Nestled deep within the pristine wilderness of North Sikkim, Green Lake is one of the most spectacular yet least explored trekking destinations in the Indian Himalayas. Surrounded by towering snow-covered peaks, ancient forests, alpine meadows, and breathtaking glaciers, Green Lake offers an unforgettable adventure for travelers seeking an offbeat Himalayan experience.
Located at the base of the mighty Mount Kanchenjunga, the world's third-highest mountain, Green Lake is a paradise for trekkers, nature enthusiasts, photographers, and adventure seekers. Unlike the popular tourist destinations of Gangtok, Tsomgo Lake, and Yumthang Valley, Green Lake remains untouched by mass tourism, making it one of the most rewarding trekking experiences in Northeast India.
If you're looking for a true Himalayan adventure in 2026, this comprehensive travel guide by SortMyTrip will help you plan the perfect Green Lake expedition.
