Llanberis, Wales
By The Alpines · Updated 2025-07-22 · 8 min read
The Llanberis Path is the longest but most gradual of the six main routes up Yr Wyddfa (Snowdon), the highest mountain in Wales and England at 1,085m. Following the line of the Snowdon Mountain Railway, it climbs at a steady, forgiving gradient, which makes it the most popular choice for first-time mountain walkers and for the Welsh leg of the National Three Peaks Challenge.
From Llanberis the path rises gently through farmland before joining the railway and climbing across the mountain's open western flank. It passes under Clogwyn station and steepens for the final pull to Bwlch Glas, where it meets the Pyg and Miners' tracks, before the last stretch to the summit ridge and the highest point in the country.
Being the gentlest route does not make it a soft one — it is still nearly 1,000m of ascent and 14.5km round trip, exposed to the full force of mountain weather, and busy enough that the summit can feel crowded in summer. But on a clear day, the views across Snowdonia to the sea are unforgettable, and the well-made path makes it the most achievable of the National Three Peaks summits.
The path leaves Llanberis on a steep tarmac lane before easing onto the open mountain and joining the railway line. This long middle section climbs at a steady, manageable gradient across grassy and rocky slopes, passing the Halfway House refreshment hut. It is honest, rhythmic walking — good for settling into a pace.
Above Clogwyn the path steepens and passes under the railway near the exposed Clogwyn Coch. It climbs to Bwlch Glas at the top of the Pyg and Miners' tracks, marked by a tall finger stone, then follows the summit ridge alongside the railway to the trig point on Yr Wyddfa. Take care in wind here — the ridge is exposed on both sides.
The Llanberis Path is walkable year-round in good conditions, but late spring to autumn is the safest window, when the path is snow-free and daylight is long. Summer weekends and school holidays are extremely busy — start early to beat the crowds and the car-park scramble in Llanberis.
In winter, snow and ice transform Snowdon into a mountaineering objective, and the exposed section near Clogwyn and the summit ridge become genuinely hazardous — ice axe, crampons, and winter skills are essential. Check the Met Office mountain forecast for Snowdonia before every walk.
The most forgiving route up Snowdon, but still a full mountain day — nearly 1,000m of ascent over a steady 7km climb and the same back down. Endurance and consistent pacing matter more than power; the gradient rarely bites, but the length adds up.
Around 975m of climbing spread over a long, even gradient — several hours of continuous walking
The stretch near Clogwyn and the summit ridge are exposed to wind and drops in poor weather
A 7km walk back down that tires the legs, especially the knees, on the rocky sections
