Dubai unveils world’s deepest pool creating Guinness World Record, experience underwater city

High profile guests including actor Will Smith and Dubai crown prince Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum have already visited the pool.

Sheikh Hamadan encouraged others to visit when it the complex opens to the public later this month, writing on social media after his July 7 visit: 'An entire world awaits you at Deep Dive Dubai, the world's deepest pool'.

Smith described the experience as 'madness' and he said he was told to check out the pool by a friend because it has 'something... weird about it'.

But Deep Dive has warned guests not to visit the Burj Khalifa - the world's tallest building, also located in Dubai - after their visit.

'Don't visit the top of the skyscraper after diving,' it says.
