Slieve Lamagan stands in the middle of the high Eastern Mournes, overlooking Ben Crom Reservoir to the west, Annalong River valley to the east, and Cove Mountain to the northeast. At its southern foot is a small lake called Blue Lough, and a rock formation known as 'Percy Bysshe' .
It is said that the mountain was named Sliabh Lámhagáin, "mountain of crawling/creeping", because its steepness meant it had to be climbed in a crawling position. An older name was Slieve Snavan, from Sliabh Snámháin, which has the same meaning.
