Península Valdés
Chubut
Valdés Peninsula, located in northeast Chubut Province, Argentina, is a vast natural reserve recognized as a UNESCO World Heritage Site since 1999. Covering approximately 3,625 km², it is a prominent coastal landform extending into the Atlantic Ocean and bordered by the San Matías Gulf. The peninsula's landscape features barren lands interspersed with salt lakes, some lying below sea level. It is famous for its rich marine biodiversity, including breeding grounds for southern right whales in the protected waters of Golfo Nuevo and Golfo San José. Visitors can observe marine mammals such as sea lions, elephant seals, fur seals, and orcas, which uniquely beach themselves to hunt. Inland, the peninsula supports terrestrial fauna like rheas, guanacos, and maras, alongside a diverse bird population with over 180 species, including significant colonies of Magellanic penguins. The climate is typical of northern Patagonia, characterized by cold desert and semi-desert conditions, with moderate temperatures and low but variable precipitation influenced by the El Niño Southern Oscillation. The small settlement of Puerto Pirámides serves as the main gateway for whale watching and nature tourism. The peninsula's unique combination of geological features, diverse ecosystems, and abundant wildlife make it an exceptional destination for nature lovers and eco-tourists.

Relations between indigenous peoples and Spanish colonists were initially peaceful but later deteriorated, leading to the destruction of the settlement around 1810.
Permanent Argentine colonization began in the mid-19th century.
Between 1901 and 1920, a railway operated to exploit salt deposits.
