This IBA comprises the Lo Xo Pass and Cong Troi areas in the north-west of Ngoc Linh (Kon Tum) Nature Reserve. The boundary of the IBA is difficult to define, but includes the mountains on either side of Lo Xo Pass in Dak Man and east Dak Plo communes, Kon Tum province, and parts of Phuoc My commune, Quang Nam province. Three high mountains lie within the site: Ngok Peng Pek, Ngok Ti On and an unnamed 1988 m peak. The IBA is situated in an area of the Central Highlands known as the Kon Tum plateau. The main forest type at the site is lower montane evergreen forest. Two recently described large mammal species have been recorded at the site: Truong Son Muntjac Muntiacus truongsonensis and Giant muntjac Megamuntiacus vuquangensis.
Black-crowned Barwing Actinodura sodangorum was discovered at Ngoc Linh (Kon Tum) Nature Reserve, and is found in the IBA. In addition to black-crowned Barwing, four other restricted-range bird species have been recorded at the site, qualifying the site for inclusion within the Kon Tum Plateau Endemic Bird Area.
