A longish, fairly challenging loop that takes in five Carns, involving a lot of up and down. Parking for a single car at the start point. Continued along the track and went through gate, where track deteriorates into a barely noticeable grassy trail.Continued across a gently rising boggy area, but not too bad, for about 1.5km, heading for the more pointed spur to the left and then swung more to the east, where incline increased. Fairly easy climb up Hangman’s to unmarked top with great views.Dropped down to about 290m to the south before beginning the only really steep ascent of the day up the NW flank of Keelogyboy Far E Top. Another unmarked top (although a cairn nearby) but with wonderful views of Lough Gill to the south.Made a careful descent the way I’d come (at one point sliding down the grassy slope on my backside) and crossed the valley to the west, the 3km journey to the next top sometimes over rough ground – heather and uneven in parts. Dropping down to the col just before Keelogyboy SW Top, you only have a 70m climb, but unfortunately it is over heather, which makes it that bit tougher. The summit is a relatively small area, unmarked, covered in short heather and grass, but with fine views of the impressive western face of Keelogyboy.Three down, two to go, I returned to the col and turned north up a fairly easy, grassy slope to reach the summit of Keelogyboy itself, the only marker I could find a single small rock atop a heathery rise, but with great views of the northern side of the SW Top. Dropped east to yet another col, followed a grassy track for about 200m up to the southern flank, then turned north, crossing some fascinating geological limestone areas typical of the Dartrys.My fifth Carn was also unmarked, and the highpoint is to the west of a large area of unusual rocky outcrops. Dropped down north and picked up a farm track at about 350m, which took me all the way back to the start point. Overall a tough, but very rewarding day.
