When visiting the lake, it’s important to check, clean, and dry all equipment and clothing to prevent the spread of invasive species that inhabit the area. The invasive species Lagarosiphon Major and Elodea Nuttallii inhabit the lake so it is important to ensure that you check your equipment, clean everything thoroughly and dry your gear for as long as you can.

Come take a dip in Padarn Lake, rich in history and nature. One of the best lakes in North Wales, it’s also designated as a Site of Special Scientific Interest thanks to its rich biodiversity, including the Arctic Char Luronium Natans and Cambrian Rocks. You can help us protect this unique environment by avoiding sensitive areas – for information download this map (PDF).

Beyond wildlife, Padarn Lake offers a glimpse into Wales’ geological past with its Cambrian rocks and industrial history, such as the Giant Waterwheel and remnants of old structures from a bygone era.

There are opportunities for climbing and scuba diving, as well as leisurely activities like lake cruises. Feeling adventurous? Plunge into our lake and embrace nature.

Safety information

Here are a few points to consider:

  • Our lake is 30m at its maximum depth, so it is important to be careful when swimming here.
  • Check the depth and terrain of the lake bed, as some areas may drop off abruptly.
  • Take your time entering the water to acclimatise to its temperature and avoid jumping or diving, especially given the presence of sharp slate below.
  • Plan your swimming route along the shoreline for easy access and visibility to passing boats. Ensure you’re easily identifiable by wearing a bright swim cap and towing a brightly coloured float.
  • Wearing a wetsuit can provide added warmth and buoyancy, but never swim alone—have support nearby, ideally with a canoe, kayak, or paddleboard displaying a white and blue Alpha flag as a warning to others.
  • Even on hot summer days, the lake’s cold temperature can lead to hypothermia, so limit your time in the water. Always check the weather conditions before swimming, as they can change rapidly.
Your safety is also important when paddleboarding, rowing, and kayaking. Ensure you wear a CE-approved life jacket or buoyancy aid and keep it on whenever you’re near the water. Always have a companion and stick close to the shoreline, as the wind can change direction suddenly, potentially causing drift to the opposite end of the lake.
