A tough walk mainly due to the terrain, which was very rough in parts, of about 7km with an ascent of about 600m.The first section, on the lower slopes of Barnes Top, was relatively easy going – mostly grass, some heather and marshy in parts. Nearing the top, the heather takes over, making for energy-sapping progress to the dull top, which is unmarked.The only saving graces were the beautiful weather and some good views of the surrounding landscape. I then descended to the col through more heather, with only a faint track appearing once in a while – the fact that the ground was frozen helped, and I imagine that in milder conditions the ground would be very slippery.The col was quite marshy and requires crossing a couple of barbed wire fences. I then began the ascent up Mullaghash. The vegetation on the southern slope differs from that of Barnes – it is clumpy grass mostly, the clumps quite close together, which requires more weaving about and leg-lifting. The slope is also quite steep, making the ascent quite challenging.The summit area, like Barnes Top is heather-covered and unmarked, although there is a large boulder about 10m from the high point. I then returned the same way, which of course required me to make another, wearying ascent of Barnes Top. Overall, some ok views and 2 more ticked off, but I won’t be back.
