Darjeeling Himalayan hill region is situated on the north-western side of the state. This region belongs to the Eastern Himalaya range. The entire Darjeeling district except the Siliguri subdivision and a narrow northern part of Jalpaiguri district constitutes the region. It starts abruptly from the Terai region. The deep gorge of Teesta River, which runs from north to south has divided this mountainous region into two parts: the Singalila range and the Darjeeling range. The Singalila range is located along the border of Darjeeling and Nepal; it has four important peaks - Sandakfu, Falut, Sabargram and Tonglu. Among the Himalayan ranges of this region, Singalila range hosts Sandakfu which at is the highest point of West Bengal.Also to mention Sandakfu & Phalut are the only place in West Bengal from where Mt. Everest is visible. Two high peaks, Tiger Hill and Ghoom are seen near the town of Darjeeling. Many ranges branch off in different directions from Tiger Hill. Durpindara is an important mountain in the eastern part of the mountainous region. A few hills also occur in the Terai or Dooars region at the foot of the Himalayas. Some remnants of the Siwaliks can be seen in the Jalpaiguri district, where they are known as the Buxa-Jayanti Hills.
