Mountain Climbing

Casa de Guias. A guide is required if you want to enter the ice field or trek on any of the glaciers in Los Glaciares National Park. Casa de Guias is a group of professional, multilingual guides who offer fully equipped multiday treks covering all the classic routes in the national park, and longer trips exploring the ice field. They even offer a taste of big-wall climbing on one of the spires in the Fitzroy range. Av. San Martin 310, El Chaltén, Santa Cruz, 9301. 2962/493–118; www.casadeguias.com.ar.
