Mount Snowdon (via Llanberis Path)

Mount Snowdon via the Llanberis Path earns a strong 9/10 for dog friendliness, and it's widely considered one of the great dog-friendly summit experiences in Britain. The Llanberis Path is the longest but most gradual route to the top, making it the most practical choice for dogs, and the wide, well-worn trail is easy to follow in clear conditions. That said, this is a serious mountain day rather than a casual outing , it's best suited to fit, experienced dogs that are calm and confident on exposed terrain.

Dogs need to be kept on a lead on the lower slopes, which cross grazing land with sheep present year-round , leads are essential until you clear the farmland at around 700 metres. Above that, the upper ridge is narrow and exposed with steep drops on both sides, so any dog that pulls or lacks confidence should stay on lead throughout. This really is a route for calm, steady dogs rather than excitable or reactive ones.

This is a full-day mountain commitment , 14.5km out-and-back with 975 metres of ascent , so your dog should be fit and experienced before attempting it. Carry plenty of water, as streams are available on the lower sections but the upper mountain is dry. Weather is a crucial factor: cloud can descend rapidly and conditions on the upper ridge can change dramatically, so pick a clear, calm day and be prepared to turn back if things deteriorate. The walk is not suitable for nervous, reactive or elderly dogs.
