In Ireland there are 269 mountain summits that are 600 metres or higher, and with a prominence of 15 metres or more. These are The Vandeleur-Lynams. And there are 404 summits with an elevation of at least 500 metres, with a prominence of 30 metres or more. We call these The Arderins.

For the first time both these lists are published together, along with lists of Ireland’s 27 County Highpoints and the island’s Hundred Highest mountains, using updated data and information as contributed by the MountainViews.ie community. This book will undoubtedly prove to be an invaluable resource for the peak-bagger, summiteer and hillwalker alike.
