Fodor's Expert Review Cerro Torre and Cerro Fitzroy
You don't need a guide to do the classic treks to Cerro Torre and Cerro Fitzroy, each about six to eight hours round-trip out of El Chaltén. If your legs feel up to it the day you do the Fitzroy walk, tack on an hour of steep switchbacks to Mirador Tres Lagos, the lookout with the best views of Mt. Fitzroy and its glacial lakes. Both routes, plus the Mirador and various side trails, can be combined in a two- or three-day trip.
