The pool in question is called “The Mountain” and it cost US$2 million (NZ$3.17 million) to construct.
This man-made aquatic paradise in Springville, Utah, has a grand total of five waterfalls.
Here you can not only swim and jump off the mountain top (with a backflip, if you’re game) but you can also scuba dive, scoot down a water slide or cook a quality meal for your pals.
The hidden water slide measures 18 metres long and winds through the inside of the mountain before it spits you out through one of the waterfalls.
Inside the mountain, among the spiderweb of secret tunnels, is a kitchen with granite benchtops, an eight-burner grill and a mini fridge.
