Antilco, a horseback-riding center, leads treks with a maximum eight riders at a time over the Andes and all the way into Argentina. Participants cross the mountain range astride sure-footed criollo horses in the company of guides, setting out from Pucón and riding upward, and eastward, for days. There are pauses for dips in mountain lakes or to simply take in the sierra’s beauty, and tours include cookouts prepared by aides, who also handle all the “cowboy” chores, and nightly campfires. You don’t need to be an expert rider on this adventure, but you do need to be ready for an average of eight hours a day in the saddle. The trip ends in Las Lajas, where a private bus takes riders back to Chile. Other Antilco tours on horseback include the Lake District, Torres del Paine National Park, and Easter Island.
