Although there are a number of boat tours through the Canal Beagle or around the bays to Tierra del Fuego National Park, one offers an experience that will put you in the shoes of the earliest explorers to visit the far south. The operators of Tres Marias Excursions offer a half-day sailing trip to Island H, an outcrop in the middle of the channel, with cormorant colonies, families of snow geese, seaweed stands, and a weather station that records the howling winds blowing in from the misnamed Pacific Ocean. The guides are skillful sailors and storytellers. On a gusty day you'll marvel at the hardiness of the Yamana people, who survived frigid winters wearing little or no clothing by setting fires behind natural and manmade windbreaks. You'll find the same plant and moss species that grow in the high Andes; they thrive here at sea level because the conditions kill off less hardy, temperate species. On the way back you visit a sea lion colony, but won't soon forget arriving in Ushuaia under full sail as the late sun hits the mountains. At $60USD it's only a little more expensive, and a lot more adventurous, than the motorized alternatives trawling for business at the dock. Tours only October to March.
