Merrick is by no means an easy climb, particularly in Winter. The start of the trail is extremely boggy, with submerged sections, steep rock-covered portions, and many other dangers. Once past the Culsharg bothy, there is another steep and treacherous section through the forest up to the deer fence, where there is a half-way decent path, but you will be buffeted by gale-force winds all the way up to Benyellary. The ridge from there to the summit of Merrick is long, exposed, and steep, with the wind blowing from your right on the way up.

My friend and I nearly had to turn back due to fading light. Boab is an idiot. Disregard what they have written. Merrick is dangerous, especially in Winter.
