Head from Puerto Madryn across the Ameghino isthmus that marks the start of the National Park of Peninsula Valdes, A UNESCO World Heritage Site. Arrive at Caleta Valdes, a natural creek embraced by a long promontory, home to a colony of sea elephants who grunt and roar at each other on the sands. The surrounding rocks and dry grasses are also the natural habitat for storks, guanaco deer, armadillos, Patagonian hares, foxes, eagles and many others. Then head further out on the Peninsula to the far shores of Punta Norte, also the habitat of huge colonies of marine mammals. In breeding season Feb-Apr, the Orcas have been known to target the sealion pups, almost beaching themselves to hunt for them. Visit the Magellanic Penguin Colony at Estancia San Lorenzo which is much less visited than Punta Tombo.
