At 800 metres long, the Central–Mid-Levels Escalator is the world's longest covered outdoor escalator. It links Des Voeux Road Central near the harbour to Conduit Road in the Mid-Levels. Travelling its entire length takes around 20 minutes and it's a convenient and fun way to check out the bustling city hillside which contains great restaurants and shops. The escalator runs one-way downhill from 6–10am and then changes to uphill from 10am to midnight. As it's used as a transport link for many Mid-Levels residents in the mornings, it's best to avoid it until after 9am when the morning rush hour is over.
