Seno Otway is one of the traditional penguin excursions from Punta Arenas, known for a seasonal colony of Magellanic penguins on the shore northwest of the city. The appeal is simple and strong: birds moving between burrows, beach, and water in the hard Patagonian wind, with the strait country stretching open around them.
Access has changed over the years, and travellers should check locally before setting out rather than assuming the old visitor routine still applies. If visits are operating, go with patience and distance. The birds are the point, not a selfie with them, and the best moments are usually the quiet ones when the colony settles into its own rhythm.
