Sikkim Guide: Gangtok, Lachung and Pelling in One Trip

A good Sikkim trip takes six to eight nights and links three bases: Gangtok, Lachung in the north, and Pelling in the west. Most travellers fly to Bagdogra in West Bengal or take a train to New Jalpaiguri, then drive up. Roads are scenic but slow, so give each base at least two nights.

This guide helps you decide what fits your time and how to avoid common planning mistakes.

Getting there and permits

The nearest airport for most itineraries is Bagdogra, with connections from Delhi, Mumbai, Bengaluru and Kolkata. Plan a connection if you are flying from Chennai. From Bagdogra, Gangtok is roughly four to five hours by road, longer in bad weather. Sikkim also has an airport at Pakyong, but flights are limited and can be disrupted by weather, so do not rely on it without checking.

Several areas of Sikkim, including the routes toward Tsomgo Lake, Nathu La and parts of the north, are restricted and typically need a permit arranged through local authorities or a registered operator. Rules and the list of restricted places can change, so confirm what applies before you travel. Carry photo ID and copies of any permit papers.

Gangtok: the easy first stop

Gangtok is Sikkim's capital and a practical place to settle in after the drive. Spend a day on the city itself:

• MG Marg, a pedestrian-only street lined with cafés and shops, good for an evening walk.
• Rumtek Monastery, one of the best-known monasteries in the state, about an hour's drive away.
• Enchey Monastery and the viewpoints above the city on a clear morning.

Day trips from Gangtok often include Tsomgo (Changu) Lake, a high-altitude lake that can freeze in winter. Permits and road conditions apply, and access is sometimes closed after snow or landslides. Altitude can bring headaches, so go slowly and drink water.

Try momos, thukpa and sel roti. Local tea and small cafés make good rest stops.

Lachung and Yumthang Valley

Lachung is in North Sikkim, usually a four to five hour drive from Gangtok depending on conditions. The village sits among steep mountains and waterfalls, and it makes a quiet base compared with Gangtok.

From Lachung, the highlight is Yumthang Valley, a high valley with rhododendrons in spring, and snow views at other times. It is roughly an hour or so beyond Lachung by road. Some trips continue to Zero Point for snow, but access depends on the season and permits.

Keep warm clothing handy even in summer. The roads in the north can be affected by landslides, especially after rain, so build a spare day into your plan.

Pelling and West Sikkim

Pelling is known for its mountain view of the Kanchenjunga range on clear mornings. It is a small hill town, usually four to six hours from Gangtok by road, with a calm pace and several monastery and heritage stops nearby:

• Pemayangtse Monastery, an old monastery with painted interiors.
• Rabdentse ruins, remains of the former capital.
• Khecheopalri Lake, a quiet lake in a forest, associated with local beliefs.

Pelling also works as a stopover on a route from Darjeeling, which many travellers combine with Sikkim. The mountains are often cloudy in the afternoon and during the monsoon, so go early to viewpoints.

When to go

March to May is popular for rhododendrons, clear mountain days and comfortable weather in the lower towns. October and November are crisp and clear, with good mountain views. December to February is cold and can bring snow in the north, which suits some travellers but closes some roads. June to September is monsoon, with heavy rain, landslides and cloud.

Sample 7-night plan

1. Nights 1 to 2: Gangtok, local sights and Rumtek.
2. Nights 3 to 4: Lachung, with a day trip to Yumthang.
3. Night 5: Back to Gangtok, or onward toward the west.
4. Nights 6 to 7: Pelling, then return for your flight from Bagdogra.

If you have fewer days, drop Pelling and keep Gangtok plus Lachung. If you have more, add Ravangla and Buddha Park, or combine with Darjeeling.

Choosing how to travel

Hill roads suit a private car with an experienced local driver, as the driver will know current road status. Shared jeeps are cheaper but less flexible. Groups can make the logistics and permits easier, and our group tours are one way to see several of these places without planning every road yourself.
