There are 6 districts in Sikkim, an Indian state, each overseen by a Central Government appointee, the district collector, who is in charge of the administration of the civilian areas of the districts. The Indian army has control of a large territory, as the state is a sensitive border area. Many areas are restricted and permits are needed to visit them.
