The Serra d'Irta stretches in a northeast-southwest direction south of the Vinaròs plain, its northern limit.

It is located right by the Mediterranean coastline, rising on the eastern side of the road between Barcelona and Valencia.

This mountain range is covered with Maquis shrubland, including Juniperus oxycedrus, Calicotome spinosa, Pistacia lentiscus and Anthyllis cytisoides shrubs.

Some of the lower slopes facing inland are planted with olive, almond and carob trees.

[1] It is a southern prolongation of the Catalan Pre-Coastal Range that formed 25 million years ago as part of the Alpine orogeny.
