What about landslides? At what time of years is it active?

Sikkim is a landslide prone area and in the monsoons many parts of Sikkim are cut off. The repairs are taken care of by the Border Roads Organisation (BRO), who does a great job of clearing the roads as fast as possible. With the border close by, it is also imperative from the defence point of view to keep the roads as clear as possible. `Transshipments’ across landslides are common and can be an adventurous experience!
