Getting from Delhi to Sikkim – Main Options

Flight

Flying is the fastest and most convenient way to reach Sikkim from Delhi, especially for those with limited time. While Sikkim's Pakyong Airport is operational, most travelers use Bagdogra Airport in West Bengal as the main gateway.

• Delhi to Bagdogra flights:

  Multiple daily flights operate from Delhi's Indira Gandhi International Airport to Bagdogra Airport, taking around 3.5 to 4 hours. Airlines like IndiGo, Air India, and SpiceJet offer competitive fares ranging from ₹3,000 to ₹7,000 depending on the season.

• From Bagdogra to Gangtok:

  Bagdogra is about 125 km from Gangtok, Sikkim's capital. Shared taxis and private cabs are available outside the airport, with travel time around 4 to 5 hours via NH10. Booking a cab in advance is recommended during peak tourist seasons.

• Pakyong Airport flights:

  Pakyong Airport, located about 35 km from Gangtok, has limited flights mainly from Kolkata and Guwahati. Connecting flights from Delhi require a stopover, making Bagdogra a more practical choice for most travelers.

• Seasonal considerations:

  Flights to Bagdogra may face delays during monsoon due to weather. Early morning flights are preferred for smoother travel and better visibility on the mountain roads ahead.

Train

Train travel from Delhi to Sikkim is indirect but offers an economical and scenic route to the nearest railway stations before continuing by road.

• Nearest railway stations:

  New Jalpaiguri (NJP) and Siliguri Junction are the closest major stations to Sikkim, approximately 115 km from Gangtok. Both are well connected by trains from Delhi.

• Train options:

  The Rajdhani Express and other long-distance trains run daily from Delhi to NJP, with journey times around 30 to 36 hours. AC classes offer comfort for this long trip, with fares ranging from ₹1,500 to ₹3,500.

• From NJP to Sikkim:

  After arrival, shared jeeps, taxis, and buses connect NJP to Gangtok. The road journey takes about 4 to 5 hours via NH10, with frequent services available throughout the day.

• Booking tips:

  Book train tickets early via IRCTC, especially during holiday seasons. Opt for trains arriving in NJP by morning to avoid night travel on mountainous roads.

• Scenic route:

  The train journey through West Bengal’s plains and foothills offers lush views, especially during winter and post-monsoon seasons.

Bus

Bus travel is a budget-friendly option for those who prefer road trips and want to experience local life en route to Sikkim. However, it is a long and tiring journey.

• Delhi to Siliguri buses:

  Direct buses from Delhi to Siliguri are rare; most travelers take buses to Kolkata or New Jalpaiguri first. Private Volvo and government buses operate on these routes, with fares from ₹1,000 to ₹2,000.

• Siliguri to Gangtok buses:

  From Siliguri or NJP, Sikkim government and private buses run frequently to Gangtok. The journey takes 4 to 5 hours, costing ₹150 to ₹300.

• Bus types and comfort:

  Volvo buses offer more comfort but are limited. Ordinary and semi-deluxe buses are common but can be crowded and less comfortable for long trips.

• Travel duration and breaks:

  The entire bus journey from Delhi to Gangtok can take 36 to 48 hours, including transfers. Plan for overnight stops in Siliguri or NJP to rest.

• Seasonal advice:

  Avoid traveling by bus during heavy monsoon months due to landslides and slippery roads in the hills.

Car / Self-Drive

Driving from Delhi to Sikkim is an adventurous choice, ideal for travelers who enjoy road trips and want to explore en route. The distance is approximately 1,500 km, requiring 30 to 35 hours of driving time.

• Route details:

  The most common route is via NH44 to Siliguri, then NH10 to Gangtok. Key cities on the way include Lucknow, Gorakhpur, and Siliguri, where you can plan rest stops.

• Road conditions:

  The plains section has good highways, but the mountainous roads near Sikkim can be narrow and winding. Drive cautiously, especially during night or monsoon.

• Permits:

  Indian nationals do not need special permits to enter Sikkim, but foreign tourists must obtain an Inner Line Permit (ILP) at entry points like Rangpo or Gangtok.

• Fuel and rest stops:

  Fuel stations are available along NH44 and NH10, but fewer in the hills. Plan refueling in Siliguri or Rangpo. Rest stops include popular dhabas and restaurants offering local cuisine.

• Seasonal considerations:

  Avoid driving during heavy rains or winter fog. Early morning starts help avoid traffic and ensure daylight driving in hilly areas.
