The highest point of the range is the 1,275 m high Muixacre, located close to the Port de Querol mountain pass in the N-232 road.

This mountain chain rises between the almost abandoned village of Vallivana and the top of the Maestrat mountains, south of the Serra del Turmell and west of the Serra de l'Espadella ranges.

The easiest route to reach the range is from Vallivana or from Morella This sparsely-populated mountain area has the most important forested zone of the region[2] with large prey birds such as the griffon vulture and wild animals like Spanish ibex, roe deer and wild boar.

The area of this range together with the neighboring Tinença de Benifassà and Serra del Turmell was declared a Site of Community Importance by the European Union under the name Tinença de Benifassà, Turmell i Vallivana.
