Skiing in the Lake Districts and Volcanoes in Chile, this is well explained in the links above.
For hiking and trekking in Fitz Roy area and Torres del Paine, come early december (less people) avoid January
For climbing moderate alpine, best Refugio Frey, Cochamo, Cerro Lopez.
For climbing the big leagues , get to Chalten, and you have the Fitz roy range
Kayak, rafting and soft adventures, Bariloche is the best spot. But is pioneering and developing well in southern patagonia
Wild travel destinations
Cerro Castillo, excellent to find the solitude that Southern Patagonia had once. Smaller peaks but very wild
Travel agencies patagonia argentina
Look for certified guides, check this explanation here
Biking, cycling and mountain bike trips
Many options! very scenic to travel through lake districts, check the volcanoes in chile, the ocean, the northern patagonia lakes and mountains.
For long trips road 40 is wild and very very windy!
Ushuaia is very nice for doing a multiday bike tour, but best area I would say is Lake districts, volcan llaima, lonquimay, osorno, villarica. Pucon town, Bariloche, San Martin de los Andes and Seven Lakes tour.
