Musher-led sled rides and a guided snowshoe trek take you from the open Tierra Mayor basin into lenga forest to the Alvear Icefall. This winter-only outing pairs husky-powered speed with methodical snowshoeing and a warming refuge stop.
More ways to explore the area's outdoor wonders
A cold wind pushes across the Tierra Mayor valley as the sun drops low over lenga forest ridgelines. You meet the team at the trailhead outside Ushuaia, boots crunching in wind-packed snow while a pack of huskies strains at their lines—eager, focused, and ready to pull. The sled ride slices across the open basin, then the trail narrows into an old woodcutter’s road where trunks of lenga trees form a cathedral of pale bark.
