7-Day Complete Sikkim Itinerary: Gangtok, North Sikkim & Pelling Grand Circuit

Sikkim is a Himalayan wonderland where sub-tropical bamboo forests give way to high-altitude Tibetan plateaus, roaring waterfalls, sacred glacial lakes, and the towering amphitheater of Mount Kanchenjunga. For travelers seeking the ultimate Himalayan expedition, this 7-day Grand Circuit covers the entire geographic and cultural spectrum of Sikkim: from the vibrant hill capital of Gangtok and the holy waters of Tsomgo Lake to the extreme altitudes of North Sikkim (Gurudongmar Lake and Yumthang Valley) and the spiritual heritage of South and West Sikkim (Namchi, Ravangla, and Pelling). If you are preparing your arrival route from the plains, start with our guide on how to reach Gangtok from Siliguri and Bagdogra Airport.

Route Overview & Trip Logistics

Covering over 750 kilometers across challenging mountain terrain, this circuit spans elevations from 300 meters at the plains to 5,430 meters (17,800 feet) at Gurudongmar Lake. Because North Sikkim is a restricted border region, travelers must travel in authorized 4WD vehicles (Mahindra Scorpio, Bolero, or Tata Sumo) accompanied by licensed local drivers and pre-cleared military permits. The circuit begins and ends at Bagdogra Airport (IXB) or New Jalpaiguri Railway Station (NJP).

Day 1: Bagdogra to Gangtok & Himalayan Promenade

Arrive at Bagdogra Airport or NJP Railway Station before midday and embark on the picturesque drive up NH10 alongside the emerald Teesta River. Cross the border checkpoint at Rangpo into Sikkim and climb towards Gangtok at 1,650 meters (5,410 feet). Settle into your hotel and hand over passport photos and ID copies to your tour operator to finalize your North Sikkim and Nathu La border permits. For an introduction to the capital's attractions, check our 3-day Gangtok and Tsomgo Lake itinerary.

Spend your evening strolling along the pedestrian-only MG Marg promenade. Savor steamed pork and vegetable momos, hot bowls of gyathuk, and local confectionery while browsing brass prayer wheels, hand-woven carpets, and Sikkimese organic teas.

Day 2: Sacred Tsomgo Lake & Nathu La Pass on the Old Silk Route

Depart early on Day 2 for an exhilarating excursion into East Sikkim's alpine heights. Ascend past the Kyongnosla Alpine Sanctuary to reach sacred Tsomgo Lake (Changu Lake) at 12,400 feet, where deep turquoise glacial waters reflect jagged snow peaks. Continue past the New Baba Harbhajan Singh Mandir (13,123 feet) to the historic Nathu La Pass at 14,140 feet (4,310 meters). Standing on the Old Silk Route right on the Indo-China border, you can see Chinese military bunkers and trade halls across the barbed wire. Return to Gangtok by mid-afternoon to rest and prepare for the North Sikkim expedition. Explore more regional highlights in our guide to places to visit in Gangtok and North Sikkim.

Day 3: Gangtok to Lachen via Gushing Waterfalls & Chungthang

Board your 4WD vehicle after breakfast and set off on the rugged North Sikkim Highway. The road winds through dense subtropical rainforests and sheer rock faces, passing dramatic cataracts such as Seven Sisters Waterfalls and Naga Falls. Stop at the confluence of the Lachen Chu and Lachung Chu rivers in Chungthang, where Guru Padmasambhava is said to have blessed the land.

Ascend into the high-altitude Monpa and Bhutia village of Lachen (8,838 feet / 2,694 meters), the base for Gurudongmar Lake. Discover adjacent offbeat tribal ecosystems in our guide on the Dzongu Lepcha tribal reserve in North Sikkim. Check into your cozy wooden lodge in Lachen, enjoy a warm dinner of local vegetable soup and rice, and sleep early under thick blankets to prepare for a pre-dawn wake-up.

Day 4: Extreme Altitudes at Gurudongmar Lake & Transfer to Lachung

Wake up at 4:00 AM on Day 4 for the thrilling 65 km drive to sacred Gurudongmar Lake at an astonishing 17,800 feet (5,430 meters), making it one of the highest accessible alpine lakes in the world. As you pass through the alpine plateau of Thangu and the windswept cold desert of Chopta Valley, the landscape opens into breathtaking Tibetan plateau terrain surrounded by glaciated giants like Mount Siniolchu and Mount Kanchengyao.

At Gurudongmar Lake, behold the dazzling sapphire water bordered by perpetual glaciers. Revering both Guru Nanak and Guru Rinpoche, locals believe a portion of this lake never freezes even during brutal winter sub-zero temperatures. Due to thin air, limit your stay at the lake to 30–45 minutes, then descend to Lachen for lunch. In the afternoon, take the 2-hour drive across to the picturesque alpine village of Lachung (8,610 feet), surrounded by cascading waterfalls and pine-fringed cliffs.

Day 5: Yumthang Valley of Flowers, Zero Point & Southward Transit

Set out at sunrise for Yumthang Valley (11,800 feet), famously celebrated as the 'Valley of Flowers'. In spring (April to June), the entire valley erupts in a vibrant tapestry of blooming rhododendrons, primulas, and alpine poppies. Drive 23 km further up the valley to Zero Point (Yumesamdong) at 15,300 feet (4,663 meters), where the civilian road ends near the snowfields and frozen streams of the Indo-China frontier.

Soak your hands in the natural sulfur hot springs near Yumthang before returning to Lachung for a hearty meal. In the afternoon, begin the scenic mountain descent through Mangan back towards Gangtok or the South Sikkim gateway, where you can unwind in comfortable lower-altitude valley warmth.

Day 6: South Sikkim Char Dham, Ravangla Buddha Park & Pelling

On Day 6, head into South and West Sikkim. Your first stop is Namchi to visit Siddheshwar Dham (Char Dham), a sprawling cultural complex featuring a colossal 108-foot statue of Lord Shiva perched on Solophok Hill alongside replicas of the twelve Jyotirlingas and four sacred dhams. Next, travel to Ravangla to marvel at the 130-foot Shakyamuni Buddha statue at Buddha Park (Tathagata Tsal).

Continue winding through cardamom groves to Pelling (2,150 meters) in West Sikkim. Check into your resort and visit the Chenrezig Glass Skywalk, where transparent cantilevered walkways let you gaze straight down forested ravines against unobstructed views of Mount Kanchenjunga. Discover more West Sikkim excursions in our guide to the top things to do in Pelling and route logistics in how to reach Pelling from Gangtok and Bagdogra.

Day 7: Pemayangtse Monastery, Rabdentse Ruins & Departure

Catch a breathtaking golden sunrise over Mount Kanchenjunga before checking out. Visit the 300-year-old Pemayangtse Monastery, the premier seat of the Nyingma Buddhist order in Sikkim, housing ancient thankas and the miraculous seven-tier wooden sculpture of Zandog Palri. Take a short 15-minute nature walk through chestnut woods to the stone archaeological ruins of Rabdentse, the historic second capital of the Kingdom of Sikkim overlooking the deep valley.

Begin your descent towards the plains via Legship and Jorethang, reaching Bagdogra Airport (IXB) or NJP Railway Station by late afternoon. Ensure your return flight is scheduled after 5:00 PM to accommodate mountain transit buffers.

Essential High-Altitude & Permit Guidelines

• North Sikkim Permits: Indian nationals require Protected Area Permits (PAP) for Lachen, Gurudongmar, Lachung, and Yumthang. Foreign nationals are currently permitted only up to Lachung and Yumthang Valley (in groups of two or more with a registered guide) and cannot visit Gurudongmar Lake or Nathu La.
• Altitude Sickness (AMS) Protocol: Gurudongmar Lake sits at 17,800 feet where atmospheric oxygen is roughly 50% of sea level. Drink 4–5 liters of water daily, avoid alcohol, ascend gradually, and carry portable oxygen canisters and Diamox (acetazolamide) under medical guidance.
• Sub-Zero Weather Gear: Temperatures at Gurudongmar and Zero Point regularly drop to -5°C to -15°C in autumn and winter. Pack heavy thermal base layers, a down feather parka, windproof trekking pants, fleece-lined gloves, woolen socks, and UV-blocking polarized sunglasses.
• Cash & Power Banks: Electricity and cellular networks are intermittent in North Sikkim. Carry high-capacity power banks to keep camera and phone batteries warm, and carry adequate cash for all local needs.
