This rewarding out-and-back walk climbs Mynydd Mawr from Rhyd Ddu, combining forest paths, open hillside, and wide-ranging summit views across Snowdonia and the coast.
You’re in the right place if you’re looking for a steady mountain walk with a sustained ascent and big views, rather than scrambling or technical terrain. Best suited to confident walkers in good conditions.
Starting from Rhyd Ddu, the route begins with a gentle walk through forest, offering shelter and a gradual introduction before the climb begins in earnest. As the path leaves the trees, the landscape opens out and the sense of space quickly grows.
The ascent of Mynydd Mawr is straightforward but persistent, with the effort rewarded by expanding views throughout the climb. Yr Wyddfa, Moel Eilio, Yr Aran, and the Nantlle Ridge all come into view, giving a clear sense of Snowdonia’s scale and variety.
At the summit, the panorama is particularly impressive. On clear days, views stretch across the Menai Strait towards Anglesey and Caernarfon, with Snowdon filling the skyline to the east and the Nantlle Ridge stretching away to the south.
The return follows the same route back to Rhyd Ddu, allowing time to enjoy the changing light and perspectives on the descent. With its combination of forest, open mountain, and expansive views, this walk offers a satisfying and less crowded alternative to Snowdon’s main paths.
“This is probably the walk we’ve done the most ourselves — and the reason is simple. It’s quiet, the path is straightforward, and the views across the Menai Strait towards Anglesey from the summit are uninterrupted in a way you don’t get from busier peaks. On a clear day it’s hard to beat.” — Delyth, Perthi Holiday Cottages
