• Best Park Walks: The Palermo park system in Buenos Aires is one of the world's most beautiful. Within the system are numerous parks, such as the Rose Garden and the Japanese Garden, as well as museums such as the Museo de Arte Latinoamericano de Buenos Aires (Malba) and the Museo Nacional de Bellas Artes.
  • Getting Wet Beneath Iguazú Falls: Take an exhilarating boat ride beneath the plummeting waterfalls. A number of tour companies operate rafts that speed toward the falls, soaking their awe-struck passengers along the way. This is the best way to experience the sound and fury of Iguazú's magnificent cataratas.
  • Traveling Beyond the Falls into the Iguazú Jungle: This is a place where such birds as the great dusky swift and brilliant morpho butterflies spread color through the thick forest canopy. You can easily arrange an outing into the forest once you arrive in Iguazú.
  • Paragliding in La Cumbre: Jumping off a 300m (984-ft.) cliff and flying with condors is what attracts world-champion paragliders to this laid-back valley in the Córdoba sierra.
  • Bird-watching in Esteros del Ibera: The flat marshlands of Corrientes province are a nature lover's paradise and can be explored by boat or horseback.
  • Raging Down the Mendoza River: Mendoza offers the best white-water rafting in Argentina. During the summer months, when the snow melts in the Andes and fills the Mendoza River, rafters take on Class IV and V rapids here. Rafting is possible year-round, but the river is colder and calmer in winter months.
  • Skiing Las Leñas: One of South America's top ski destinations, Las Leñas boasts more slopes than any single resort in the Americas, with 40 miles of runs, excellent snow, and typically small crowds. Las Leñas also hosts an active nightlife in winter.
  • Skiing Cerro Catedral: With a huge investment in new lifts, new development at the base, and consecutive years of heavy snowfall, Bariloche's Catedral is the best ski resort in Argentina. The après-ski scene includes chocolate shops, live music, and happening slopeside lounges. And the views take in the Andes and the beautiful Nahuel Huapi Lake.
  • Rafting the Río Manso: There are two sections to this gorgeous emerald river south of Bariloche. The Inferior makes for a great family outing, with bird-watching and fun paddling. The Frontera section takes you through an adrenaline-heavy set of 10 rapids toward the border with Chile. Either way, it's a trip through a beautiful undiscovered mountain valley.
  • Fly-Fishing in Patagonia: Few places in the world are as appealing to expert fly-fishers, and as rewarding to beginners and novices, as Argentina's Patagonia. Remote rivers from Junín de los Andes all the way down to Tierra del Fuego draw fanatics who long for solitude, gorgeous scenery and, of course, very big trout. Great guides become lifelong friends.
  • Lahuen Co Hot Springs: If your idea of the outdoors includes gentle pampering and peace and quiet, this remote thermal spa deep in Lanín National Park will wow you. Small, natural pools (indoor and out) are heated by natural thermal waters in a volcanic area in the middle of a temperate rainforest outside San Martín de los Andes.
  • Horseback Riding the Patagonian Steppe: Discover your inner gaucho on a horseback ride across a beautiful horizon on the wild steppe or into the deep Andes. Horses are cherished here, lovingly cared for by dedicated gauchos.
  • Hiking to Laguna Torre: One of the world's finest day hikes takes you from the door of your inn in El Chaltén to the base of the needle-shaped granite spire of Cerro Torre, a legendary challenge for mountaineers and rock climbers. The hike's pinnacle is on the shores of the blustery Laguna Torre, where the wind feels like it just may blow you over. Back in the shelter of the FitzRoy River valley, you'll head back to town refreshed and exhilarated.
  • Big Ice: Hiking in Perito Moreno Glacier: Tour operators have been offering guided walks on the Perito Moreno Glacier for years, and guests from around the world strap on some crampons and head out for an hour or so. Those with a good level of fitness can now head much deeper into the glacier with a full-day hike. Peer into deep ice canyons, navigate your way along a frozen ridge, and try to grasp the sheer grandeur of this UNESCO World Heritage Site.
