This abandoned quarry which claimed the lives of cliff-jumping thrillseekers has now been turned into a water park.

The sprawling former limestone pit was previously known for causing deadly accidents with locals 'tombstoning' by leaping from the steep sides into the cold water.

The man-made canyon was originally quarried for soil, mine, and other natural materials before it was closed and naturally filled with water by monsoon rains.

It had stood deserted for more than a decade and was overrun with stray dogs, rubbish and filthy water.

But following a health and safety review makeover, the quarry is now one of the biggest inflatable water parks in Thailand with hundreds of tourists visiting every day.

It opened August 2016 as The Chiang Mai Grand Canyon water park offering fun outdoor activities.

Visitors now spend the whole day enjoying water activities including water sliding, canoeing, kayaking, zip-lining and wakeboarding.

Footage taken this week shows locals and tourists in swimming suits and life jackets climbing and jumping from the slippery inflatables in the floating aqua park.
