The Llanberis Path is the most popular route up Yr Wyddfa, and for good reason. It’s the longest route by distance but the most gradual in gradient, making it the most forgiving approach to the summit. The path follows the Snowdon Mountain Railway for much of its length, passing the Halfway House café and Clogwyn station before the final steep pull to the top.

Route Description
The path starts near the Royal Victoria Hotel in Llanberis (SH 582 597), heading south up the initial slopes through farmland. A gate marks the start of open mountain. The path climbs steadily south, running parallel to and often visible from the Snowdon Mountain Railway. The going is generally on a good, well-worn path: this is one of the most walked mountain routes in Britain, and the trail surface shows it. Each summer it is also the course of Ras yr Wyddfa, the Snowdon Race, and our guide to where to watch on the Llanberis Path picks out the best spots.
After approximately 3km and 400m of ascent, you reach the Halfway House café (open in season, serving hot drinks and snacks, one of the most welcome sights in Welsh mountaineering). Just above the Halfway House, the path passes under the railway line and continues more steeply upward.
Above the Halfway House, the gradient increases and the views open dramatically. The Llanberis valley stretches out below, with Llyn Padarn and Llyn Peris visible in the valley floor. To the east, the great cwms of the Glyderau come into view. The path passes Clogwyn station, the halfway point on the railway and often its terminus on blustery days, and then climbs more steeply through a section of loose, eroded ground.
The route passes above the impressive cliffs of Clogwyn Du’r Arddu, “the Black Cliff of the Black Height”, one of the most celebrated rock climbing venues in Britain, where generations of climbers pioneered routes that pushed the boundaries of the possible. The cliff faces northwest and rarely sees direct sun, giving it a sombre, imposing character.
From Clogwyn station, the path climbs more steeply to the junction with the Ranger Path (coming up from the west) and then makes the final pull to the summit plateau, joining the convergence of routes from all directions at the base of Hafod Eryri, the summit visitor centre.
What to Expect
The Llanberis Path is long but never technically difficult. The path is clear and well maintained throughout. The main challenges are the sheer length (7.25km one way, not counting the descent), the altitude gain, and, overwhelmingly, the weather. This side of the mountain is exposed to southwest winds off the Atlantic, which can be ferocious. Even in summer, gusts above 60mph have been recorded at the summit, and rain can appear with very little warning.
The path is heavily eroded in places, particularly above the Halfway House. Path restoration work by the National Park and partners has improved many sections but some remain loose and uneven, especially in the wet.
Variations and Combinations
Many walkers combine the Llanberis Path with the Pyg Track or Miners’ Track for a linear traverse: ascend via Llanberis, descend via the Pyg Track to Pen-y-Pass, and take the Sherpa’r Wyddfa bus back to Llanberis (check the current timetable before relying on it). This is a highly recommended combination, with more varied scenery in each direction, and the Pyg Track’s spectacular views of Glaslyn and Llyn Llydaw make for a memorable descent.
Alternatively, descend via the Miners’ Track to Pen-y-Pass, combining two of the most walked paths on the mountain.
Practical Tips
Start early: the Llanberis car parks fill quickly in summer, and the summit is noticeably less crowded before 10am. The path runs alongside the railway in places, so take care on the steep sections. Don’t count on the Halfway House being open in poor weather or early and late in the season. Carry sufficient water: there is no reliable drinking water on the path above Llanberis village.
