sky100 Hong Kong Observation Deck (sky100) is turning 10 this year! To thank everyone for their exceptional support over the last decade, from now until 30 June 2021, sky100 is launching the Hong Kong resident exclusive "Extraordinary Birthday Offers" to kick off a series of celebrations, inviting everyone to soar to 393 metres above sea level at the city’s tallest building and share the birthday joy with their loved ones at sky100.
