Benlettery mountain or ‘Binn Leitrí’ in Irish meaning ‘peak of the wet hillsides’, is the 343rd highest summit in Ireland and the most southerly peak of the Twelve Bens.
An alternative name for the mountain is Bindowglass or Bendouglas (Binn Dúghlais in Irish, ‘peak of the black stream’) has been recorded as early as 1684 by Roderic O’Flaherty. It’s notable that in both names, they both refer to the wet state of the mountain. O’Flaherty further mentions a pool of water on the summit which turns the hair white of anyone who washes in it.
The peak of the mountain measures to a height of 577 metres (1,893 ft).
