The story of a place

An Atlantic peninsula whose wildlife calendar shapes the journey.

Península Valdés is a broad, dry landscape with a remarkably rich marine edge. Whales, seals, sea lions and penguins use different places and seasons, so no single visit represents everything the peninsula offers.

Choose the wildlife encounter that matters most, then build the itinerary around its timing and responsible viewing arrangements. Dramatic hunting behaviour seen in films is rare and never guaranteed.
