Mount Snowdon, or Yr Wyddfa as it’s known in Welsh, is the highest mountain in Wales and one of the UK’s most popular hiking destinations. Rising 1,085 metres above sea level, it attracts thousands of walkers each year, many bringing their dogs along for the challenge. But can dogs climb Mount Snowdon safely, and if so, which routes and conditions are best suited for them?
Author’s Experience: I climbed Mount Snowdon in 2023 with my friend and her dog, who is an experienced and sure footed spaniel / labrador mix that had multiple peaks under his belt already. We opted for the Pyg Track to ascend and the Miner’s Track to descend, which is a stunning and challenging route with some scrambling required. If your dog is experienced and you like a little bit of spice in your hikes, I would highly recommend this route.
This guide breaks down everything you need to know before tackling Snowdon with your four-legged companion, including route difficulty, preparation tips, and what to expect on the day.
Can Dogs Climb Mount Snowdon?
Yes, most dogs can climb Mount Snowdon, provided they are healthy, well-conditioned, and used to long, strenuous walks. The mountain’s network of routes offers options for a range of experience levels, though all involve several hours of uphill walking and potentially challenging terrain.
That said, Snowdon is not suitable for every dog. The ascent can be hard on some smaller breeds, senior dogs or those with mobility issues. It is essential to judge your dog’s fitness honestly before attempting the climb and this is not a hike for puppies or junior dogs that are still growing (unless you’re prepared to carry them for hours).
The Best Routes Up Snowdon with a Dog
There are six main routes to the summit (not counting the ridges, but more on that later), each offering a different experience and level of difficulty. Some are more dog-friendly than others due to surface type, gradient, and exposure.
1. Llanberis Path (Easiest and Most Popular)
- Distance: 9 miles (there and back)
- Time: 5–7 hours
- Terrain: Well-defined track, steady gradient
The Llanberis Path is the most popular route and by far the best choice for most dogs. It is a long, gradual climb with fewer hazards and plenty of places to rest. The trail follows alongside the Snowdon Mountain Railway for much of the way, with access to water from streams at intervals. There’s even a cafe on this route providing snacks and hot drinks, not something you will find on most peaks!
Best for: Fit dogs new to mountain hikes or those with moderate experience.
2. Miners’ Track (Scenic but Rocky)
- Distance: 8 miles (there and back)
- Time: 5–6 hours
- Terrain: Easy at first, then steep and rocky near the top
Starting from Pen-y-Pass, the Miners’ Track is scenic and manageable early on, but it becomes challenging where it joins the Pyg Track near Glaslyn Lake. Expect boulder sections, varying grades of scrambling and uneven footing.
Best for: Active, medium-to-large dogs used to rough terrain.
3. Pyg Track (Shorter but Steeper)
- Distance: 7 miles (there and back)
- Time: 5–6 hours
- Terrain: Rocky, steep, and exposed in places
The Pyg Track offers dramatic views and a shorter climb than Llanberis, but it is far more rugged. There are rocky scrambles and narrow paths that could be tricky for dogs, it runs across the same side of the mountain as the Miner’s track which makes it possible to use one for the ascent and the other for the descent if you want to vary your hike whilst still ending up at the same starting point (ideal if you’re parking a vehicle).
Best for: Experienced, confident dogs used to mountain hiking.
4. Rhyd Ddu Path (Quiet and Remote)
- Distance: 8.5 miles (there and back)
- Time: 6–7 hours
- Terrain: Rough mountain path with exposed ridges
A quieter alternative, the Rhyd Ddu Path offers solitude but involves some steep, exposed sections. Dogs must be sure-footed and under good control, as livestock are often grazing nearby.
Best for: Well-trained dogs and experienced walkers.
5. Snowdon Ranger Path (Historic and Moderate)
- Distance: 8 miles (there and back)
- Time: 6–7 hours
- Terrain: Gradual start, rockier upper section
This route is a steady climb with fewer crowds. The path can be loose and rough towards the top, but it is generally safe for fit dogs.
Best for: Dogs that enjoy long but steady hikes.
6. Watkin Path (Most Difficult)
- Distance: 8 miles (there and back)
- Time: 6–8 hours
- Terrain: Steep, with challenging scrambles near the summit
The Watkin Path starts beautifully through woodland and waterfalls, but the final ascent is steep, slippery, and potentially dangerous for dogs. Many owners choose to turn back before the final scree section.
Best for: Very experienced dogs and owners comfortable with demanding climbs.
Crib Goch and South Ridge
Two of Snowdon’s most famous routes, Crib Goch and the South Ridge, are often discussed by adventurous hikers, but they are not suitable for dogs. We only include these two routes as a word of caution to recommend that you do not hike them with a dog.
Crib Goch
Crib Goch is an exposed knife-edge ridge that requires scrambling and absolute focus. The route typically claims between 1-3 lives per year and there are sheer drops on both sides, even experienced mountaineers treat it with respect. Taking a dog along this route would be extremely dangerous and is strongly discouraged.
South Ridge
The South Ridge, accessed from Rhyd Ddu, is less extreme than Crib Goch but still features exposed, rocky sections with steep drops. While experienced humans enjoy its dramatic scenery, it is not an appropriate route for most dogs due to the uneven surfaces and lack of safe footing.
If you are seeking a challenge that remains dog-friendly, the Snowdon Ranger or Rhyd Ddu Path provide a better balance between adventure and safety.
Can Dogs Go on the Snowdon Mountain Railway?
Yes, dogs are allowed on the Snowdon Mountain Railway, making it a great option for those who want to experience the views without the full climb. Dogs are welcome on most trains for a small additional fare, although they must remain on a lead and sit on the floor beside their owner.
The railway runs from Llanberis to near the summit, with trains operating seasonally between spring and late autumn. In poor weather, or when the summit café is closed, trains may stop short of the top.
For many walkers, taking the train one way and hiking the other provides the perfect balance between adventure and comfort for both owner and dog.
Weather and Safety Considerations
Snowdon’s weather can change rapidly, and poor conditions can make the climb unsafe for dogs. Check the Met Office mountain forecast before setting off. Avoid climbing in extreme heat or during winter conditions when ice or snow can form on higher paths.
- Heat: Dogs can easily overheat on exposed trails. Carry plenty of water and rest often.
- Cold and Wet: Waterproof dog coats help prevent chills, and a towel is useful for drying off.
- Wind: High winds make exposed ridges hazardous, so avoid routes like Rhyd Ddu or Pyg Track on stormy days.
Preparing Your Dog for the Climb
- Fitness: Build stamina gradually with long, hilly walks.
- Paw Protection: Trails are rocky, so consider paw balm or protective boots if your dog’s pads are sensitive.
- Lead Control: Keep your dog on a lead around livestock and near steep drops.
- Supplies: Bring the essentials for your dog, including a collapsible water bowl, snacks, poo bags, and a first-aid kit.
Which Dogs Should Avoid Snowdon?
Snowdon is not ideal for every breed or age. Avoid taking:
- Puppies – Hiking with a puppy needs to be done with extreme care as their joints and bones are still developing
- Elderly dogs with limited stamina
- Flat-faced breeds such as Bulldogs that are prone to breathing issues
- Small dogs unless they are extremely fit and used to long walks (some small breeds are more suited to hiking)
If you are unsure, start with smaller mountains or lowland hikes before attempting Snowdon.
Facilities and Practical Tips
- Parking: Pen-y-Pass fills early; book parking in advance or use the park-and-ride from Nant Peris.
- Water: Natural sources are available but not always clean, so bring extra water for your dog.
- Summit Café: Open seasonally; dogs are not allowed inside but can rest outside with their owners.
- Campsites: There are a number of dog-friendly campsites a stones throw from Snowdon.
Final Thoughts
So, can dogs climb Mount Snowdon? Absolutely, as long as they are fit, well-prepared, and the conditions are right. Choose the Llanberis Path for an enjoyable, steady ascent, or the Miners’ / Pyg Tracks for something more adventurous. If you’re in the area and looking for something a bit different, there are plenty of amazing dog walks and hikes in Snowdonia National Park to consider.
Snowdon can be an incredible shared experience for you and your dog, but preparation, caution, and respect for the mountain are key.
