The cleanest lake on Earth where you can't swim

The cleanest and at the same time the most beautiful lake on our planet is called Blue Lake and is located on the South Island of New Zealand. The first thought that arises when looking at this stunning body of water is to jump into its crystal clear water and splash around in it until exhausted. But, unfortunately, this is strictly prohibited!

Incomparable landscape. New Zealand's South Island is home to the last untouched wilderness.

Relict forests, steep cliffs and waterfalls make for a stunning landscape.

There, deep in the mountains, lies the cleanest lake on Earth, fed by the purest water source.

Blue Lake (or Rotomairewhenua in the Maori language - the indigenous people of New Zealand) is located in Nelson Lakes National Park on the South Island.

The water there is so clear that when diving you can see far in front of you.

Laboratory tests have shown that the visibility range is from seventy meters.

For comparison: in distilled water this figure is about eighty meters.

This photograph shows that the water in the lake is so clear that it cannot be distinguished from the air.

Due to nature conservation reasons, swimming in the lake is prohibited.

Only scientists can obtain special permission to dive into the lake to take photographs such as these.

Tourists are allowed to walk along the shore at any time.

Such photographs remain in the memory for a long time.
