Darjeeling Himalayan hill region, also known as the Darjeeling Hills or Darjeeling Himalaya, is a mountainous area on the north-western side of the state of West Bengal in India. This region belongs to the Eastern Himalaya range. The Darjeeling district except the Siliguri subdivision and the entire Kalimpong district constitute this region. It arises abruptly from the Terai region. The region slopes from a south to north direction. The river Teesta divides the region in two parts — the region to the east of Teesta and the region to the west of Teesta.

This is the highest region of the Darjeeling Himalayan Hill Region. Two distinct ranges are visible here — the Singalila range and the Darjeeling-Kurseong range.

The Singalila range is on the western limit of the region and separates Nepal from West Bengal. Singalila National Park is situated here. The four highest peaks of this range are:

  3. Tonglu (3,036 m)
  4. Sabargram (3,543 m)
