Climbing Yr Wyddfa, the highest mountain in Wales, is a bucket-list experience for thousands of walkers each year. Standing proudly at 1,085 metres, it offers breathtaking views across Eryri (Snowdonia) National Park and, on a clear day, as far as Ireland. But while the mountain’s beauty is undeniable, its conditions can be unforgiving – particularly in autumn and winter.
In these colder months, the challenge isn’t just about the incline or the distance. Shorter daylight hours, icy paths, unpredictable rain and biting winds make preparation even more important. The difference between a rewarding adventure and a risky ordeal often comes down to having the right clothing and equipment.
This guide is designed to help you plan a safe and comfortable climb, with practical advice on what to wear and pack when tackling Yr Wyddfa in autumn and winter.
Safe Footwear is a Must
The foundation for any mountain walk is proper footwear. On Yr Wyddfa, where paths can shift from muddy to rocky to icy within a single hour, boots are your best friend.
- Waterproof hiking boots – Look for waterproof boots that keep your feet dry while allowing breathability. High ankle boots also provide extra support on uneven ground.
- Solid soles – Deep tread patterns grip well on wet rocks and icy patches.
- Warm socks – A good pair of hiking socks, ideally made from merino wool, helps regulate temperature and reduce blisters.
- Gaiters – These are especially useful in winter, stopping snow, rain and mud from getting into your boots.
Leaving the trainers behind is the answer to safety and comfort during your hiking adventure. Sturdy boots can be the difference between completing your walk or turning back early.
Layer Your Clothing to Prepare for Unpredictable Weather
The best way to deal with Yr Wyddfa’s unpredictable weather is to layer your clothing. This lets you add or remove items as conditions change and as your body warms or cools.
- Base Layer – Opt for lightweight, breathable tops and leggings made of synthetic fibres or merino wool to help keep your skin dry even when you sweat.
- Mid Layer – Fleece jackets or insulated down/synthetic jackets trap heat. A fleece is versatile for milder autumn days, while a puffy insulated jacket is invaluable on freezing winter Yr Wyddfa climbs.
- Outer Shell – Waterproof and windproof jackets and trousers shield you from driving rain and chilling winds. Look for breathable fabrics to avoid overheating.
- Accessories – Don’t underestimate the value of small extras:
- Warm hat and gloves (consider carrying a spare pair in case one gets wet).
- Neck buff or scarf to protect against cold air.
- Use sunglasses and sunscreen for glare. Even in winter, snow and low sun can be dazzling.
By mixing these layers, you’ll be ready for everything from sunshine at the base to sleet at the summit.
The Essential Equipment for Autumn and Winter Hikes
Packing the right gear makes your walk safer and more enjoyable. Your rucksack (20–30 litres is ideal) should contain:
- Map and compass – GPS is useful, but batteries fail quickly in the cold. Being able to navigate traditionally is essential.
- Headtorch (with spare batteries) – With daylight ending early, it’s easy to find yourself descending in the dark. A headtorch leaves hands free for safety.
- Food and water – Energy-rich snacks like nuts, flapjacks or chocolate keep your energy up. Water is essential but remember it can freeze in sub-zero conditions – keep bottles insulated or close to your body.
- First aid kit – Include plasters, blister pads and a foil blanket. A whistle is also a good addition for signalling.
- Trekking poles – While optional, trekking poles can help with balance on steep, icy or uneven terrain.
Seasonal Considerations: Autumn vs Winter
Autumn and winter can be some of the most magical times to explore Yr Wyddfa. With fewer crowds, crisp air and snow-dusted peaks, the mountain takes on a quiet, dramatic beauty that feels worlds away from the busy summer months. For many walkers, the sense of peace and accomplishment is even greater in the colder seasons. Here are a few things to consider if you’re hiking in autumn and winter:
Autumn:
- Weather is changeable, often with rain and strong winds.
- Paths may be muddy, especially after heavy rainfall.
- Visibility can be patchy as mist rolls in, especially in late afternoons.
Winter:
- Higher paths may be covered in snow and ice.
- Temperatures can dip well below freezing, particularly at the summit.
- Crampons or microspikes may be necessary for grip on icy ground.
- Ice axes are recommended for experienced walkers tackling steep, frozen routes.
In both seasons, always check the forecast before setting off. The Met Office mountain forecast and Yr Wyddfa Live provide up-to-date conditions.
Choose Your Route Wisely
Not all paths up Yr Wyddfa are equal – some are more forgiving than others, especially in winter. The Llanberis Path, starting in the village itself, is considered the most straightforward and accessible.

Staying Safe on YR WYDDFA (Snowdon)
Mountain safety is about more than equipment – it’s about mindset. If the unpredictable weather conditions worsen, know when to turn back. The summit will always be there for you to climb another day. It’s more important to stay safe. The Llanberis Mountain Rescue team is one of the busiest in the UK, so please carry the right equipment with you to reduce preventable callouts – but remember they’re always there if you do get into trouble.
