This rewarding out-and-back mountain walk climbs Yr Aran via the atmospheric Cwm y Llan, combining quiet high-level scenery with the striking remains of an old slate quarry on the southern flanks of Snowdon.
You’re in the right place if you’re looking for a quieter, more adventurous mountain walk with steep sections and short scrambling, suited to confident walkers who enjoy less crowded routes in good conditions.
The route passes through Cwm y Llan Quarry, once a thriving slate-working site high on the mountainside. Today, its abandoned buildings, inclines, and scattered slate form a dramatic reminder of Snowdonia’s industrial past and provide a fascinating pause along the way.
Beyond the quarry, the path steepens as it climbs towards Yr Aran. Although the ascent is demanding in places, the route remains clear, with only a couple of short, unexposed scrambling sections adding interest rather than technical difficulty.
From the summit of Yr Aran, wide-ranging views open out across Yr Wyddfa, Cwm Llan, and the surrounding high ground. The quieter nature of this peak gives the top a remote, satisfying feel, making the effort well worthwhile.
For experienced walkers staying at Perthi Holiday Cottages, this walk can be started directly from the farm — no car needed. The route from the cottages is less obvious than the main paths so please refer to the guestbook for directions before setting out.
“This is Snowdon’s quieter neighbour and genuinely one of the most rewarding walks near Beddgelert — the summit views of Yr Wyddfa are as good as anything you’ll get from the top of Snowdon itself, with almost nobody else up there. If you’re staying at Perthi and you’re an experienced walker, ask us about the route from the farm — it’s a special way to start the day.” — Delyth, Perthi Holiday Cottages
