The Ebro Delta stretches across the counties of Baix Ebre and Montsìa, along the Costa Dorada of Tarragona, Catalonia, Spain. At the top is the mouth of the Ebro, the richest river in Spain, which has formed the delta over the centuries. Due to its high ecological importance, the Ebro Delta was declared a nature park in 1983 and was recently even declared a biosphere reserve. The park has an area of 7,802 hectares and occupies the northern coast of the Baix Ebre district and the southern coast of the Montsiá district. Rice fields cover most of the delta. This created a perfect area for a distinctive fauna, especially birds. The delta offers a refuge for more than 300 species and numerous breeding colonies - a perfect stopover for migratory birds. The extensive plain has many lagoons, lakes and ponds. The coast is characterized by long, untouched beaches with sand dunes. Two large dune walls try to protect the bays “Fangar” in the north and “Alfacs” in the south.

Sights of the nature park:

• Canal Vell Lagoon: Large pond, refuge and nesting place for many species of birds, especially wild ducks. Bird watching. Access via the observation tower.
• The Ebro Estuary: Without a doubt, the most interesting place to observe the contrasts of the river's fresh water entering the Mediterranean. Only accessible by boat.
• Isla de San Antonio: Natural landscapes of sand dunes with a variety of vegetation. Waterfowl live here. Seen by boat on the way to the river mouth.
• Muntell de las Vírgenes: sand dune approx. 5 m high. It represents the highest natural point of the delta. Located on the left bank of the river, close to the mouth. Panoramic view of Isla de Buda.
• Garxal Lagoon: Unit of small islets and lagoons. A variety of water birds can be admired here. Signposted circular routes on foot or by bike (approx. 2.5 km), with information boards. Viewing platform with a wide view.
• Puente de los Moros: The Royal Bridge, also known as the Moors' Bridge, is located about 4 km from Deltebre in the direction of Riumar. It is a Roman-style arched bridge made of carved stone and filled with mortar. Despite its simple construction, this bridge is architecturally valuable as there are no comparable structures in this area. It is also the only remaining building of the ancestors and therefore an important symbol of the inhabitants of Deltebre. There is a picnic area next to the bridge.
• Punta del Fangar: A 140-hectare peninsula; an important breeding area for arctic terns and sandpipers; formations of fixed and shifting dunes; Mirages (Fata Morganas) on sunny days; mussel beds in the interior of the bay; observation tower with information board; bird watching; Access on foot or by bike via Playa de la Marquesa, along the sandy track between dunes and rice fields.
• Playa de la Marquesa: untouched, wide and very quiet beach.
