Route-specific day plan
One day — Watkin Path
A practical day plan for the Watkin Path from Pont Bethania in Nant Gwynant. The Watkin Path is the hardest of the six main routes — it has the greatest total elevation gain, starts from near sea level, and involves loose scree on the upper section. This plan is for experienced walkers who have chosen this route deliberately.
About this route
- Distance
- 13 km / 8 miles return
- Elevation gain
- 1,025 m — greatest of six routes
- Typical duration
- 6–7 hours return
- Start point
- Pont Bethania, Nant Gwynant (LL55 4NR)
- Difficulty
- Hardest of six routes
- Start elevation
- ~60 m — lowest of all trailheads
The Watkin Path starts from near sea level in the Nant Gwynant valley and rises through oak woodland, past the Gladstone Rock, through WWII commando training ruins and copper mine remains, before tackling a steep and exposed ascent to the summit ridge. The final approach involves loose scree that requires careful footing. The route is rich in history and scenery but physically the most demanding of the standard six paths.
Who this suits: Experienced mountain walkers who want a challenging and historically rich ascent, and who are comfortable on loose terrain. Not recommended for first-time Snowdon visitors, families with children, or anyone who has not walked on loose mountain terrain before.
Parking and getting there
Pont Bethania car park — the only option
The Watkin Path trailhead is at Pont Bethania in Nant Gwynant — not in Llanberis, not at Pen y Pass. The car park at Pont Bethania is small and can fill quickly on peak days. Advance booking is not available — it is pay-and-display. Arrive early on summer weekends (by 8am is advisable). If the car park is full, there is limited roadside parking — do not block passing places or verges.
Verify current charges at the official Eryri NPA parking page before travelling.
By public transport — Sherpa S4
The Sherpa S4 runs from Porthmadog through Beddgelert and stops at Pont Bethania (Nant Gwynant), serving the Watkin Path trailhead. This is the most practical car-free option for this route. Verify current timetable at the official Sherpa page — the S4 is a seasonal service.

Times are estimates for a fit, experienced adult in good summer conditions. The Watkin Path typically takes longer than other routes because the elevation gain is greatest. Plan conservatively.
Ascent — Pont Bethania to summit
Arrive at Pont Bethania car park. The later you start, the more demanding the descent becomes under time pressure — start early on a long route like this.
Begin the Watkin Path. The first section climbs through oak woodland along a clear path — it feels relatively gentle initially, but this will change.
Gladstone Rock — the huge boulder where Prime Minister William Gladstone addressed a crowd of 2,500 people in 1892 at the path's official opening. A natural pause point with historical context.
South Snowdon slate quarry ruins. The path flattens briefly through the industrial remains before the ascent steepens significantly.
Above the quarry, the path becomes steep and the terrain changes to loose scree. This section — the final approach to the summit ridge — is the most physically demanding and technically challenging part of the route. Take your time. The footing is unstable.
Summit ridge. The Watkin Path joins the summit plateau from the south — a different approach than the northern routes. Summit (1,085 m) and Hafod Eryri.
Allow 30–45 minutes. Note the time carefully — the Watkin Path descent requires full concentration and should not be rushed.
Descent — summit back to Pont Bethania
Begin descent. Return via the Watkin Path. The scree descent requires slow, careful movement — loose rock is most dangerous on the way down. Do not rush this section.
Back at Pont Bethania. Allow time for afternoon at Beddgelert (4 km from Pont Bethania by road) or Nant Gwynant — both are excellent after a hard day on the mountain.
Where the day becomes more committing
The quarry (upper path): Above the South Snowdon slate quarry, the path character changes entirely. The terrain becomes steep, rocky, and physically demanding. This is the decision point: if conditions are deteriorating above or the group is tiring, turn back here rather than committing to loose scree in deteriorating weather.
The scree section: Once on the upper scree, progress is slow and the terrain underfoot is loose. Turning back here requires the same careful movement as continuing. Do not underestimate how demanding the descent of this section will be.
Time: The Watkin Path takes longer than other routes. An 8am start is strongly recommended. Do not leave the summit after 1pm — descending 1,000 m of elevation in fading light via loose scree is a serious proposition.
Turnaround and fallback plans
Natural turnaround points: Gladstone Rock (accessible and rewarding for history); South Snowdon quarry ruins (a worthwhile destination without the upper ascent).
If conditions turn: The woodland lower section of the Watkin Path is sheltered and can be walked in most weather. Above the quarry is not a place to be in a storm.
Alternative if car park is full: Drive to Nant Gwynant layby and take the Sherpa S4 to Pont Bethania if available. Otherwise, consider an entirely different trailhead for the day — Rhyd Ddu (LL54 6TN) rarely fills and is about 20 minutes away.
