Benlloc is located in the center of the Pla de l'Arc, itself in the center of Castellón. The town is an example of modern architecture and rural urbanism. It is divided into a modern and a historical section, with these subdivided into quadrants, some containing basic services with others containing plazas, houses and a fortified church. Benlloc shares a border with Alcalà de Xivert, Cabanes, Serra d'En Galceran, Torreblanca, Vall d'Alba, and Vilanova d'Alcolea.
The Via Augusta passes through the city, and remains of ancient Roman times are scattered throughout the surrounding region.
The economy of Benlloc is focused around agricultural production and cattle. Due to mostly dry land in Benlloc, production of fruits and vegetables is made possible due to irrigation techniques. Pig production and poultry are also important industries. The craft industry is centered on turrónes, carpentry, construction and locksmithing.
