The Coumshingaun hike is not one of the most straightforward and easy hikes in Ireland; it's in fact considered, and it is indeed, hard at a point that in some places it also gets very challenging. You need to scramble over some rocks, hence you need to be fitness-ready, wear good hiking boots, and having a sense of direction because in some areas it is easy to get lost. This isn’t a walk for inexperienced hikers, nor one to be taken lightly.
