Mountain range of Cardó Nature · Rasquera, Ribera d'Ebre, Tarragona The Serra de Cardó is a mountain formation of the Pre-Coastal range, in the Baix Ebre, rising above Rasquera and Tivissa, in the Ribera d'Ebre. Together with the Serra del Boix, it forms the Cardó massif, which descends towards the Ebro to the west and borders the Serra de Tivissa to the east. The ridge culminates at the Creu de Santos, 942 metres high, with other peaks such as the punta de l'Agulla (687 m) and the Picossa (766 m); old paths cross it, such as the portell de Cosp, towards Rasquera and Móra d'Ebre. The Cardó-Boix ranges are included in the Plan of Natural Interest Areas of the Generalitat de Catalunya, and in the heart of the massif, accessible from Rasquera, lies the old Cardó spa, currently being converted into a hotel.
