Kabi Langchuk
As the journey continues from Gangtok, the route meanders through small villages flanked by fields and valleys until it hits the forest grove of Kabi Langchuk, the place that saw the historic swearing of blood brotherhood between the Lepchas and the Bhutias. An event that underlines the ethos of even present day Sikkim. Stone markers were erected to keep the promise alive and stand to this day.
