Did You Know?

• •The hill was a vital source of manganese, heavily mined during the World Wars to harden British steel. You can still trace the ghost of the old tramway that once hauled ore down to the sea.
• •Archaeologists discovered a Neolithic axe factory on the eastern slopes, proving the locals have been manufacturing tools here for millennia. It seems the Llŷn Peninsula was a high-tech industrial hub long before the invention of the wheel.
• •The summit offers an unparalleled view of Porth Neigwl, also known as Hell’s Mouth due to its legendary status as a ship-swallower. It is a stunning sight, provided you aren't currently trying to navigate a 19th-century schooner.
• •At the foot of the hill lies Plas yn Rhiw, a manor house restored by three sisters who were effectively the original environmental activists. They bought the land to stop it from being developed, proving that a well-placed inheritance is the best defense against urban sprawl.
• •At 304 meters, it is a 'mountain' in the same way a cupcake is a 'balanced meal'—technically true but largely optimistic. The wind, however, takes its job very seriously and will attempt to blow your sandwich into the next county.
