What to Wear for Snowdon: Kit List by Season (2026)

Last updated: 25 September 2026 · research-based guide

For Snowdon (Yr Wyddfa), wear proper walking boots with grippy soles, moisture-wicking base layers and an insulating mid-layer, and carry a fully waterproof jacket and overtrousers, a warm hat and gloves, a map and compass, a head torch, food, water and a small first aid kit. That applies even on a sunny summer day, because the 1,085 m summit is typically several degrees colder than the valley (often close to 10°C colder), windier and frequently in cloud. In winter, when there’s snow and ice on the upper mountain, the list also includes an ice axe and crampons and the skills to use them. At that point Snowdon is a serious mountaineering objective, not a walk.

This guide is based on research, not on a walk we did ourselves. We’ve drawn on Eryri National Park Authority guidance, Mountain Rescue England and Wales advice, Met Office mountain forecasting, published route data and feedback from owners of the kit. It’s written for anyone asking “what should I wear for Snowdon?” or “what do I take up Snowdon?”, whatever the season.

Snowdon quick facts

Summit height: 1,085 m (3,560 ft), the highest point in Wales. Distances and ascents are rounded from Eryri National Park Authority and Visit Snowdonia route data. Your own time will depend on fitness, stops, weather and ground conditions; try our walking time calculator. Eryri rates every summit route as hard/strenuous.

The core Snowdon kit list

This is the year-round baseline. It’s close to the Eryri National Park Authority’s own list of essentials. For a printable, general version, see our hiking gear checklist.

What changes by season

The key thing to understand is the difference between the valley and the summit. Air typically cools by around 2–3°C for every 300 m you climb, and Snowdon’s summit sits roughly 750–1,000 m above the main trailheads. Add wind chill and it can feel like a different season at the top. The figures below are indicative typical ranges, not a forecast. Always check the Met Office mountain forecast for Snowdonia before you go.

Spring

Spring is the season that catches people out most, because the car park can be mild while the upper slopes are still icy. Take the full core list plus a thicker mid-layer and winter gloves. Check the Eryri National Park ground conditions reports, which run through the winter season into spring. If there’s snow or ice above the zig-zags or Bwlch Glas, winter rules apply.

Summer

Summer is the busiest season, and many rescue call-outs involve walkers who are poorly equipped for a mountain day. Wear breathable layers and carry waterproofs, a warm layer, a hat and gloves anyway, because summit wind chill can approach freezing even in July. Bring at least 2 litres of water on warm days, and sun protection. Book Pen-y-Pass parking in advance or use the Sherpa’r Wyddfa bus.

Autumn

Autumn brings more wind and rain and shorter days. A head torch stops being “just in case” and becomes essential. Pack an extra insulating layer and spare gloves, because wet gloves are useless. By late October the summit building has closed for the season, and the first snow can arrive from November.

Winter: serious mountaineering terrain

When Snowdon’s upper slopes are covered in snow or ice, it is winter mountaineering terrain, not a hill walk. Eryri National Park states that winter ascents require crampons and ice axes, and training to use them. Compacted snow near the summit becomes extremely slippery, and cornices (overhanging lips of snow) can form around Bwlch Glas and the summit edges. A slip on the steep, frozen ground above Clogwyn on the Llanberis Path, or on the zig-zags above Glaslyn, can be very hard to stop without an ice axe and the skill to self-arrest. Don’t treat the railway line as a safe alternative, as it’s often worse.

• Winter kit: stiff, crampon-compatible boots (B1 or better), walking-grade crampons (C1/C2), a walking ice axe, goggles, a spare warm layer (such as a synthetic belay-style jacket), thick and spare gloves, a balaclava or buff, a flask and an emergency shelter.
• Microspikes aren’t a substitute for crampons on steep, hard-frozen ground. They suit short stretches of icy path at lower angles only.
• Skills first: if you’ve never used an axe and crampons, book a winter skills course or hire a qualified guide before attempting a winter ascent.
• Check first: read the Eryri ground conditions reports and the Met Office mountain forecast, including the freezing level and wind.

Footwear: do you need walking boots for Snowdon?

For most people, yes. Eryri National Park advises boots with thick soles and high sides rather than trainers. All six routes have rough, rocky or loose sections, and wet slate and rock are slippery. Here’s how the choice changes with the season:

• Summer, dry forecast, experienced walker: sturdy trail shoes with an aggressive lugged sole can work on the Llanberis or Pyg paths. Boots are still the safer default for beginners, heavy packs and weak ankles.
• Spring and autumn: waterproof walking boots with ankle support and a Vibram-type grippy sole. Expect wet ground and possible early or late ice.
• Winter: stiff B1–B2 winter boots that take crampons. Flexible summer boots and trail shoes aren’t suitable.

Wear your boots in before the day, and pair them with proper hiking socks. If you’re buying your first pair, our best hiking boots for beginners guide covers comfortable, waterproof options that suit the Snowdon paths.

Layers and waterproofs

Layering is how you manage the big temperature swing between Pen-y-Pass and the summit:

• Base layer: a synthetic or merino T-shirt or long-sleeve top. Cotton stays wet and cold.
• Mid-layer: a fleece or lightweight synthetic insulated jacket, added at stops and at the summit.
• Shell: a genuinely waterproof, breathable jacket with a hood that has a stiffened peak, plus waterproof overtrousers. A showerproof “rain jacket” often isn’t enough in sustained Snowdon rain and wind.
• Extras: a warm hat, gloves and a buff. In spring, autumn and winter, carry a spare pair of gloves.

The Met Office warns that heavy, persistent rain can lead to significant loss of body heat and an increased risk of hypothermia in the mountains. A good shell is the single most important item. See our best rain jackets for hiking guide for waterproof ratings and owner feedback.

Head torch, food and water, navigation and first aid

Head torch: Eryri includes a torch in its essential kit list. A twisted ankle on the descent or a late start can easily push you past sunset, especially from October to March. Carry a head torch with spare batteries, or a charged spare, even in June. Our best headlamps guide compares brightness and battery life.

Food and water: allow 1.5–2 litres of water (more on hot days) and a proper lunch plus high-energy snacks. The summit café in Hafod Eryri is run by the Snowdon Mountain Railway, not the National Park. It generally opens only in the main season, typically from around May to late October, depending on the weather and on trains running to the summit, and it’s closed in winter. Treat it as a bonus, not your food plan. Don’t rely on catching the train down either, as seats aren’t guaranteed and services are weather dependent.

Navigation: carry the OS Explorer OL17 map (or the Harvey Snowdon map) and a compass, and know how to use them. The Met Office notes that poor visibility makes route finding challenging and that white-outs can occur when mist combines with snow cover. On the summit ridge in cloud, it’s easy to head down the wrong path. A phone app with offline maps is a useful back-up, not a replacement.

First aid: blister plasters, a small dressing, a bandage, painkillers, any personal medication and a foil blanket. Add a lightweight group shelter so an injured person can be kept warm while help arrives.

What size day pack for Snowdon?

For a summer day, a 20–30 litre day pack comfortably fits waterproofs, a warm layer, food, water and first aid. For spring, autumn and especially winter, a 30–40 litre pack gives room for extra insulation, a flask and an axe and crampons. Look for a hip belt, a chest strap and a rain cover or liner. Our backpack guide covers fit and features, and the same principles apply to day packs.

Trekking poles

Poles aren’t essential, but many walkers find them valuable on Snowdon’s long, stony descents, particularly the steep drop from Glaslyn on the Miners’ Track and the long Llanberis Path. They reduce strain on your knees and help your balance on loose ground. Stow them on sections where you need your hands, and in winter they are no substitute for an ice axe. See our best trekking poles guide.

Route focus: up the Pyg Track, down the Miners’ Track

This is one of the most popular circuits, at roughly 11–12 km with about 725 m of ascent, starting and finishing at Pen-y-Pass (359 m). Allow 5–7 hours.

1. Pen-y-Pass to Bwlch y Moch: a rocky, stepped path climbs west. At Bwlch y Moch, stay on the Pyg Track and don’t take the right-hand fork towards Crib Goch. Eryri describes Crib Goch as an extremely dangerous knife-edge ridge with no escape route.
2. Traverse above Llyn Llydaw and Glaslyn: a well-made but uneven path, with good views down to the lakes.
3. The zig-zags to Bwlch Glas: the steepest part, which is rocky and loose. The Miners’ Track joins here from below. At the marker stone on Bwlch Glas you meet the Llanberis Path. In winter this section is often icy or banked with snow.
4. Summit ridge: a short walk to the trig point at 1,085 m. Note your descent path carefully, especially in cloud.
5. Descent via the Miners’ Track: retrace the route to where the Miners’ Track branches down towards Glaslyn. This is a steep, loose descent, which is where poles and good boots help. Then take the easy lakeside track past Llyn Llydaw and along its causeway back to Pen-y-Pass.

→ Open the free Pyg Track / Miners’ Track route guide in the Peak Outdoor Guide app, with step-by-step directions, route data and key waypoints you can use on the day.

Getting there: Pen-y-Pass parking must be pre-booked through JustPark in the main season (Eryri says this runs until 1 November 2026, and it’s pay-and-display outside that period). Alternatively, park at Nant Peris or Llanberis and take the Sherpa’r Wyddfa bus (the S1, S2, S4 and S5 routes all serve Pen-y-Pass). Check the current timetable before you travel.

Safety: weather, turn-back times and calling for help

Snowdon is one of the busiest mountains in the UK for rescues. National Mountain Rescue England and Wales figures for 2025 show that Llanberis Mountain Rescue Team handled around 360 call-outs, roughly 10% of all call-outs in England and Wales that year. The North Wales Mountain Rescue Association says around 45% of incidents involve human factors, such as route choice, kit and timing, which are often preventable.

• Check the weather properly. Use the Met Office mountain forecast for Snowdonia, which gives summit temperatures, wind speeds at height, the chance of cloud-free summits and the freezing level, not just a town forecast. In winter and spring, also read the Eryri ground conditions reports. As a rough guide, gusts of 30–40 mph make balance difficult on exposed upper slopes, and 50 mph or more makes walking very difficult and dangerous.
• Set a turn-back time. Before you start, work out sunset and your descent time, then pick a time you’ll turn round wherever you are. Stick to it. The summit will still be there another day.
• Know when to turn back: the weather is worse than forecast, someone in the group is cold, tired or struggling, you’re behind schedule, or you meet snow and ice without the kit and skills for it.
• Tell someone your plan, including your route and expected return time.

How to call Mountain Rescue

Dial 999 or 112, ask for the Police, then ask for Mountain Rescue. Be ready to give your location (a grid reference if possible), the casualty’s name, age and sex, the nature of the injury or problem, the number of people in your party and your mobile number. Then stay where you are and keep your phone free, because the team may call you back.

Register for emergencySMS before you go. If you can’t make a voice call, you can text 999, but only if you’ve registered first. To register, text the word register to 999 and follow the reply. The service was set up for deaf, hard-of-hearing and speech-impaired people, and mountain safety organisations encourage walkers to register as a back-up for places with poor signal. Use it only when a voice call isn’t possible. Texts aren’t guaranteed to arrive, so wait for a reply confirming that help is coming.

Snowdon kit FAQ

What should I wear to climb Snowdon?

Wear walking boots, walking trousers (not jeans), a synthetic or merino base layer and a fleece mid-layer, and carry a waterproof jacket and overtrousers, a warm hat and gloves. The summit is typically several degrees colder than the valley, and often close to 10°C colder, as well as windier and frequently in cloud, even in summer.

Do I need walking boots for Snowdon?

For most people, yes. Eryri National Park advises boots with thick soles and high sides rather than trainers, because the paths are rocky, steep and slippery when wet. Experienced walkers sometimes use sturdy trail shoes in dry summer conditions. In winter you need stiff, crampon-compatible boots.

What should I take up Snowdon?

Take waterproofs, a warm layer, a hat and gloves, a map and compass, a head torch, a charged phone and power bank, 1.5–2 litres of water, lunch and snacks, a small first aid kit and an emergency shelter, all in a 20–30 litre day pack. Don’t rely on the summit café or the railway being open.

What should I wear for Snowdon in winter?

If there’s snow or ice on the upper mountain, you need winter boots, crampons, an ice axe, goggles, extra insulation and spare gloves, plus the training to use them. Winter Snowdon above the snowline is serious mountaineering terrain. If you lack winter skills, take a course, hire a qualified guide or choose a lower walk.

What should I wear on the Pyg Track?

Wear the same core kit as for any Snowdon route: walking boots with a grippy sole, layers, full waterproofs, a hat and gloves. The Pyg Track is rocky and steep near the zig-zags, so good footwear matters. Poles help on the descent, and you must avoid the Crib Goch turn-off at Bwlch y Moch.
