Llyn Padarn

Llyn Padarn stretches 3.2 kilometers in length with a depth of 29 meters, forming one of the largest natural bodies of water in Wales.

The lake formation dates back to the last ice age when glaciers carved through the valley, creating this natural water reservoir between mountains.

The northeastern shore features the National Slate Museum, documenting the industrial heritage of Welsh slate mining through exhibits and demonstrations.

Visitors can participate in water activities including swimming, kayaking, canoeing, and fishing, while the Llanberis Lake Railway operates along the shore.

The lake contains a population of Arctic char, a rare freshwater fish species that survived since the last glacial period in these waters.
