The Great Sugarloaf (Ó Cualann also Beannach Mhór) is 4km west of Kilmacanogue, Co Wicklow and is set apart from the Wicklow Mountains, with its conical shape and broody demeanour the Great Sugar Loaf makes an instant impression. It's barely 501 metres tall, but this plucky hill is one of Ireland's most iconic peaks. The Sugar Loaf may have the appearance of an extinct volcano; it is in contrast to the granite mountains to the south and west, a quartzite hill.
On a clear day you can see not only Dublin City and the Wicklow Mountains, but Snowdonia in Wales. It's hugely popular outing for Dublin day trippers. If you're reasonably fit and don't mind a bit of scrambling on the rocky final stretch, you can be up and back from the summit in little over an hour (access is to the south along the L1031).
