Using the extensive forest tracks, I had planned to do a 4-carn loop taking in Cullaun and the three Slieve Felims. I started at R83875 57275 D, bagged Cullaun in about 20 minutes and returned to the track at R 824 572 E. Here the problems began. What looks on the map like a nice track leading all the way to Slieve Felim East top turned out to be little more that a river of mud for its entire length. It was utterly impassible in places, requiring me to retreat to either the adjacent heathery bog (almost as bad) or to beat my way through the woods. The 3 km walk took me 80 minutes of unpleasantness, the only relief being an occasional frozen section (as in pic). The high point is a clump of slightly elevated heather with an ancient tree branch stuck in it. Definitely a baggers' hill. Linkback: https://mountainviews.ie/summit/1057/comment/23409/
