In the middle of the forest, you suddenly find yourself standing in front of a bizarre stone creature - the "witch". She looks as if she has just risen from the mossy ground, with a mischievous smile and deep, expressive wrinkles on her face. This artfully designed stone is one of those unexpected encounters that transform the forest into a small adventure land. When you explore this magical place surrounded by old trees and whispering leaves, it almost seems as if the witch is greeting you with a wink. Here you can linger for a moment, enjoy the silence and let your imagination run wild - who knows what stories this forest still has to tell?

As soon as you cross the gentle ridge of Slieve Gullion, the North Cairn stretches out before you - a slightly smaller hill than its southern neighbour, but no less impressive. The stones that gather here seem like silent sentinels, witnesses of the distant Bronze Age. Two ancient stone boxes were once found here during excavations, which lay hidden in the depths of history. The North Cairn, with its diameter of around 18 metres, invites you to pause for a moment and enjoy the peace. But it is not just the Cairn that is fascinating. Right next to it lies "Calliagh Beara's Lough", a quiet mountain lake that, according to legend, is the home of the witch Beara. On a clear day, the sky is reflected in the calm waters and you can almost feel the ancient magic of this place coming to life. The road here may be rocky, but the landscape rewards with sweeping views and a touch of mysticism that makes Slieve Gullion something special.

The site can trace its roots back to the 6th century when a monastery for nuns was founded by St. Moninna. The ruins of the two joined churches that can still be seen date from the 11th and the 15th century. Look for the large slab which is said to be St Moninna's grave.
