Main image

Llyn Padarn is a glacial lake in north-west Wales located at the foot of Snowdon, adjacent to the village of Llanberis. It is one of the principal natural lakes in the Llanberis area and a local focus for outdoor recreation.

The lake provides lakeside walking routes, watersports launch points and views towards the surrounding mountains and quarry landscapes. Facilities and visitor services are concentrated in Llanberis at the lake’s northern end, making it a convenient base for short or extended visits.

Llyn Padarn occupies a glacially carved valley and has been shaped by the same ice processes that formed the adjacent mountain scenery. Over time the area developed recreational uses linked to nearby quarries, the village and mountain tourism.

The lake sits next to Llanberis in Snowdonia National Park in north-west Wales, with public access from the village and surrounding minor roads. It is set at the foot of the Snowdon massif and is a short walk from the village centre.

  • Recreation: The lake lies immediately south of the village of Llanberis and is frequently used for walking, running and non-motorised water sports.
  • Access: Several established paths run along the shore and link to wider Snowdonia routes, providing easy lakeside access from the village.

What to See #

  • Llanberis: A village at the lake's northern end that provides visitor services, parking and access to the lakeshore and nearby attractions.
  • Padarn Country Park: A public park and lakeside area offering paths, picnic spots and launch points for small craft along the shore.
  • Llyn Peris: A smaller adjacent glacial lake to the south that lies close to Llyn Padarn and is separated by a narrow isthmus.
