Mynydd y Garn

Mynydd y Garn is a hill in the northwest of the Isle of Anglesey in north Wales. Its summit rises 170 metres above the surrounding land and is marked by a trig point and a stone obelisk. The obelisk was put up in 1897 to honour Sir William Thomas, a local ship-owner who once served as High Sheriff of Anglesey. The hill’s geology shows Ordovician sandstone at the top and Gwna Group schists on the southern slopes. Below these lie New Harbour Group schists and psammites, while the lower ground around the hill is covered in glacial till. The hill itself has no such superficial deposits, leaving its bedrock exposed. The hill is worth visiting for its open access and clear views across Anglesey. The National Trust owns the summit area, allowing free public access on foot. Two public footpaths cross the western slopes, while a short permissive path leads from a minor road on the west side to the summit. The contrast between the exposed bedrock and the surrounding glacial till makes the geology easy to see. The obelisk and trig point provide landmarks for walkers aiming for the top. The views from the summit stretch over the island’s varied landscape. Visitors find a simple grassy summit with the obelisk and trig point standing on bare rock. The minor road to the west provides the easiest starting point for the short climb. The public footpaths on the western slopes offer gentle routes up the hill. From the top, wide views take in the surrounding countryside and coastline. The exposed rock and clear paths make the walk straightforward. The hill’s modest height still rewards climbers with a sense of achievement and fine scenery.
