Park on section of disused road next to Benlettery youth hostel (778483 F). Walk up road to youth hostel and take a stile to the left onto the hillside. Pass through a stand of trees and cross a fence. There follows a steep climb of over 500m on generally good ground. There are great views down over Ballynahinch Lake (can pick out the elusive castle) and many other loughs before the sea. There is a well trodden track (eroded) as hit the higher reaches of the mountain, marked by some small cairns. The ground here is increasingly rocky and i have had difficulty on 2 occasions before the summit with steep ground requiring the use of hands - where is the easier path?
The summit is mostly rocky with a few cairns. There are wide reaching views - west over Benglenisky and to the islands of the Atlantic, east to the other side of the famous Glencoaghan horseshoe and the Mamturks, north to the impressively rocky top of Bengower backed by Benbreen and of course south to the loughs and loughs and sea.
A good starting point for one of the best walks in the country around Glencoaghan, or a visit to Bengower and Benglenisky. Can be busy but today no one else which made it all the better. Linkback: https://mountainviews.ie/summit/315/comment/3180/
