Keelogyboy Far East is a fairly narrow NS ridge with the steep sides so characteristic of the limestone of the area. There's great views of Lough Gill and the wooded Doons to the south.
One way of reaching it is from the east and Leann Mountain via the northern slopes of the low hill of Fawnion. It is also possible to park at G7668 4012 A and follow a farm track into the valley. Head to the right of Hangman's Hill and contour around Keelogyboy Mountain NE Top. There is a sharp pull up to Keelogyboy Far E Top, and you shouldn't go too far before heading up as the slopes become cliffs further south.
The South and SW of this summit is a serious cliff. The top is covered in heather with a track leading from the north to the highest point towards the south, near which there is a substantial, narrow cairn. Linkback: https://mountainviews.ie/summit/742/comment/5501/
