You can complete your visit to Sky Costanera in anywhere between 60-90 minutes, if your goal is to ride the high-speed elevators to the observation deck, soak in the views, and make our way down.
However, if you plan on catching the sunset, you will need to arrive at least 45 minutes before time to secure a spot right up front. Additionally, post sunset, you’ll also get to see the city’s skyline transform, from the warm dusky glow of the sun to the city lighting up all around you. Capturing these views, along with dining or spending some time shopping, can take you anywhere between 2-3 hours.
