Eryri National Park, WA
Waterfalls, slate ruins and a brutally steep finish to Yr Wyddfa's summit
Overview
This is not a good first mountain walk. The authority notes that alternative summit routes may suit first time Yr Wyddfa walkers better, and the neighbouring Rhyd Ddu Path is the natural comparison since the two share the final approach. Choose the Watkin Path if you already have hill experience and want the quarry history and Cwm Llan scenery, and accept a long, steep, loose finish in exchange. It is described as not among the busier routes, but it remains demanding throughout.

Trail guide
There and back again from Pont Bethania Car Park in Nant Gwynant (SH 627 507), climbing through Cwm Llan to the summit of Yr Wyddfa (Snowdon) and returning by the same line. The official figures are 13 km / 8 miles total for the round trip, not one way, with 1,015 m / 3,330 ft of ascent and about 6 hours of walking.
The payoff is a rare mix of waterfalls, quarry archaeology, the wide bowl of Cwm Llan, long mountain views and the summit itself.
Graded Hard / Strenuous, and the national park authority describes it as particularly challenging. Lower sections are woodland, streamside and open valley paths that walk easily. The upper route is rough rocky mountain terrain and scree, and the final section below the Rhyd Ddu junction is extremely steep and loose underfoot with possible scrambling. There is real exposure and the consequences of a wrong line are serious. Full hill walking gear is essential, and winter conditions may call for specialist equipment.
Navigation skills are essential, and a recommended local Explorer map for the area should be carried and used. The key detail to remember is that the Watkin Path does not drop directly from the summit: on descent you must follow the signed junction near the standing stone carefully to regain the Cwm Llan side rather than continuing down the Rhyd Ddu Path.
The path opened in 1892 and was one of the first footpaths in Britain created purely for recreation. Gladstone Rock commemorates that opening. The slate quarry remains, the crushing mill and the ruined Plas Cwm Llan give the valley a strong industrial past that is visible for much of the climb.
Parking at Pont Bethania is extremely limited, so plan your transport before you travel. The park authority asks visitors to use the park bus service, which stops at Pont Bethania. No route specific dog policy is published for this path, so anyone considering bringing a dog should check the current access signs and park guidance before setting out.
