About Moel-yr-hydd
A sturdy Moelwynion outlier that formally resides in the 'hole' of the Snowdonia National Park, Moel-yr-hydd is more industrial relic than pristine wilderness. It's the kind of peak that rewards those who enjoy walking over hollowed-out slate chambers while pretending they aren't about to disappear into a Victorian mine shaft.

Did You Know?
- •The Wrysgan Quarry operated on the north-east flank for over a century, carving massive underground chambers directly beneath the summit. It’s essentially a giant, slate-flavoured Swiss cheese with a mountain on top.
- •The mountain is famously part of the Snowdonia 'hole,' a section of land excluded from the National Park to keep the industrial scarring of Blaenau Ffestiniog separate from the tourist-friendly bits. It's the rebel of the Moelwyns.
- •Its name translates to 'Hill of the Stag,' which is somewhat optimistic given the current local wildlife. You are significantly more likely to find a hardy Welsh mountain sheep staring you down than a majestic deer.
- •The ascent from Tanygrisiau follows the old quarry inclines, providing a steep but fascinating lesson in Victorian engineering. It’s the perfect climb for hikers who prefer their nature with a side of heavy industrial archaeology.
- •While guidebooks claim the summit is easily reached from the railway station, they often forget to mention the terrain's uncanny ability to turn into a sponge. Expect to finish your 'easy' walk with boots that weigh three times more than when you started.
