Nestled along the Gulf of Oristano in the municipality of Arborea, the S'Ena Arrubia Lagoon (Stagno di S'Ena Arrubia) stands as one of Italy's most ecologically valuable wetlands, protected as a nature reserve and Special Protection Area. A remnant of the vast, ancient Lake Santa Giusta, this brackish basin gets its name—meaning "reddish vein"—from the reddish hue its waters once took on due to iron-rich sediments washed down by nearby channels.
Today, the lagoon is a true wildlife sanctuary and a must-visit destination for birdwatching. Among the dense reed beds and lush riparian vegetation, over a hundred bird species find refuge and nesting grounds—most notably majestic pink flamingos, western swamphens with their vibrant blue plumage, purple and gray herons, marsh harriers, and grebes. Its waters are equally teeming with aquatic life, historically sustained by local artisanal fishing practices.
A visit to S'Ena Arrubia offers a wonderful stepping stone for discovering the unique character of this corner of Sardinia. Just a short drive away lies the town of Arborea, famous for its distinctive 1930s Rationalist architecture and thriving agricultural tradition, while along the coast stretch the broad golden sands of Arborea's beaches and the fragrant pine forest of Marina di Torre Grande.
