Top 10 Things to Do in Gangtok: Glacial Lakes, High-Altitude Border Passes, and Monasteries

Introduction: The Mystical Capital of Sikkim

Perched gracefully on a misty ridge in the Eastern Himalayas at an elevation of 1,650 meters (5,410 feet), Gangtok is the enchanting capital of Sikkim. With awe-inspiring views of the mighty Mount Kanchenjunga (8,586 meters)—the third highest mountain in the world—Gangtok seamlessly fuses vibrant Tibetan Buddhist spirituality, pristine alpine wilderness, clean modern urban infrastructure, and rich cultural warmth. As India's first 100% organic state capital, Gangtok charms travelers with its litter-free streets, blooming orchid gardens, and bustling pedestrian avenues.

Serving as the gateway to high-altitude Himalayan wonders across East, North, and West Sikkim, Gangtok offers a plethora of experiences for adventure seekers, spiritual pilgrims, and leisure vacationers alike. Whether you are arriving along the scenic Teesta River canyon via our transit guide on how to reach Gangtok from Siliguri and Bagdogra Airport or planning downstream adventures like white-water river rafting in Teesta, Gangtok is your ultimate Himalayan launchpad. Here are the top 10 things to do in Gangtok.

1. Journey to the Glacial Waters of Tsomgo Lake (Changu Lake)

Located roughly 40 kilometers east of Gangtok along the historic Old Silk Route at an altitude of 3,753 meters (12,310 feet), Tsomgo Lake (locally known as Changu Lake) is a sacred glacial body of water fed by melting Himalayan snows. Oval in shape and plunging nearly 50 feet deep, the lake reflects changing hues across seasons—from deep turquoise blue in autumn to a shimmering expanse of solid ice in winter.

Visitors can ride vibrantly decorated Himalayan yaks along the lakeshore, take the world's highest passenger ropeway (Tsomgo Ropeway) ascending to 14,500 feet for sweeping views of snowfields, and savor hot Tibetan noodle soup and butter tea at lakeside shacks. A Special Protected Area Permit (PAP) is required to visit the lake, readily arranged by registered Sikkim tour operators.

2. Stand at the Indo-China Border Post at Nathu La Pass

Perched at a dizzying elevation of 4,310 meters (14,140 feet) on the India-China border, Nathu La Pass was once a pivotal corridor of the ancient Old Silk Route through which silk, wool, and spices were traded between Lhasa in Tibet and the plains of Bengal. Reopened in 2006 for bilateral border trade, Nathu La is one of the most dramatic high-altitude border posts accessible to Indian civilians.

Standing on the windswept mountain pass, visitors can view the barbed-wire international border, the Chinese military installations, and the historic Nehru Stone commemorating Prime Minister Jawaharlal Nehru's 1958 visit on horseback. Nearby, visit the famous Baba Harbhajan Singh Mandir, a revered shrine dedicated to an Indian Army soldier believed to protect personnel guarding the treacherous Himalayan borders.

3. Experience Sacred Chants at Rumtek Monastery

Situated 24 kilometers southwest of Gangtok on an opposite hill slope, Rumtek Monastery (also known as the Dharma Chakra Centre) is the largest and most significant Tibetan Buddhist monastery in Sikkim. Built in the 1960s under the guidance of the 16th Gyalwang Karmapa, Rangjung Rigpe Dorje, the monastery serves as the main seat-in-exile of the Karma Kagyu lineage.

The monastery is a stunning triumph of traditional Tibetan architecture, featuring vibrant multi-colored murals, intricate thangka tapestries, gilded wood carvings, and a golden stupa containing the sacred relics of the 16th Karmapa. Listening to the resonant chanting of monks accompanied by deep Tibetan horns (dungchen) and cymbals inside the main prayer hall is a deeply moving spiritual experience.

4. Stroll and Dine Along the Pedestrian-Only MG Marg

The social and culinary epicenter of Gangtok is Mahatma Gandhi Marg (MG Marg), a beautifully paved, vehicle-free promenade lined with Victorian street lamps, wrought-iron benches, vibrant flowerbeds, and bustling multi-story shops. Embodying Gangtok's proud eco-friendly ethos, smoking, littering, and vehicular traffic are strictly prohibited.

MG Marg is a haven for foodies and shoppers. Key experiences include:

• Savoring Authentic Momos: Taste succulent steamed beef, pork, chicken, or cheese momos served with fiery fermented chili-tomato dipping sauce at legendary spots like Roll House and Taste of Tibet.
• Thukpa and Gyathuk: Warm up with hearty Himalayan noodle soups cooked in fragrant bone broths with wild mountain herbs.
• Sikkimese Tea and Bakeries: Relax at vintage cafes like Baker's Cafe with freshly brewed Temi Tea (Sikkim's award-winning tea estate) and artisan pastries.
• Handicraft Shopping: Purchase authentic Sikkimese prayer wheels, handwoven Lepcha shawls, Thangka paintings, and wooden Choktse tables.

5. Ride the Gangtok Cable Car (Ropeway)

For a thrilling bird's-eye perspective of the city, board the Gangtok Ropeway, a 1-kilometer bi-cable zig-zag passenger cable car that glides from Deorali market up to the Tashiling Secretariat in upper Gangtok.

As the cabin soars over deep forested gorges, residential terraced hillsides, and cascading mountain rivulets, passengers are treated to panoramic views of the entire Gangtok valley and the distant snow-capped peaks of the Kanchenjunga range.

6. Admire Ban Jhakri Falls and Shamanic Energy Park

Tucked inside a lush forested valley 7 kilometers from Gangtok, Ban Jhakri Falls is a 100-foot natural cascade set within a beautifully landscaped 2-acre theme park celebrating Sikkim's traditional shamanic heritage (Jhakri culture).

The park features cobblestone pathways, bamboo footbridges, solar-powered energy exhibits, and intricate sculptures depicting traditional forest healers, nature spirits, and tribal folklore. It is a fantastic family-friendly excursion where children can enjoy paddle boating on the lagoon and adventure rope courses.

7. Seek Sunrise Views of Mount Kanchenjunga from Ganesh Tok and Hanuman Tok

Perched high above Gangtok at altitudes exceeding 2,000 meters, Ganesh Tok and Hanuman Tok are two revered hilltop viewpoints dedicated to Lord Ganesha and Lord Hanuman, maintained impeccably by the Indian Army.

Arriving at either viewpoint at daybreak rewards early risers with the most majestic sunrise spectacle in Sikkim. As the first rays of morning sun strike the five snowy summits of Mount Kanchenjunga (8,586m), Mount Siniolchu, and Mount Pandim, the icy glaciers glow in brilliant shades of pink, fiery amber, and molten gold against clear sapphire skies.

8. Day Trips to Pelling, Yuksom, and Darjeeling

Gangtok's central highway network provides seamless access to the wider Himalayan circuit. Travelers can head west to explore the skywalk and monasteries described in our guide on how to reach Pelling or journey to Sikkim's first historic coronation capital detailed in the Yuksom heritage guide.

Alternatively, you can travel south across the Teesta valley into the tea garden hills of West Bengal via our route guide on how to reach Darjeeling from Kolkata and Bagdogra Airport.
