Located in the Punta Norte area on the Peninsula Valdes, the sheep ranch San Lorenzo occupies 5,134 hectares and stretches 5,300 metres along the coast of the San Matias Gulf. This is one of the few places in Argentina where the sun can be seen to set over the sea.
The Ranch is part of the Protected Natural Area Peninsula Valdes, UNESCO World Heritage Site, under the designation PROTECTED AREA SAN LORENZO RANCH, the first ranch on the peninsula to be granted such categorization.
San Lorenzo gives shelter to a Magellanic penguin rookery of around 500.000 individuals that arrive here every year to breed and moult. In 1999 when the tourism activity started, 123 hectares were set apart for the Magellanic penguins only. To that end, the area was fenced and the sheep were removed, thus creating the right environment for the penguins in the wild.
This traditional Patagonian sheep ranch raises Australian merino sheep for wool production. As from September, visitors can witness the different activities related to sheep farming: marking, shearing, and sheep enclosure with the help of the herding dogs.
The shearing barn was reconditioned to serve as a country restaurant, visitor centre and mini shop for local products and ranch souvenirs.
An additional interest for tourism are the marine fossils that crop out in the cliffs and gullies that run down to the sea. Many of these fossils can be observed in the Gulley of Fossils.
Visitors can also see the ruins of the old sea lion factory as between 1917 and 1953 commercial killings of sea lions took place at San Lorenzo for their blubber and skin.
