1. Blue Lake – New Zealand
New Zealand's lakes are renowned for their cleanliness, and Blue Lake in Nelson Lakes National Park is a perfect example of this. Nestled among ancient beech forests, this lake is considered one of the cleanest lakes in the world, with water so pure it seems almost unreal.
However, Blue Lake holds deep cultural significance to the Maori, so swimming is off-limits as a mark of respect for its sacred status. Instead, visitors are encouraged to take in the beauty of the lake - its pristine waters and tranquil surroundings. It's a place where silence and stillness speak volumes, allowing you to connect with nature deeply, without interruption.
