High in the Argentine Andes lies Las Lenas, the largest ski area in South America and the one with the continent’s biggest lift-served drop. Take the Marte lift and hike a short way to the top of the intermediate Apolo trail, which you can link up with the Neptuno and Venus trails for a 3,800-foot, treeless descent. If a heart-in-your-throat, barely-on-piste drop doesn’t scare you, take the Mercurio run for the full 3,900-foot experience.
