Mount Snowdon (via Llanberis Path)
Gwynedd
Yr Wyddfa (Snowdon) at 1,085 metres is the highest peak in Wales, and the Llanberis Path is the longest but most gradual route to its summit, making it the most practical choice for dogs. The 14.5km out-and-back climbs steadily from Llanberis alongside the Mountain Railway, passing the Halfway House café before the gradient steepens above Clogwyn Station and the final exposed ridge leads to the summit visitor centre, Hafod Eryri. The path is wide and well-worn throughout, with 975 metres of ascent spread across the full distance. Navigation is straightforward in clear conditions, though cloud can descend rapidly and the upper mountain is a different proposition in poor visibility.
This is a full-day mountain commitment rather than a casual dog friendly walk. The lower slopes cross grazing land where sheep are present year-round, so leads are essential until you clear the farmland above roughly 700 metres. The upper ridge is narrow and exposed in places, with steep drops on both sides, demanding a calm, confident dog that won't panic or pull. Water is available from streams on the lower sections but the upper mountain is dry, so carry plenty. The thin air and bare rock of the summit ridge carry a sharp mineral scent that changes the whole atmosphere of the walk. Best tackled on a clear, calm day with a fit, experienced dog. Not suitable for nervous, reactive or elderly dogs.
