Parked up near the bridge on the Carn - Buncrana Road. Followed the path up until it veered off then left the path (rough road for dragging turf) to get onto the mountain. Rises fairly steeply then flattens out into a kind of plateau before rising again (kind of a two peak thing going on). There is a ring of stones at the top which is a good spot for shelter if you take a break. If you are lucky enough to get a clear day, it is a nice walk with stunning views. Harder than it looks though.
