    Cnoc na hUilleann, or Knocknahillion, which is 607 metres high, is a gem of a mountain in the central Maumturks area. It is not that high, but it is big in attitude, and if you follow the spectacular undulating ridge north, you will reach the slightly higher point of Letterbreckaun, which is 667 metres high.  On the way you will be able to take in the stunning views of the 12 Bens and the beautiful Lough Inagh Valley.
