Sumin Reserve Forest ( also known as Sumen) is located about 20 km from Rangpo town in Pakyong District of the Sikkim state in India.

Very little human habitats are there inside this community reserve forest, since histrocal and socio-religious beliefs have conserved and protected this place.

The frightened king of Sikkim (or Chogyal) erected a fort to prevent the attack.

During the time of Rama Navami and for other Hindu festive occasions local pilgrims do offerings to the deity Goddess Kali.

Birds at Sumin Reserve Forest include species like the kalij pheasant, hill partridge, satyr tragopan, bar-throated minla, black-eared shrike babbler, white-crested laughingthrush, rusty-fronted barwing, Crimson-browed finch, common green magpie , long-Tailed Sibia etc.
