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.

Not the biggest in the mournes at only 472m but well worth the climb as the views from Slievemeen are incredible! A great walk for kids as it's relatively close to the car park and has a nice summit to take a picnic on.
