Nunukan

Nunukan is an administrative regency in North Kalimantan that spreads across mainland territory and several islands while bordering Malaysian states. The territory comprises a main landmass and numerous islands that together form this administrative region.

This administrative unit was created in 1999 from northern districts of a larger region and marked a significant restructuring in northern Kalimantan. Its formation was part of broader administrative reforms across the island region.

Tidung, Bajau, and Bugis communities live here and practice their own crafts and daily customs. These groups have shaped the region's identity through their distinct ways of living and working.

Ferries connect the islands to Malaysia and enable travel to nearby cities. The region has several administrative centers reachable by land and sea routes.

One island is divided by an international border, with one section belonging to Malaysia and the other to Indonesia. This shared boundary creates an unusual geographic feature that visitors often find surprising.
