Yr WyddfaSnowdon · 1,085 m · highest ground in Wales

Six paths and one scramble to the roof of Wales, and weather that rewrites the mountain by the hour. What the day asks depends on the line you choose.

The highest ground in Wales: a broad massif of ridges and cwms above Eryri, reached by six named paths, one knife-edge scramble, and a rack railway to a summit café. What the climb asks of you depends on the line, so read the routes before you read the weather.

Practical brief

Your lineroute in practice ·

High start, rocky steps and lake views.

Start point
Pen-y-Pass car park, on the A4086
Parking / booking
Pre-book at Pen y Pass: very limited, no on-the-day guarantee. Or park at Nant Peris and ride the shuttle up.
Public transport
Sherpa'r Wyddfa buses serve Pen y Pass from Llanberis, Bangor and Beddgelert.
Facilities
Toilets and a café at Pen y Pass. Nothing on the route itself.
Return / descent
Back the same way, or drop down the Miners' Track from the junction below the ridge for a loop to the same car park.
Avoid this route if
Poor visibility, a late start, or winter underfoot without crampons and an ice axe. At Bwlch y Moch, stay on the main path: the gap in the wall is the way onto Crib Goch, not the Pyg.

A level lakeside walk to Glaslyn, then one steep climb to join the Pyg.

Start point
Pen-y-Pass car park, on the A4086
Parking / booking
As the Pyg Track: pre-book at Pen y Pass, or use the Nant Peris park-and-ride.
Public transport
Sherpa'r Wyddfa buses to Pen y Pass.
Facilities
As the Pyg Track. Nothing on the lakeside section or above it.
Return / descent
Back the same way: the flat lake path makes a forgiving final stretch. Coming down from the ridge, find the marked turn for the Miners' before the zig-zags, or you'll end up on the Pyg instead.
Avoid this route if
Winter conditions above the lakes without full kit. Turning back at Glaslyn, before the steep section, is still a good day out.

The longest, steadiest line: village to summit beside the mountain railway.

Start point
Victoria Terrace, Llanberis
Parking / booking
Park in Llanberis village car parks, not on side streets or residential roads.
Public transport
Sherpa'r Wyddfa buses to Llanberis Interchange from Caernarfon, Bangor and Betws-y-Coed.
Facilities
Full village facilities at the start. Two cafés sit on the path but only open seasonally: don't rely on them.
Return / descent
Back the same way: the most forgiving gradient on the mountain. Keep off the railway line, and at the top of the zig-zags make sure you're following the Llanberis line down, not the Pyg or Miners'.
Avoid this route if
Treating "easiest" as "easy": it's the longest route on the mountain, with nearly 1,000 m of climb. Snow and ice on the upper section without winter kit.

The biggest climb of the six: from near sea level, through woods and quarry ruins, to a loose final slope.

Start point
Pont Bethania car park, Nant Gwynant, on the A498
Parking / booking
Pont Bethania car park: extremely limited, often full by mid-morning. The National Park recommends the Sherpa'r Wyddfa bus instead.
Public transport
Sherpa'r Wyddfa buses serve Nant Gwynant from Beddgelert, Porthmadog and Betws-y-Coed.
Facilities
Toilets at the car park. Nothing on the route.
Return / descent
Officially there and back, but the upper slope is loose, eroded scree, easier and safer climbed than descended. Not a route to pick as your way down in poor visibility.
Avoid this route if
Your first ascent of Yr Wyddfa, descending the top scree in mist, or winter conditions without full kit.

The quietest line: an old quarry track, then a narrowing ridge to the top. The National Park doesn't publish an official ascent figure for this route, so treat the height climbed as an estimate, not a confirmed number.

Start point
Rhyd Ddu car park, off the A4085
Parking / booking
Rhyd Ddu car park, by the Welsh Highland Railway station: no booking system, but fills by mid-morning in peak season.
Public transport
Sherpa'r Wyddfa buses from Beddgelert, Caernarfon and Porthmadog.
Facilities
Toilets and a drinking-water tap at the car park. Nothing on the route.
Return / descent
Back the same way: Bwlch Main, the narrow ridge section, comes early in the descent, while legs are freshest. At the summit, leave by the steps past the visitor centre and don't drift onto the Watkin's scree line.
Avoid this route if
Strong wind or icy conditions on the final ridge: it narrows to a crest with drops on both sides. Not the route for anyone unsettled by exposure.

The oldest line up the mountain: quiet zigzags from Llyn Cwellyn, then steep ground above the cliffs.

Start point
Llyn Cwellyn car park, off the A4085
Parking / booking
Llyn Cwellyn car park: fewer spaces than Rhyd Ddu's, no booking system.
Public transport
Sherpa'r Wyddfa buses from Caernarfon and Porthmadog, stop "Snowdon Ranger YHA".
Facilities
Toilet at the car park. Nothing on the route.
Return / descent
Back the same way: near the top, leave the Llanberis line at the signed turn, and take care above the cliffs of Clogwyn Du'r Arddu in poor visibility.
Avoid this route if
Poor visibility on the upper section: the path climbs directly above the cliffs. Winter conditions without full kit.

A serious exposed scramble, not a walking route.

Start point
Pen-y-Pass car park, via the Pyg Track to the marked turn at Bwlch y Moch
Parking / booking
As the Pyg Track: pre-book at Pen y Pass, or bus.
Public transport
Sherpa'r Wyddfa buses to Pen y Pass, not a rescue plan.
Facilities
Pen y Pass only. Nothing on or near the ridge.
Return / descent
Traverse east to west, toward the summit: reversing mid-ridge is how people get stranded. The only recorded way off is at Bwlch Coch. The real decision point is back at Bwlch y Moch, before you touch the ridge.
Avoid this route if
Wet rock, wind, poor visibility, winter conditions, a first scramble, dogs — under any circumstances — or anyone unsure about serious exposure.

Public transport

Sherpa'r Wyddfa buses (opens in a new tab) link the valley towns to every trailhead: S1 Caernarfon–Llanberis–Betws-y-Coed, S2 Bangor–Llanberis–Pen y Pass, S3 Beddgelert–Caernarfon–Rhyd Ddu–Llyn Cwellyn, S4 Pen y Pass–Beddgelert–Porthmadog, S5 Llanberis–Pen y Pass.

Adult day ticket £7.50; family (2 adults + up to 3 children) £16. The myTrip app gives live tracking and cashless tickets. Walking up one path and down another is possible, but in practice the connection is often limited by the bus timetable. Check it before you commit to a linear route.

Toilets, food & water
  • Pen y Pass · toilets by the warden building; a YHA café/bar and an information-centre café opposite.
  • Llanberis · full village: cafés, pubs and shops, plus public toilets near the lake. Two seasonal cafés (Pen y Ceunant, Halfway House) sit on the path itself: never rely on them being open.
  • Pont Bethania, Rhyd Ddu, Llyn Cwellyn · toilets at each car park; Rhyd Ddu also has a drinking-water tap.
  • On the mountain · no toilets and no reliable water on any path between the car park and the summit.
  • Summit · café at Hafod Eryri, drinks and snacks only, seasonal (1 May–25 Oct, weather permitting). Outside the season, and on bad-weather days inside it, there's nothing at the top.
Dogs & livestock

Dogs must be on a lead of no more than 2 metres on open access land between 1 March and 31 July, and under close control near livestock at all times: a farmer may legally act against a dog attacking livestock. Dogs are not permitted on Crib Goch under any circumstances, or on the Snowdon Mountain Railway.

Routes & approach differences

The six named paths differ mainly in directness, crowding and exposure: the Pyg and Miners' Tracks share the busy Pen y Pass start (the Miners' begins flatter, past the lakes); the Llanberis Path is the longest but gentlest, running beside the railway; the Watkin climbs the most from near sea level, with loose scree near the top; and Rhyd Ddu and the Snowdon Ranger are the quietest lines, each narrowing to more serious ground near the summit: Bwlch Main's ridge on Rhyd Ddu, the cliffs of Clogwyn Du'r Arddu on the Ranger. Crib Goch is not one of these six: it's a separate, severe scramble, never a walking alternative.

Weather, visibility & winter conditions

Cloud is common on the summit and can hide the junctions where several paths converge, making the wrong descent line an easy mistake even when the climb itself went well. Wind is regularly much stronger at summit and upper-mountain level than anything felt in the valley, and wet or icy rock adds real difficulty to steps and zig-zags that are straightforward when dry. Snow or ice can turn any of the six walking routes into a winter mountaineering objective: an ice axe, crampons and the skill to use them may be needed, depending on conditions and the party's own competence, not as a fixed rule for every visit. Crib Goch is a separate, more serious case again: in wet, windy, wintry or otherwise poor conditions it isn't simply harder than the six paths, it's a different proposition entirely and shouldn't be attempted.

The Met Office publishes a location forecast for the Yr Wyddfa / Snowdon Summit point (opens in a new tab), and a separate Eryri/Snowdonia mountain forecast (opens in a new tab) that breaks conditions down by altitude — wind speed at 900 m, 600 m and 300 m, and the freezing level — figures a location forecast never carries. Read the first for the summit point and the second for the altitude picture; neither replaces your own judgement about summit wind, cloud, visibility, snow and ice. Yr Wyddfa Live (opens in a new tab) adds live summit and valley temperatures, current hazards and a webcam, and publishes ground-condition reports specific to the winter routes twice a week, Tuesday and Friday, through the season. Check them before assuming a walking route is still a walking route.

Descent planning & route mistakes

The Bwlch Glas standing stone is where the Pyg, Miners', Llanberis and Snowdon Ranger paths all converge just below the summit: in cloud, identify your line down before you leave the top, or you'll end up on the wrong path entirely.

The classic loop is up the Pyg, down the Miners', not the other way round. The Watkin Path's upper scree is easier and safer climbed than descended. On the Llanberis Path, keep off the railway line.

Emergency & what not to rely on

Dial 999 or 112 and ask for Police, then Mountain Rescue. Register for emergencySMS in advance so you can text 999 if you can't get a voice signal. Give your location, what's happened, and how many are in your group.

Llanberis Mountain Rescue Team covers this ground: one of the busiest teams in the UK. The railway, the buses and the car parks all run to a timetable, not to you: none of them is a rescue plan. AdventureSmart (opens in a new tab) sets out the basics: the right knowledge and skills, the right weather, the right gear.

Accessibility & realistic limitations

Every summit route is graded Hard/Strenuous by the National Park: there is no step-free or easy way to the top, and none of the six is an easy family walk despite the maintained look of paths like the Llanberis. First-timers are pointed toward the Llanberis Path. Blue-badge parking bays exist at Pen y Pass (first-come) and at Rhyd Ddu and Llyn Cwellyn (two spaces each).

The Snowdon Mountain Railway is the only non-walking way up: seasonal, weather-dependent, and best booked ahead. It does not sell single tickets down in advance; those are first-come-first-served at the summit on the day.

Specific to this mountain

Responsible visiting & local pressure

Park in a car park, not a layby or verge, and never walk or stop on the Pen y Pass road itself: it's narrow and dangerous. Wild camping isn't permitted anywhere in Eryri without the landowner's permission, and never in car parks or on verges.

Yr Wyddfa is a National Nature Reserve and working farmland. Take litter home and keep dogs under control near livestock. Around 600,000 people climb it each year (National Park figure); a quieter route such as Rhyd Ddu or the Snowdon Ranger spreads that pressure.

The reckoning

Now: is today the day?

You have seen the line and the climb; the last question is the weather. Yr Wyddfa is a fair-weather mountain: in cloud the summit is a navigation exercise, and the higher you go the less the valley forecast means.

The Met Office link is a location forecast for the Yr Wyddfa / Snowdon Summit point; MWIS is a regional mountain forecast for Eryri/Snowdonia; Yr Wyddfa Live adds live summit conditions and, in season, ground-condition reports for the winter routes. Read them together: none of them is a substitute for judging summit wind, cloud, visibility, snow and ice yourself. Valley sunshine does not guarantee a clear summit, and a late start eats the daylight you need to get down. Judge the day by the top, not the car park.

  • Cloudbase decides the view

    The summit sits in cloud on many days. The Met Office mountain forecast publishes the chance of a cloud-free summit: a figure a valley forecast simply doesn't carry.

  • Wind funnels on the ridges

    Bwlchau and ridge lines accelerate the wind well past the valley reading. On the exposed sections it turns people back before the gradient does.

  • The summit plateau whites out

    Up top the ground flattens and the paths converge. In mist, finding the finger-stone is the difference between the right descent and the wrong valley.

Winter is a different mountain. Snow and ice make the walking routes a full winter climb: axe, crampons, and the skills to use them. It is impossible to reach the summit safely without them.

Good fit for

  • Walkers ready for a graded but genuinely strenuous full mountain day
  • First-timers on the mountain willing to take the Llanberis Path
  • Anyone wanting a choice of six distinct approaches to one summit

Think twice if

  • You're expecting an easy family walk: every route is graded Hard or Strenuous
  • You need a step-free or accessible way to the top: none exists
  • You're drawn to Crib Goch without scrambling experience: it is a separate, severe proposition, not a sixth path

The summit

What the climb gives back.

You climb for the view, but the mountain does not always give it. On clear days the north opens; on cloud days, the cairn, the wind and the way down become the reward.
