Known as Penguin Island, Isla Yecapasela is colonized by cute flocks of Magellanic and gentoo penguins.
A working nature reserve, the Yecapasela Reserve was created on the island (also known as Isla Martillo) and surrounding islets by Estancia Harberton in the 1970s.
The island was formerly home to the estancia's cattle and sheep, and since their removal in the 1960s the penguin numbers have soared. Sharing the islands with cormorants, the penguin colonies are flourishing in this safe environment. The breeding season begins in early October, and ends with the annual migration northwards in April.
From the shoreline you can spot black and white Magellanic penguins, shyer gentoos and possibly a visiting king penguin or two.
Penguin Island is on Isla Yecapasela at Estancia Harberton, 85km (52 miles) east of Ushuaia, 40 nautical miles by sea.
Tours sail from Ushuaia, sometimes continuing on to the estancia homestead.
A limited number of groups are permitted to walk with the penguins. Accompanied by a guide and following a designated trail, these specially regulated tours leave from Estancia Harberton’s homestead, 15 minutes from the island by boat.
