Ceunant Mawr Waterfall, Llanberis

A Hidden Natural Wonder in Snowdonia

Ceunant Mawr Waterfall, translating to "the waterfall of the great ravine," is a captivating natural feature located just outside the village of Llanberis in North Wales. Part of the Snowdonia National Park, this waterfall is fed by the Afon Arddu river, which plunges dramatically over rocky cliffs in two main stages. The falls cascade approximately 20 meters at the main viewpoint, with the river dropping over 30 to 60 meters along its course. The waterfall’s setting is characterized by a gorge lush with moss, ferns, and woodland, creating an emerald-hued, tranquil atmosphere that enchants visitors year-round.

Accessible Trails and Scenic Walks

The waterfall is reachable by an easy and well-marked trail starting near the Snowdon Mountain Railway station or from various nearby car parks in Llanberis. The walk is roughly 1 to 2.2 kilometers round trip, with gentle elevation gain, making it suitable for most fitness levels and families. The path follows the river through a peaceful wooded gorge, with small cascades and rich greenery along the way. Visitors can explore both the lower falls viewing platform and a steeper, short path to the upper falls, where views of the twin cascades and the surrounding rugged landscape offer excellent photo opportunities.

Visitor Experience and Safety Considerations

Ceunant Mawr Waterfall provides a serene escape from busier tourist spots, especially popular after heavy rainfall when the cascades are at their most powerful. The concrete and dirt paths are generally easy to navigate but can become slippery when wet, so caution is advised.

The site lacks on-trail facilities, but amenities such as restrooms, food options, and parking are available in nearby Llanberis village. The waterfall is also dog-friendly, with many visitors bringing pets along the walk.
