You thought you had seen it all until now...
Aral Sea, Central Asia
Once one of the four largest lakes in the world, the Aral Sea is today an arid desert strewn with a handful of rusty old ships. The tragedy has been called one of the planet's worst environmental disasters.
Plitvice Lakes, Croatia
Plitvice Lakes National Park is one of the most beautiful places on earth and the lakes here are a true sight to behold. They are actually 16 lakes, all interconnected through a series of waterfalls and caves!
Laguna Colorada, Bolivia
This eerie lake in Bolivia has blood red water and is dotted with strange white islands made of borax, the same stuff used in many detergents!
Boiling Lake, Dominican Republic
Boiling Lake is the hottest natural spring in the world. Along its edges the water temperature is a sweltering 90°C! Nearly always shrouded in mist, it is always bubbling.
Lake Nyos, Cameroon
This lake in Cameroon is one of the world's only known exploding lakes. As recently as 1986, the lake burped a massive plume of carbon dioxide, suffocating around 1,700 people and 3,500 animals in nearby villages. It was the first known large-scale asphyxiation ever recorded from a natural event.
