Set out from your El Calafate hotel with your packed lunch in the early morning. Board your coach for the journey to Los Glaciares National Park, listening to information about the adventure that lies ahead from your guide.
Arrive at Bajo Las Sombras harbor after two hours and board a boat for a 10-minute ride to Brazo Rico. Meet your local guide, who will issue your trekking equipment. Hike down the shore of Lago Argentino and through the forest along Brazo Rico to Perito Moreno's base.
Climb onto a viewing platform to get an awe-inspiring view of the 196-foot (60-meter) front wall of one of the world's only advancing glaciers. Listen to a safety briefing from your guide as you gaze out over the massive ice field. Put on your crampons and prepare to scale the glacier. Although this trek can be difficult, rest assured that with your guide leading the way, you can safely ascend the glacier's sloping surface.
Breathe the bracing air and learn about glaciology and geography from your guide. View waterfalls, lagoons, streams and caves formed by the constantly moving glacier's ice melt.
Pause to enjoy lunch at a scenic point, then retrace your steps to the glacier's edge, spending about 4 hours total on the ice. Return to the Rico Arm for the boat and bus journey back to El Calafate. Finish your day's adventure with drop-off at your hotel in El Calafate.
