Benbulbin,sometimes spelled Ben Bulben or Benbulben (from the Irish: Binn Ghulbain), is a large flat-topped rock formation in County Sligo, Ireland. It is part of the Dartry Mountains, in an area sometimes called "Yeats Country.
A hard and resistant limestone forms the upper cliffs and precipices. Benbulben was formed during the Ice age, when large parts of the earth were under glaciers.Benbulben hosts a unique variety of plants, possessing some organisms found nowhere else in Ireland. Many are artic alpine plants, due to the mountain’s height, which allows for cooler temperatures than is normal. These plants were deposited when the glaciers that created Benbulben melted. Insects, hares and foxes inhabit Benbulben.
It is possible to climb Benbulben as there is a looped access trail but it is strongly advised that you have a guide to hike Benbulben
