The Vladeasa Mountains are the northernmost of the three high central massifs of the Western Transylvanian (Apuseni) Mountains. The highest peak is Vladeasa Peak, with an elevation of 1,836 m. To the north, the massif extends to Crisul Repede River. To the south, Crisul Pietros River – Boga Creek – Varasoaia Saddle – Somesul Cald River separate it from the Bihor Mountains. The western border with Padurea Craiului Mountains is represented by Iada Valley and Iedutului Valley, and the eastern border by the peaks situated to the east of Sacuieu Valley and Hentului Valley.
This delimitation is based on geographic criteria. Draganului and Hentului valleys divide the mountains into three main divisions: a western part called the Iadului Mountains, a central part which is the Vladeasa Massif and an eastern part, named the Hentului Ridge.
The Vladeasa Mountains are fragmented by Draganului and Sacuieul valleys into three north-to-south divisions. The two valleys gather the waters of the mountain almost entirely and flow into Crisul Repede River, facilitating access from the north towards the heart of the mountain. Dragan (Floroiu) Lake and Dam on Draganului Valley covers 290 ha, with 110 million cubic meters of water.
