The Perito Moreno Glacier offers a spectacle of images and sounds, light icefalls occur permanently, so it is very possible to witness this particular phenomenon of nature. The uniqueness of the glacier lies not only in its 30 km length and its easy access, but also in the fact that it is one of the few that is advancing, while most of the world's glaciers are receding. The walkways, balconies and viewpoints installed in the national park allow even the elderly or people with some physical disability to approach the Perito Moreno without danger. The excursion concludes with the return to Puerto Natales by the same route.
