bagdogra to Sikkim
Similar to the NJP route, landing in Bagdogra requires a road transfer. The drive takes you through the beautiful Mahananda Wildlife Sanctuary and along the winding Teesta River. Pre-booking a dedicated airport transfer ensures your vehicle is ready the moment you exit the terminal, letting you bypass the chaotic local taxi queues.
3. Kolkata to Sikkim by Road (For Driving Enthusiasts)
For those who love a good road trip, driving from Kolkata to Sikkim is an adventure in itself.
The Route: The drive from Kolkata to Siliguri/NJP covers approximately 580 to 600 kilometers via the NH12 highway. The journey takes about 14 to 16 hours depending on traffic.
Suggested Halt: Many travelers break the journey with an overnight stay in Malda or Raiganj before pushing forward to Siliguri the next morning.
From Siliguri, you will take the NH10 highway, which runs parallel to the Teesta River, leading you straight into Sikkim.
Note: Driving in the mountains requires experience handling steep inclines and sharp hairpin bends. If you are not confident driving in the hills, it is best to park your vehicle in Siliguri and hire a local hill-expert taxi for the Sikkim leg of the tour.
💡 Himalayan Travel "Pro-Tips" for Your Journey
Secure Your Permits Early: Sikkim shares international borders, so certain areas (like Tsomgo Lake, Nathula Pass, and all of North Sikkim) require Protected Area Permits (PAP). Carry at least 4-6 passport-sized photos and original + photocopies of your Voter ID or Passport (Aadhar cards are not accepted for permits in Sikkim).
Consolidate Your Logistics: Instead of booking a station transfer, a hotel, and sightseeing cabs separately, look for comprehensive taxi packages. Keeping the same dedicated vehicle for your entire trip saves money and eliminates daily stress.
Watch the Clock: The mountains get dark early. Try to schedule your arrival at NJP or Bagdogra before 2:00 PM so you can safely reach your hotel in Sikkim before nightfall.
