This teahouse-style trek traverses the majestic Sandakphu Singalila Ridge, a north–south mountain ridge along the borders of West Bengal, Sikkim and Nepal. It is the setting for one of the most scenically rewarding expeditions in the entire Himalayas, with picturesque views of Kangchenjunga (the third highest mountain in the world) and more distant views of Everest and Makalu (the fifth highest mountain in the world). Offering panoramic views of Sikkim as well as Nepal, this pristine trail lies inside Singalilla National Park, where travellers can catch a glimpse of rare wildlife, more than 600 varieties of blooming orchids and exotic birds.
