Druid’s Circle, Clermont Estate: this small oval stone circle above the Flurry River, marked as both “Standing Stone” and “Druids Circle” on old maps, was likely uncovered in 1840 by Lord Clermont. Though some believe it’s prehistoric, others argue it may be 19th-century landscaping. Its irregular layout and re-set stones cast doubt on its authenticity. Still, it’s a scenic and mysterious woodland stop.

The Long Woman's Grave car park is right at the top of a gentle climb, giving you the perfect opportunity to take in the rolling landscape. Whether you're coming from the north or the south, the roads take you through varied terrain that reveals new panoramas with every bend. It's worth taking a moment to read the story of the "Long Woman" at the memorial - somehow this mystical atmosphere fits perfectly into the surroundings. On the way up, you hardly encounter any traffic, which allows you to fully concentrate on nature and your own line in the bends. The fresh breeze and the smell of damp grass add a little extra to the climb. But the roads are not always in the best condition - some sections do require attention, especially after a rain shower. Once you reach the summit, there is a small rest area, ideal for taking a quick breather and regaining strength for the next stage. A perfect spot to take a short break before continuing with renewed vigor.

The hike to the Cloghmór Stone feels like a journey through time. Over 10,000 years ago, the ice brought this massive granite block from Scotland here, and now, weighing an estimated 50 tons, it towers majestically over the landscape. But it's not just the geology that's fascinating - according to legend, it was the giant Finn McCool who threw this enormous stone over Carlingford Lough. To be honest, the legend is a much more exciting explanation, isn't it? Once you've reached the top, you'll not only be greeted by the imposing boulder, but also by a fantastic view of Carlingford Lough and the surrounding hills. It's the perfect place to pause for a moment, take in the vastness and enjoy the peace that this place exudes.

Hidden in Ravensdale Forest, off the main paths, you come across a mystical stone circle that raises questions: Was it the Druids who held their mysterious rituals here, or was it the eccentric 19th century landowner who wanted to immortalize himself with this project? Nobody knows for sure, and that makes this place all the more fascinating. The eight stones, arranged in an oval, seem like silent witnesses to a time long gone. On the maps, the circle is referred to as both the 'Standing Stone' and the 'Druids Circle', and you immediately sense that this place exudes a special aura. The stone circle is just a short climb from the Flurry River, in the middle of the old Lord Clermont Estate. Up here, in the shade of the trees, it feels like you have entered another world. The stones, covered in moss, invite you to pause and enjoy the tranquility of the forest.

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.
