This recently opened trek route encompasses the area southwest of Dzongri and as defined by its name, includes several days of hike traversing the Singalila Range, the lesser mountain chain that rises from the northern hills of Darjeeling District and extends to converge with the Khangchendzonga (or Kanchenjunga) massif. The Singalila is also the divide that demarcates the western borders of Sikkim and Darjeeling with Nepal. As one traverses this razor-edged borderline ridge, spectacular views abound on both sides with rare species of rhododendron in bloom (at the right season), and an occasional herd of yaks with its herder will be your only source of contact with civilization for quite a number of days.
