Start from the forest entrance at W66873 95524 A and follow the track, ignore the first right after a hundred meters or so and keep on due south . This track then begins to head north east, ignore the next right and take the right that follows it to find the fenced off summit area crowned by 3 masts. The actual highpoint is in a small clearing just beyond the most NE mast. It is a slightly raised area and next to it are the remains of what is possibly a small megalithic structure.

There is good access to this summit from a reasonable marked loop walk starting at the graveyard south of Killavullen. Following the marked trail is 13.6km (about 2.5hrs), but you can take a more direct route if you want. The best way to the summit is via the road up to the masts, go around behind the fence at the highest mast and duck through the tree to the mossy summit mound, pretty dull and un-interesting but nice and sheltered for a bit of lunch.

The little hill of Corran is probably best viewed from a distance.
Its summit is covered in woods and blighted by no less than 3 masts, but this does mean it is easy to reach from the road W66873 95524 A by means of forest tracks.
It does however overlook two places of note.
The first is the townland of Ballygriffin which is the birthplace of the founder of Presentation sisters Nano Nagle. She brought solice to the poor of Cork in the 18th century.Her family farm is now the location of a retreat centre and organic farm
Nearby in the village of Killavullen is the birthplace Richard Hennessy who was born in Ballymacmoy House . He also brought solice to the people of Cork .He went to France in 1740 and became an officer in Dillon's Irish Regiment in the French Army. In 1765, he went to the Charente departement and set up the distillery that produces Hennessy brandy. The distillery continues to this day, as does the Hennessy line in the company. The Hennessy house at Killavullen overlooking the river Blackwater, can still be seen today.
A poem by Raphael Consedine says of the Nagle Mountains,
"The blossoming hedgerows sang freedom,
The river told stories of places far away,
While beyond, dreaming mountains called." Linkback: https://mountainviews.ie/summit/793/comment/2810/
