The Isla de Lobos is a small island located about 8 kilometres (5.0 mi) southeast of Punta del Este (Uruguay). An islet lies east of the island.


The island is an outcropping of rocks that is a continuation of the Cuchilla Grande, in an area of Atlantic Ocean immediately at the mouth (outer limit) of the estuary of Río de la Plata. Administratively it belongs to the jurisdiction of the province of Maldonado, although it constitutes a natural reserve. Somewhat to the northwest is the smaller Gorriti Island which is the second most southern place in Uruguay.

Was exploited as a colony until 1992 when by law, protecting the ecology, since 1991 the slaughter and rookery exploitation of the island is prohibited.[1] Today constitute a nature reserve that integrates the "Coastal Islands National Park" administered by the Ministry of Livestock, Agriculture, and Fisheries.


It was discovered by Spanish navigator Juan Díaz de Solís in 1516 and named "San Sebastian de Cádiz", later in 1527 was visited by the Venetian navigator Sebastián Cabot in his expedition to Río de la Plata and Paraná. In 1528 Diego Garcia Moguer sailed for the region and named the "Island of the Snapper." In 1599 the island was visited by Laurens Bicker.[2]

In 1858 the Uruguayan government erected a lighthouse on the island, and rebuilt in 1906.[3] With its height of 59 meters above sea level [4] it is, in 2014, is the third tallest lighthouse in the world. From the balcony outside, which is accessed upon authorization by 240 steps there is a wonderful panoramic view of the island and the coast of Punta del Este.

In July 2001 he became the first automated lighthouse in Uruguay, with solar energy and high technology. It has a siren that runs on compressed air[5] as an alternative to the days of thick fog.[6]


Isla de Lobos is a nature reserve because it has the largest colony of sea lions in the western hemisphere: in 2005 there were 250,000 sea lions of the species called "two hairs" and 1,500 of the species known as the "wig".[7] Can also be found different types of orcas and birds.[8]
