Hen Mountain is one of the less challenging climbs of the Mourne Mountain range, not to worry though, as it still provides the stunning panoramic views that the Mournes are so good at showcasing. There are a few rocky outcrops up here which can be discovered and explored, just do watch your footing as you move about.
