The water in these jacuzzis must be so pure

Welcome to Mexico's Las Grutas de Tolantongo resort, where you'll find a jacuzzi with a difference.

Warm thermal water rushes into the valley, creating a series of beautiful swimming pools.

The water is full of mineral salts that help bathers relax and de-stress.

It's unlikely you'll find a better pool on the planet.

Take a look at the video above for a taster.
