    Nestled within the heart of New Zealand's Southern Alps lies a natural wonder that has captivated travelers and nature enthusiasts alike: the Blue Lake of Nelson. Known as Rotomairewhenua in Māori, this pristine body of water boasts the title of the world's clearest lake, offering a mesmerizing experience for all who venture to its shores.

    What is Blue Lake? 

    The Blue Lake, or Rotomairewhenua, is a small yet significant lake located in the Nelson Lakes National Park. It's not just any ordinary lake; it's a testament to nature's beauty and the rich cultural heritage of New Zealand.

    The world's clearest lake: Imagine peering into a body of water so clear that you can see up to 80 meters deep. That's the magic of the Blue Lake. Holding the record for the clearest water in the world, it offers unparalleled visibility, revealing water's natural blue-violet hue.

    The lake's clarity is not just a fluke. It's a result of underground seepage from the neighboring Lake Constance, which filters out nearly all suspended particles. This natural filtration process, combined with the lake's unique geographical location, gifts it with its exceptional water quality.

    A sacred site for Māori 

    The Blue Lake, known to the Māori as Rotomairewhenua, is more than a scenic marvel. For the Māori, it's a spiritual and cultural touchstone. Historically, the lake was used by the Ngati Apa ki te Ra To iwi for rituals, specifically to cleanse the bones of deceased men, aiding their spirits on their journey to the afterlife. The neighboring Lake Constance played a similar role for the bones of women.

    Given its profound significance, certain protocols are in place to maintain the lake's purity and respect its cultural importance. Visitors are urged to recognize its sanctity, ensuring that the lake remains a revered site for both its natural beauty and its deep-rooted Māori traditions.

    The lake's Māori name, Rotomairewhenua, translates to "the lake of peaceful lands." It's deeply revered, with legends and stories echoing its importance in Māori traditions.

    Can I swim in Blue Lake?

    Swimming in Blue Lake is prohibited. This is because the lake is sacred to Māori, and swimming in the lake is considered to be disrespectful. Additionally, the lake's water is very cold, and swimming could be dangerous.

    • By bus: Several tour operators offer trips to the park, ensuring a comfortable journey.
