The Ebro Delta stretches across the counties of Baix Ebre and Montsià along the Costa Dorada in Tarragona, Catalonia, Spain. At its tip is the mouth of the Ebro, Spain’s most water-rich river, which has shaped the delta over centuries. Due to its significant ecological value, the Ebro Delta was designated a natural park in 1983 and recently declared a biosphere reserve. The park covers an area of 7,802 hectares, spanning the northern coast of Baix Ebre and the southern coast of Montsià.

The delta is predominantly covered by rice fields, creating an ideal environment for a diverse fauna, particularly birds. The delta provides refuge for over 300 species and numerous breeding colonies, making it a perfect stopover for migratory birds. The expansive plain features numerous lagoons, lakes, and ponds, while the coastline is characterized by long, pristine beaches and sand dunes, protected by two large dune barriers that shield the “Fangar” bay to the north and the “Alfacs” bay to the south.

Highlights of the Nature Park:

• Laguna Canal Vell: A large pond that serves as a sanctuary and nesting site for many bird species, particularly wild ducks. An observation tower provides excellent birdwatching opportunities.

• The Ebro River Mouth: Undoubtedly the most interesting spot to observe the contrast between the river’s fresh water and the Mediterranean Sea. Accessible only by boat.

• Isla de San Antonio: A natural landscape of sand dunes with diverse vegetation, home to water birds. The island can be seen from a boat on the way to the river mouth.

• Muntell de las Vírgenes: A sand dune about 5 meters high, the highest natural point of the delta. Located on the left bank of the river near the mouth, it offers panoramic views of Isla de Buda.

• Laguna Garxal: A collection of small islets and lagoons where a variety of water birds can be observed. Marked trails for walking or cycling (approx. 2.5 km) lead to a viewpoint with a wide view.

• Puente de los Moros: Also known as the King’s Bridge or Moorish Bridge, located about 4 km from Deltebre towards Riumar. This Roman-style arch bridge made of carved stone is architecturally valuable and is the only remaining structure from ancient times, making it an important symbol for the people of Deltebre. There is also a picnic area next to the bridge.

• Punta del Fangar: A 140-hectare peninsula; a key area for nesting sites of coastal terns and sandpipers; features both fixed and shifting dunes; on sunny days, mirages (Fata Morganas); shell banks within the bay; an observation tower with an information board; opportunities for birdwatching; accessible on foot or by bike via Playa de la Marquesa, along the sandy track between dunes and rice fields.

• Playa de la Marquesa: A pristine, wide, and very tranquil beach, perfect for relaxation and enjoying peaceful moments by the sea.
