World's largest swimming pool is the size of 11 football pitches and looks VERY inviting

As temperatures in the UK continue to climb, imagine cooling off in the largest swimming pool in the world.

You'll have to catch a flight to Chile in order to experience the pool at the San Alfonso del Mar resort - but once you're there you can indulge in kayaking, wind surfing and even SCUBA diving. No underwater tennis, though.

The pool measures 1,013m (3,323ft) long and, at its maximum depth, reaches 3.5m (11.5ft).

The total size of the giant tank is an amazing 19.77 acres, the size of 11 football pitches. It's enough to unquestionably earn it the Guinness World Record for Earth's largest swimming pool.

It was built by Fernando Fischmann, chairman and founder of Crystal Lagoons. The entire construction took five years and cost £2million.

Fischmann, who started out as a biochemist, developed a computer-controlled suction and filtration system that collects and filters water from the ocean before pumping it into the massive pool.

The technology carries a worldwide patent and the sun's energy heats the water up to a comfortable 26C - nine degrees higher than the surrounding sea.

The result is a hugely popular tourist destination not only for international visitors but Chileans themselves. After all, who doesn't want to sail a boat on a swimming pool?

If you fancied swimming a length of the pool, you're looking at covering three fifths of a mile. Which is basically 20 Olympic-size swimming pools laid end-to-end

But, as the temperatures in the UK are set to reach their hottest levels in nine yearstoday, San Alfonso del Mar certainly looks inviting.
