This small island is situated close to Carlos Ameghino isthmus shore (that gathers Península Valdés with the continent) on San José Gulf.
Birds reproductive area
This place has a great biological value since it’s used as reproductive area for many sea and shore specimens such as: kelp gulls, rock shags, neotropic cormorants, Eurasian oystercatchers, great egrets, black-crowned night herons, fuegian steamer ducks, crested duck and Magellanic penguins. It is also possible to watch flamingos, arctic terns and brown-hooded gulls, depending on the season.
Is it in fact an island?
This “Island” is in fact a tombolo, a piece of plateau that at low tide is attached to the continent. During this period, which lasts for about 12 hours, the “island” is connected to the mainland and it shows up part of its marine life (crabs, seaweed, etc.). In this moment, it is possible to go across the route that gathers the island to the continent for about 2 hours without even drenching your ankles.
Even though it is forbidden to get in the island for being an intangible region, visitors may enjoy the viewpoint located on the shore, from where it’s possible to appreciate the view of the island and the diversity of birds in full activity. Besides, there’re rangers who provide information about fauna and flora of the area.
