The Costanera Sky is located on 61st and 62nd floors of the Great Tower of Santiago at 253 and 261 meters high respectively. It was inaugurated on August 11, 2015 and has a glass platform to observe on the 61st floor and open sky on the 62nd, allowing the public to have a 360° view of Santiago on the building terrace. Visitors must purchase an access ticket, that will allow them to observe both viewpoints, which have binoculars near the windows to observe the city thoroughly. On cloudless days you can see up to 50 kilometers around, that is, from end to end of the city (including planes taking off from the Arturo Merino Benítez International Airport). It is the highest viewpoint in South America.
