The Guadalquivir Marshes are the largest wetland in Spain and one of the most important in Europe, a biodiversity sanctuary that hosts more than six million birds during migrations.
At THE SUN PLACES we know that some experiences deserve to be lived calmly and with maximum comfort. That is why we invite you to discover the Guadalquivir Marshes from the comfort of our Luxury Apartments in Seville, also with a presence in Cádiz, Puerto Banús and Sanlúcar de Barrameda. Because the Guadalquivir Marshes are not just a natural destination, they are an immersion in the wildest and most authentic essence of Andalusia.
What are the Guadalquivir Marshes?
🌊 Geological formation: From the Tartessian Gulf to the most important wetland in Europe
To understand the Guadalquivir Marshes we must travel back thousands of years. 5,000 years ago, this entire area was submerged under a vast sea. Little by little, the Atlantic current formed a coastal dune which, with the south-westerly winds, reached Sanlúcar de Barrameda, creating a lake that the Romans called Lacus Ligustinus.
The sediments carried by the Guadalquivir into the sea over centuries gradually filled that lake, which stretched from the Atlantic to Seville, creating a huge marsh of about 2,000 km² (about 200,000 hectares). This territory, located between the provinces of Seville, Huelva and Cádiz, is today one of the most extensive and best-known wetlands in Europe.
In the province of Seville, the Guadalquivir Marshes cover municipalities such as Aznalcázar, Las Cabezas de San Juan, Dos Hermanas, Lebrija, Isla Mayor, Los Palacios y Villafranca, La Puebla del Río and Utrera. In Cádiz, they reach Trebujena and Sanlúcar de Barrameda; and in Huelva, Almonte and Hinojos.
The landscape is characterised by its extreme horizontality. During rainy periods, the marsh becomes an immense lake area due to its flat shape, its proximity to sea level and the impermeable nature of its subsoil, which acts as a practically sealed raft. In summer, on the other hand, the water evaporates and the earth cracks, showing its most inhospitable side.
What is the History of the Guadalquivir Marshes?
📜 History: An untamed land that resisted until the 20th century
The history of the Guadalquivir Marshes is the story of the struggle between man and nature. Since historical times, these lands have been seen as a space to be subdued, but they resisted until well into the 20th century as one of the last places of untamed nature in Europe.
The saline soils, winter flooding and summer drought made them an uninhabitable place for humans, but a paradise for wildlife. As early as the 9th century, the Arabs practised horse breeding for military purposes on the islands of the Guadalquivir, famous for their always green meadows, and tried the first rice crops, which failed due to the force of the tide.
In 1253, King Alfonso X granted the Isla Mayor to the Council of Seville. Since then, the "grasses of the Islands", the ashes of the saltworts to make soap and the fisheries were exploited. In the 15th century, the Catholic Monarchs leased these lands to help pay the costs of the conquest of the Kingdom of Granada.
For centuries, the extensive, bare marsh plains were pasture for the livestock of the riverside towns and even for livestock from Extremadura. On the vetas (slightly higher ground), huts and camps of shepherds, cowherds and labourers began to appear, the first human settlements in a territory that remained almost natural until the end of the 19th century.
It was from then on that the great transformation began: the draining of the marshes to turn them into farmland, a process that would culminate in the 20th century with the colonisation of the area by Valencian rice growers and the creation of Isla Mayor, the rice heart of Seville.
🦩Biodiversity of the Guadalquivir Marshes
The paradise of birds
If there is one thing that makes the Guadalquivir Marshes a unique place in the world, it is its biological richness. This area is the most important wetland in Spain for breeding, passage and wintering of waterbirds and passerines.
🐦 A sanctuary for millions of birds
More than 360 species of birds have been recorded in the area. The figures are astonishing: during winter, waterbird populations reach 400,000 birds, and during migration periods, this figure soars to over six million birds. In fact, in recent censuses, the total estimated number of wintering birds in the Doñana Natural Area was 674,974 birds of 103 different species, the highest number in the last 15 years.
Among the most emblematic species that inhabit the Guadalquivir Marshes are the greylag goose, the great bittern, the red knot, the common snipe, the red-crested pochard, the Eurasian spoonbill, the black kite, the lesser black-backed gull, the common magpie and the common starling. During migrations, thousands of geese travel up to three thousand kilometres from northern Europe to winter in these warm lands.
🐾 Beyond the birds
- The Guadalquivir Marshes are not only a paradise for birds. Doñana National Park, integrated into the marsh system, is home to unique and seriously endangered species, such as the Spanish imperial eagle and the Iberian lynx.
- The ecosystem is a mosaic of habitats: beach, dunes, Mediterranean scrubland areas (with rockrose and cistus), pine forests, cork oak forests and, of course, the marsh itself with its halophytic vegetation of saltwort, castañuela and bayunco.
🍚 Rice cultivation: The human transformation of the marsh
The current reality of the Guadalquivir Marshes cannot be understood without talking about rice. Today, the province of Seville is the largest rice producer in Spain, with around 36,500 hectares under cultivation, which represents approximately 45% of national production.
80% of the rice-growing area in the province of Seville lies within the boundaries considered to be the immediate surroundings of the Doñana National Park, forming an essential part of its ecosystem. The Guadalquivir Marshes contain the largest area in Spain dedicated to rice cultivation and are one of the most productive areas in Europe.

🗺️ Tourism: How to discover the Guadalquivir Marshes
- The Guadalquivir Marshes are a top-level ecotourism destination. There are many ways to explore them and connect with their wild nature.
🚐 4×4 routes
- One of the most recommended experiences are guided 4×4 routes. These excursions usually depart from Sanlúcar or Jerez and travel along roads that in rainy seasons become marshes, with stops at vineyards of the Jerez region (such as Carrascal and Macharnudo) and at archaeological sites such as Asta Regia, an ancient possibly Tartessian city inhabited until the 10th century AD. Specialised guides provide binoculars and reference material for bird watching. Upon your arrival, a good Manzanilla de La Gitana and the Bajo Guía Restaurants in Sanlúcar de Barrameda await you.
🚴 Hiking and cycling
- The Guadalquivir region offers different routes to explore the area on foot, by bike or on horseback. The Guadalquivir River Greenway allows you to enter the marshes via historic paths. There are also circular routes starting from towns such as Coria del Río, just 16 km from Seville, covering the most varied and rich landscapes of the Seville area.
🚤 River navigation
- Boat Rides on the Guadalquivir are an activity offered by towns such as Gelves and Coria del Río. There is also a small ferry with which to cross the river while enjoying a 5-minute mini cruise, a unique way to disconnect from the hustle and bustle of the big city.
🚵 By motorbike
- For motorcycle lovers, riding through the Guadalquivir Marshes is an unforgettable experience. The roads that border the river offer open landscapes and a feeling of absolute freedom.
🎣 Fishing and gastronomy
- The Guadalquivir offers fish such as albur, carp and other species. Sunsets on the riverbank are dreamy, and the rice fields produce the best rice in Spain. The region is integrated into the Seville Rice Route, an opportunity to taste exquisite dishes made with this marsh product.
✨What do the Guadalquivir Marshes represent?
The Guadalquivir Marshes are much more than a natural space. They are the green heart of Andalusia, a territory where nature still imposes itself and where human beings have learned to live with the cycles of water and life.
- For Seville, the marshes are the natural lung that protects the coast, the filter that purifies the water and the refuge of species unique in the world. For Andalusia, they are a symbol of the natural wealth of this land and a top-level tourist attraction. For Spain, they are the most important wetland in the country and a jewel of European natural heritage.
