Dubai sets a world record:

Dubai is already home to the world’s tallest building. Now it can lay claim to the world’s deepest diving pool too.

The new indoor pool is nearly 200 feet deep and holds almost 3.7 million gallons of water. It’s also home to a vast underwater attraction resembling a “sunken city” that divers can explore either on their own or with a guide.

The attraction is open to travelers aged 10 and older, including those who are donning a mask and tank for the first time.

‘Sunken city’

With graffiti, crumbling facades and a large portrait of Marilyn Monroe hanging on the wall, Dubai’s new vertical diving pool contains the remnants of a lost submerged city.

Beginners can dive to a depth of 40 feet, while those with certifications can explore the entire pool either with a guide or alone. Certified divers can also “free dive” — which is diving without a tank, using breath only — while connected to a fixed ascent line.

Diving in a pool has several benefits over the ocean. For starters, weather and water conditions are controlled. There are no currents or rough seas, and dives aren’t canceled due to bad weather.

Pool water can be well-lit, even at lower depths. Dubai’s new pool has 156 lights positioned throughout the pool and water temperatures are maintained at a comfortable 86 degrees Fahrenheit.

There is, however, no living marine life, including coral, which is normally a huge part of the leisure diving experience.
