The combination of sunlight and sandstone gives off a breath-taking purple hue, which makes this summit an absolute feast for the eyes and certainly one of the most beautiful Irish mountains.

Less a mountain and more a mountain range, the Twelve Pins (a.k.a. the Twelve Bens) are one of the most stunning land formations in Ireland. This range is made up of over 22 stunning peaks, all so magnificent, it was impossible for us to choose just one!

At the centre stands Benbaun at 729 metres (2,392 feet). While the Pins are not the highest mountain range in Ireland, their prominence and rugged ridges in contrast with the surrounding landscape give them an amazing dreamlike quality.

This distinctive flat-topped formation stands at 526 metres (1,726 feet) and dominates the Sligo landscape with such majesty that it is no wonder it is the setting of several Irish legends!

It is known to have been the ancient location of the legendary Fianna’s hunting grounds! Also associated with Benbulben is the famous tale of the “Pursuit of Diarmuid and Gráinne,” and it is said that the mountain is the location of their final resting place.
