Best Trekking Routes in Sikkim: Himalayan Adventures for Brave Hearts

Nestled in the lap of the Eastern Himalayas and bordered by Nepal, Bhutan, and Tibet, Sikkim is often called the “Himalayan Shangri-La.”

Its pristine valleys, rhododendron-clad slopes, glacial lakes, and towering snow peaks make it one of India’s most rewarding trekking destinations. From short beginner-friendly trails to challenging high-altitude expeditions, Sikkim offers something for every adventure seeker.

Here are the most iconic and beautiful trekking routes in Sikkim:

 1. Goecha La Trek

Altitude: 4,940 m (16,207 ft)  
Duration–11 days  
Difficulty: Moderate to Difficult  
Best time: April–May (spring rhododendrons) & October–November  

The Goecha La Trek is arguably the most popular trek in Sikkim, offering a jaw-dropping close-up view of the world’s third-highest peak, Mt. Kanchenjunga. The trail winds through the biodiverse Kanchenjunga National Park, bursting with colourful rhododendrons in spring, alpine meadows, sacred lakes (especially Samiti Samiti Lake), and suspension bridges over gushing rivers. Sunrise from Viewpoint 1 at Goecha La, with the golden light on Kanchenjunga and Pandim, is an unforgettable experience.

 2. Kanchenjunga Base Camp Trek (Sikkim side)

Altitude: 5,143 m (South Base Camp)  
Duration: 12–15 days  
Difficulty: Difficult  
Best time: March–May & September–November  

One of the most pristine and least-crowded high-altitude treks in India. This remote journey takes you to the foot of Mt. Kanchenjunga (8,586 m) through dense forests, traditional Lepcha and Bhutia villages, and high pastures. Because the route lies in a restricted area near the Nepal and Tibet borders, trekking is permitted only with registered operators and special permits. The solitude and raw grandeur of the landscape make it truly magical.

 3. Green Lake Trek

Altitude: ~5,000 m  
Duration: 10–12 days  
Difficulty: Difficult  
Best time: April–May & October  

Starting from Lachen in North Sikkim, the Green Lake Trek is an explorer’s dream. The trail follows the stunning Zemu Glacier, surrounded by rare orchids, gigantic rhododendrons, and panoramic views of Kanchenjunga, Simvo, and Siniolchu. The emerald Green Lake at the base of Kanchenjunga’s north-east face is the ultimate reward. This is one of the least visited yet most spectacular treks in the region.

 4. Singalila Ridge Trek / Sandakphu–Phalut Trek

Altitude: 3,636 m (Sandakphu)  
Duration–7 days  
Difficulty: Moderate  
Best time: March–May & October–November  

Technically starting from Manebhanjan (West Bengal), the Singalila Ridge forms the border between India and Nepal and is easily accessible from Sikkim. The highlight? A sweeping 300-km panorama that includes four of the five highest peaks in the world — Everest, Lhotse, Makalu, and Kanchenjunga — is visible on a clear day from Sandakphu and Phalut. Red pandas, blooming rhododendrons, and charming Sherpa villages add to the charm.

 5. Dzongri Trek (Short version of Goecha La)

Altitude: 4,170 m  
Duration–6 days  
Difficulty: Moderate  
Best time:  March–May & September–November  

Perfect for those short on time, the Dzongri Trek starts from historic Yuksom (Sikkim’s first capital) and climbs through rhododendron forests to the meadows of Dzongri. Sunrise views of Kanchenjunga, Kabru, Pandim, and Rathong from Dzongri Top are simply breathtaking. Many trekkers use this as an acclimatisation route before continuing to Goecha La.

 6. Everest Singalila Trek (India–Nepal Border)

Duration: 15–20 days  
Difficulty: Moderate to Strenuous  

A rare cross-border adventure that combines the Singalila Ridge with the Everest region of Nepal. Trekkers walk from Sandakphu and Phalut in India, cross into Nepal, and continue toward Namche Bazaar, Tengboche, and even Everest Base Camp, enjoying views of Everest and Kanchenjunga from opposite sides of the range.

Sikkim’s trekking routes remain remarkably uncrowded compared to Nepal or Himachal, offering solitude, untouched nature, and some of the finest Himalayan vistas on earth. Whether you seek a short weekend escape or a challenging multi-week expedition, Sikkim has a trail waiting for you.

Remember: Most high-altitude and border-area treks require permits and must be organised through registered local agencies. Always trek responsibly and leave no trace in this fragile Himalayan paradise.
