Tharpu to Illam Trek is a nice option to have a day out. Kanchenjunga is the third-highest mountain in the world situated partially in Nepal and in Sikkim, India. It rises with an altitude of 8,586 m (28,169 ft.) in a section of the Himalayas called Kanchenjunga Himal that is limited in the west by the Tamur River, in the north by the Lhonak the Chu and Jongsang La, and in the east by the Teesta River.
The Low route of the GHT starts magnificently with an incredible view of the Kanchenjunga and Makalu Barun range from Phalut at the border with Sikkim India.
The area is rich in flora and fauna such as snow leopards, Tibetan wolves, and red pandas at large on the high mountain slopes, pine forests, and bamboo jungle. During spring, you get to see 40 species of rhododendron in bloom. You will get the opportunity to explore and experience typical Nepali village life along the trail. While trekking you pass fascinating villages, tea plantation areas, terraced fields, and crossing some suspension bridges along the way.
