Hielo y Aventura's conventional cruise Safari Nautico (AR$500, one hour) tours Brazo Rico, Lago Argentino and the south side of Canal de los Témpanos. Catamarans crammed with up to 130 passengers leave hourly between 10:30am and 4:30pm from Puerto Bajo de las Sombras. During busy periods buy tickets in advance for afternoon departures.
To hike on Glaciar Perito Moreno, try mini-trekking (AR$2700, under two hours on ice), or the longer and more demanding Big Ice (AR$5200, four hours on ice). Both involve a quick boat ride from Puerto Bajo de las Sombras, a walk through lenga forests, a chat on glaciology and then an ice walk using crampons. Children under eight are not allowed; reserve ahead and bring your own food. Don’t forget rain gear: it’s often snowing around the glacier and you might quickly become wet and cold on the boat deck. Transfers cost extra (AR$1000).
