Aber Falls (Rhaeadr Fawr)
Gwynedd
The walk to Rhaeadr Fawr follows the Aber valley inland from Abergwyngregyn on wide, well-maintained paths through open grassland and patches of sessile oak. The waterfall itself drops 37 metres in a single white curtain at the valley head and is one of the most impressive in Wales. A circular route of 6.5 km returns via higher ground with views back down the valley, passing old farm walls and scattered hawthorn on the upper slopes. The route is well signed and easy to follow throughout, with only gentle climbing despite the 140 m of elevation gain spread across the full circuit.
Dogs and their owners get a genuinely rewarding dog friendly walk here without needing full mountain fitness. The Afon Rhaeadr runs alongside much of the outward path, offering regular water access, though the current runs fast after rain and care is needed near the falls. Sheep graze the valley floor and surrounding hillsides year-round, so leads are required for most of the route. The wide, firm paths suit larger or older dogs who would struggle on rougher mountain terrain, and the valley setting provides shelter on windier days. The return leg on higher ground opens up the views and gives a real sense of the Carneddau foothills without committing to the full mountains above.
