The Malusan no-hunting area is located 24 kilometers northwest of Nahavand. For nearly 12 years, it has been recognized as a protected area due to the presence of wild sheep and goats. The area covers 10,000 hectares and includes a ranger station. It is bordered to the north by the villages of Siah Darreh and Gol Zard in Tuyserkan, to the south by the villages of Deh Sorkheh, Malusan, and Taemeh, to the west by the village of Qeshlaq Najaf, and to the east by the village of Baba Kamal in Tuyserkan.
The highest elevation in this area is 2,850 meters; it features numerous valleys and shelters, including Summer Valley, Almond Valley, Chuleh Zardeh, Cheshmeh Tushkeh Valley, and Jerkheh Dan Valley. There are many permanent and seasonal springs in this area, such as Far Esmail Khani Spring, Upper and Lower Isab Spring, and Groukaneh Spring. Seasonal springs include Mertak Spring and others.
The area is home to various plant species, including Russian knapweed, rhubarb, Spear Thistle, Shakarok, various types of wild onions, alfalfa, and borage. Shrubs such as fig, wild almond, hawthorn, ash, vine, and various types of astragalus are also found here. Due to the vegetation cover, soil erosion in the area is minimal.
Malusan can be accessed via the asphalt road from Kermanshah, 18 kilometers from Nahavand, through two routes. The first route is from the road opposite the village of Vosheh to the asphalt road towards the village of Taemeh, and from there to the Malusan heights. The second route is from the Kermanshah road via Haji Alimorad's upper road to the Vasaj road, which leads to the village and heights of Malusan.
