Llwybr Cwellyn
Snowdon Ranger Path
The oldest route — no scrambling, no exposed ridges, less-travelled
Introduction
The Snowdon Ranger Path is historically the oldest of Snowdon's six main ascent routes — 18th-century visitors used this path when guided by John Morton, a local innkeeper who called himself the 'Snowdon Ranger.' It is the only route where the Welsh and English names are entirely different (Llwybr Cwellyn vs Snowdon Ranger Path). It is also one of the quieter routes and the second-easiest, offering a clear, well-waymarked ascent without exposed ridges or scrambling — making it a genuine option for capable beginners seeking an alternative to the busy Llanberis Path.
Route overview
Starting from Llyn Cwellyn on the mountain's western flank, the path immediately crosses the Welsh Highland Railway line and ascends through pastoral hillside. It rises steadily across open mountain terrain above Cwm Clogwyn and the small Cwellyn lakes, passing above the dramatic Clogwyn Du'r Arddu cliffs, before joining the Llanberis Path at Bwlch Glas for the final approach to the summit.
- Start point
- Llyn Cwellyn car park (LL54 7YS, SH 564 551) at 180 m, opposite YHA Snowdon Ranger hostel
- End point
- Yr Wyddfa summit / Hafod Eryri visitor centre (1,085 m)
- Ascent profile
- Consistent and steady ascent throughout without significant flat sections. The upper section becomes steeper approaching Bwlch Glas but there are no sudden dramatic changes in gradient. A more sustained route than the Llanberis Path but without that route's length.
- Route type
- out and back
Terrain and navigation
Terrain: Well-maintained path throughout with clear waymarking. The lower section is pastoral; the upper section is more open mountain terrain with some rocky surfaces. No scrambling or exposed ridges. Proper walking boots are still required.
Navigation: Clear and well-waymarked throughout, making this an accessible route from a navigation perspective. In cloud, the junction at Bwlch Glas with the Llanberis Path and other routes requires attention.

Scenery and photography
Llyn Cwellyn below and to the west is a beautiful, calm lake. The Mynydd Mawr ridge provides a dramatic backdrop. The Clogwyn Du'r Arddu cliff face — Britain's most important rock-climbing crag — is visible from the upper section. Summit views are the same as from any other route.
Steady, clear, and satisfying. Less dramatic than the Pyg Track or Rhyd Ddu Path, but more characterful than the Llanberis Path in terms of remoteness and quietness. The views west over Llyn Cwellyn and the Nantlle Ridge are excellent.
Photography notes
Llyn Cwellyn reflections from the lower path in morning or evening light. Views of the Clogwyn Du'r Arddu cliff face from the upper middle section. The route's quietness allows for landscape photography with fewer people in the frame.
Who this route suits
Suited for
- Capable beginners who want a quieter alternative to the Llanberis Path
- Walkers comfortable on clear mountain paths without technical difficulty
- Those staying at YHA Snowdon Ranger
- Those arriving by Welsh Highland Railway
- Walkers combining with the Llanberis Path for a one-way descent
Not suited for
- Complete beginners without any hill-walking experience
- Those not carrying proper walking boots and waterproofs
- Winter walkers without mountaineering equipment (the upper section is still serious in winter)
Advantages
- Second-easiest route — no scrambling, no exposed ridges
- Well-waymarked and clear throughout
- Significantly quieter than the Llanberis Path
- The oldest named summit route with genuine historical character
- Adjacent to YHA Snowdon Ranger — ideal base for walkers
- Accessible by Welsh Highland Railway to Snowdon Ranger halt
- Can be combined with the Llanberis Path for a one-way descent
- Car park rarely fills
Considerations
- Less dramatic scenery than the Pyg Track, Watkin Path, or Rhyd Ddu Path
- Still a serious mountain route despite its relative accessibility
- Llyn Cwellyn is more remote — fewer nearby facilities than Llanberis
- Distance to major services means it suits self-sufficient walkers better
Seasonal considerations
A good all-season route for equipped walkers. In winter the upper section and Bwlch Glas can carry ice and require appropriate equipment. The lower pastoral section can be muddy in winter and spring.
Preparation advice
- Check weather and wind forecast — the upper section is very exposed to westerly winds
- Verify Welsh Highland Railway timetable if planning to arrive by rail
- Allow at least 3 hours for the ascent
- Consider staying at YHA Snowdon Ranger for a convenient base
Common mistakes to avoid
- Confusing 'second-easiest' with 'easy' — this is still a serious mountain route
- Not checking the Welsh Highland Railway timetable before planning a car-free approach
- Ignoring the wind exposure on the upper ridge section
Safety warnings
- In winter the upper section requires ice axe and crampons. Do not underestimate the summit ridge conditions because of the path's relatively accessible lower section.
- Strong westerly winds are common on this western approach — dress accordingly.
