Aber Falls, or Rhaeadr Fawr, is a 37-meter high waterfall situated in the foothills of the Carneddau mountain range in Snowdonia. The water plunges from the Afon Goch river over a series of igneous rock steps into a plunge pool. The trail to the falls is a gravel-surfaced path accessible from the Abergwyngregyn village car parks. The path traverses a meadow and woodland setting, offering views of the valley and the Menai Strait. The site is a National Nature Reserve managed by Natural Resources Wales. The waterfall is fed by the confluence of three streams, including the Afon Goch, which originates in the high mountains above.
The wooden bridge crossing the Afon Goch offers a direct, centered view of the waterfall drop.
Wear sturdy, waterproof hiking boots as the path can be muddy near the base of the falls.
Check the local weather forecast specifically for the Carneddau mountain range, as conditions differ significantly from coastal areas.
Carry a physical map or offline GPS, as mobile reception is inconsistent within the valley.
Attempting to climb the rock face surrounding the waterfall, which is unstable and slippery.
Keep dogs on leads due to roaming livestock in the meadow; do not swim in the plunge pool due to dangerous currents and submerged rocks.
