Your day trip starts with pickup from select districts of Santiago for the drive north of the city toward Ski Portillo. Travel for roughly two hours along the route known as Los Conquistadores, passing through valleys until you reach your first stop, the Monument of the Victory of Chacabuco.
Enjoy a photo op, and then continue to the Aconcagua Valley winery selected when booking, either Viña San Esteban or Viña Errazuriz. Each features picturesque scenery, which you can enjoy on a tour of the main facility. Then enjoy a wine tasting of select varietals.
Back in the tour vehicle, head on to Ski Portillo, catching a glimpse of the ski resort's mascot, a St. Bernard who welcomes you upon arrival. At this point, your free time begins to spend however you wish. Take in views of Portillo Inca Lagoon, surrounded by mountains, or hop on the ski lift to catch a few runs or enjoy lunch (any activities and food are at your own expense).
In the late afternoon, you'll start the drive back to Santiago for drop-off at your hotel or central location.
