The Serra de Cardó, located in the Baix Ebre region, is a mountain massif that offers a great variety of rock formations, Mediterranean vegetation and panoramic views. This mountain range includes the block of Cardó, which is located to the SE of the term and includes the steep Cardó valley. This rather narrow valley is drained by the Cardó ravine and extends to the Costumà fence, finally draining into the Ebro north of the town of Benifallet. Within the municipality, there is the old convent and spa of Cardó, as well as several hermitages. The Cardó massif stands out for the tip of l'Agulla and, towards the west, the Set Serres and the Som pass or tossal. To the east, we find the gates of Xàquera and Cops, through which pass several old roads that cross the massif. In addition, other peaks such as the Tossal del Caramull (421 m), the Tossa (483 m), the Mola and the Puntals are extensions of the same massif. The area is also rich in karst relief, with several springs and caves, such as the Meravelles Cave and the Marigot Cave, some of which show vestiges of ancient settlements, such as the Aumediella Cave and others. It should be noted that there are numerous tectonic faults in the Serra de Cardó, although not all of them have the same characteristics or magnitudes. This mountain range is a fascinating place for lovers of nature and trails, with great geological and historical diversity.
