Cross the Strait of Magellan to Isla Magdalena and Isla Marta. Together, these islands form the Los Pinguinos National Monument, which protects more than 120,000 penguins as well as a small colony of sea lions. The islands form an interesting ecosystem - Marta Island is home to more than 1,000 sea lions, along with cormorants, skuas, the Austral seagull, Antarctic pigeon and sea elephants. You can't step ashore on Marta due to local regulations, so you will circumnavigate the island to admire and photograph both the colony and the diversity of marine birds that live there. On Magdalena Island, you will go ashore and interact with one of the major colonies of Magellan penguins - more than 150,000 birds - spending an hour walking among colony.
