A route from the north starts at the northern end of Glenbeg Lough V70103 53800 A and following the track there.
A route from the south starts from by leaving your car at Rosmackowen Church V74200 47209 B (Point A) and head up the little borheen immediately after the Church on the Castletownbere side.
Take the left hand fork after a few hundred meters and continue on through a gate following a rough track to the Glas Loughs at about 400 meters elevation.
The face of Knocknagree that looks out over Beara Island is the best approach to take with the least amount of climbing around the rocky folds typical of the area.
Down the rough far side then to a small lake followed by a boggy trot across peat hags and one small hill before the climb to Lackawee's summit.
The view of the Iveragh peninsula on a good day is exceptional. Linkback: https://mountainviews.ie/summit/323/comment/5083/

I walked down the long ,broad back of Maulin and crossed over point 579mtrs before reaching the rounded hump of Lackawee.There are several turf banks to be avoided on the way and again the ground seemed very wet in places. This is a great vantage point from which to view the Beara peninsula ,on a clear day is you can see it from the tip all the way back to the Sugarloaf over Glengarriff. In the distance to the north I could make out the 'Reeks quite clearly The photo is taken fom the north side of Maulin with Lackawee on the left and point 597mtrs in the near distance.
From Lackawee I retraced my steps to the lake on the col under Knocknagree and then skirted around to reach the track at approx 410 mtrs back down to Rosmackowen Church. 5.5 hours and 16.5 kms Linkback: https://mountainviews.ie/summit/323/comment/1791/

This track at the northern end of Glenbeg Lough provides easy access for an ascent of Lackawee, clearly visible on this beautiful day in May. There is also enough space at this point to park several cars. The gated track leads to some sort of official looking building which appears to be related to the lake in some way (water monitoring/fisheries/ who knows?) but was unmanned when we passed. Just beyond the building, access to the lower slopes of Lackawee is easy and on a day like the one we enjoyed, the view back down to Glenbeg Lough was stunning.
