Located in the northwest corner of Rincon de Ademuz, it is mountainous with elevation ranging between 800 and 1,550 metres (2,600 and 5,100 ft).

Ebrón River crosses the territory from northwest to southeast, flowing into Turia, the boulevard of Palomarejos runs north and comes to the precipice of the Canaleja.

Farther afield to the west, the municipality borders Salvacañete in the province of Cuenca, Castilla-La Mancha; Tormón, Veguillas de la Sierra, El Cuervo, Tramacastiel and Libros of the province of Teruel, Aragon to the north and the north-east.

The township has remained virtually unchanged since medieval times and has only been a municipality at the expense of the territory of Torrebaja.

Castielfabib shares with the other towns of Rincon de Ademuz several recipes such as gachas (porridge), puchero and others, in which pork and its derivatives are central.

Almond, apple and other fruits are grown in the fertile plain of the River Ebrón and they are a key ingredient in the local bakery.
