Dress warmly with trekking boots and a packed lunch. Meet your guide in your hotel lobby for convenient transportation to the Bajo de las Sombras port for a boat ride to the glacier. Once you arrive, get kitted out with all the glacier-hiking equipment you would need: crampons, ice axes, and the like. Your guides will fill you in on the safety considerations and general methods for safe glacier hiking before you take off.
Follow your leaders along the Rico Arm for a 90-minute trek across Perito Moreno, accompanied by engaging commentary on the formation and history of the glacier. At the end of the hike, find a scenic spot for a packed-lunch picnic and then continue through the forest to the spot where your bus will pick you up. The day's last stop is at the best lookout point for views and photos of the glacier you just conquered before heading back to your El Calafate hotel.
