Up and down to Tievecrom - one of the more unpleasant walks I have had. Massed briars and brambles resist you all the way and you seem to be fighting for every foot.
That being said, if you need to do it, this track will get you there - I suggest following my descent rather than ascent might be best - maybe it was only because I was going downhill, but the descent seemed clearer of growth.
The track starts from a rough parking space opposite the locked gate to a lane (gate on left). Further up the lane was blocked by cattle and I dropped into a field to detour around them - it appears that the fields either side of the lane are gateless and cattle wander freely between them.
