If you stay one night, and depending on the flight Schedule, you can take the navigation tour to Beagle Canal and visit Tierra del Fuego National Park. You would then need another day to take the excursion to Lakes Fagnano and Escondido. So, staying for three nights will give you enough time to take yet another alternative excursion in the area.
Alpine or mountain skiing is more widely known. It is practiced downhill and can take high speeds because of the inclination. Long straight skis are used for this sport, Alpine bindings attach at both the toe and the heel of the skier’s boots. Cross country skiing, part of the Nordic skiing family of sports, is practiced on valleys, in flat areas, using the legs and also the arms to move forward. Cross-country skiing is one of the most difficult endurance sports, as its motions use every major muscle group. The skis are long and thin, to distribute the weight of the skier and allow the skier to move quickly. The toe of the skier’s footwear is attached to the ski with a binding, while the heel remains free.
