Ireland's 100 Highest Mountains

This list of Ireland's highest mountain summits has been 100% derived from the Irish Hewitts. The acronym term "Hewitt" refers to any Hill in England, Wales or Ireland over Two Thousand feet above sea level. In addition, a Hewitt must also have a prominence of at least 30 metres. This matches the official definition of a mountain in Ireland. This page focuses on the 100 highest Hewitts / mountains in Ireland as originally listed by the late E.D. ‘Clem’ Clements.
​
Since E.D. ‘Clem’ Clements’ death a Legacy Committee has been formed to safeguard all his hill related documents, which also include his hill lists, with the co-custodian responsibility for the Irish Hewitts now being with Myrddyn Phillips and David Purchase.

We would like to thank Myrddyn and David for agreeing the inclusion of Clem's list on The Ireland Walking Guide website and for supporting the creation of this hillwalking challenge.

Mountain and hill summits offer great walking opportunities all year round, however we particularly recommend visiting them during months when the days are longest. For this reason, we promote upland walking as our monthly theme for June.

Support us (at no cost)

Our website is a 100% free resource for all to view without having to pay any subscription fees or being asked for donations. We cover all the costs of running and maintaining the website ourselves on a voluntary basis. And we do all of this purely for our love of walking in Ireland. The long-term development strategy for The Ireland Walking Guide website will continue to be implemented over the coming years and for as long as it takes until our strategic goals are achieved. In the meantime, here are some zero-cost, zero-time ways in which you can support the ongoing development of The Ireland Walking Guide and its growing family of independent Irish information websites.
​

Walking initiatives

We have developed the widest possible selection of meaningful initiatives to promote recreational walking in Ireland. These are delivered across The Ireland Walking Guide and High Point Ireland websites and range from monthly walking themes right through to the official All-Ireland Hillwalking Championships. We aim to deliver a consistent programme of initiatives every year on a recurring basis rather than a series of standalone one-off campaigns. Our "predictable" approach to participation initiatives means walkers always know what's coming up and have ample time to plan ahead. But why should you take part? Click here to find out...
