Your 24-hour guide to the world

Where best to be every hour of the day to catch the planet's top sights and experiences - even if you'll need a teletransporter to make it happen.

12 midnight: Kilimanjaro, Tanzania

Steel yourself: this is the time to start your gruelling summit attempt on the 5,895m mountain. With any luck youʼll be up there by sunrise...

1am: New York, USA

Head up the Empire State Building. Its observation deck is open until 2am – the ultimate place to survey the city that never sleeps.

2am: Lausanne, Switzerland

Listen for the last cry of the nightwatchman – since 1405 a guardian has called from the Cathedral's belfry every hour, on the hour, from 10pm to 2am: 'C'est le guet; il a sonné lʼheure' ('This is the nightwatch; the hour has struck').

3am: London, England

Join the early-rising meat traders of 140-year-old Smithfield Market – though youʼll have to wait until 6am for the nearby Hope pub to open.

Grab an early breakfast at Fran's. This atmospheric diner has been serving favourites such as prize-winning pancakes and baby rack ribs 24 hours a day since 1940.

Wrap up warm for the El Tatio Geysers. These high-altitude geothermal gurglings are most spectacular at sunrise, when their steam condenses in the cold air.

6am: Mumbai, India

Flex your chuckle-muscles at a Laughter Yoga session on Chowpatty Beach, where lighthearted locals gather for a therapeutic giggle.

Prepare for the pomp and parading that accompanies the daily flag-raising in the capital's super-sized Zócalo square.

Join a free guided tour to better appreciate the elegant Sheikh Zayid Grand Mosque, one of the largest in the world.

Walk into the colossal cathedral – the goal for every peregrino making the epic Camino de Santiago pilgrimage – for the special Pilgrim's Mass, held daily at noon.

1pm: Edinburgh, Scotland

Cover your ears for the Castle's One oʼclock Gun, which has been fired from the battlements almost daily since 1861. Not open Sundays.

Watch as the resident mallards of the Peabody Hotel are led from the foyer fountain, along a red carpet, to their penthouse home.
