Mynydd y Garn

Mynydd y Garn is a 170-meter-high hill on Isle of Anglesey topped with a stone obelisk and trig point at its summit. The vantage point offers expansive views across the northwestern portions of the island.

Local residents erected the stone obelisk at the summit in 1897 to honor Sir William Thomas, a ship owner and High Sheriff of Anglesey. This monument reflects the historical links between the local community and its prominent figures.

The Welsh name Mynydd y Garn means "hill of the cairn" and refers to stone heaps that historically marked this location. Locals have long used such features to navigate the landscape and understand the terrain.

Public footpaths access the western slopes, while a permissive path connects from a minor road directly to the National Trust-owned summit. The route is relatively straightforward for visitors with moderate fitness levels.

The summit displays distinctive Ordovician sandstone that contrasts clearly with the schists found on the southern slopes. These geological differences reveal the layered rock composition that shapes the island.
