I accessed this hill coming from Knocklettercuss. The terrain in-between the two hills was mostly dry and easy going.
The narrow line of forest I had to go through to get to the top of Sheean was no bother to walk through as the trees here were sparse with plenty of gaps. 895198 C The top is relatively flat and has no cairn. The biggest mistake I made was on my decent straight towards Briska were I tried to go through the forest at 893205 D. There is a tempting gap here going in a northeasterly direction towards the rivers and track , but the trees only get denser the further down you go. At times I had to get down on my hands and knees and crawl my way through. Eventually I saw light through the trees and reached the narrow river tributary ,very close to where it joins the much larger Owenmore river. I then followed the track out.
