Navimag

"A spectacular cruise through the forest-fringed fjords strung between northern and southern Patagonia, the Navimag ferry voyage from Puerto Natales to the city of Puerto Montt (or vice versa) is, for many travelers, one of the highlights of their trip to Chile. On a four-day, three-night journey, the ship travels through the glorious Parque Nacional Bernardo O'Higgins, immersing you in a remote, largely inaccessible realm studded with giant glaciers. It is also excellent for wildlife-watching. Whales, penguins, dolphins and albatrosses are among the species you are likely to spot en route."
