Camlough Lake is picturesquely nestled between the rolling hills of Slieve Gullion and the Ring of Gullion. Cycling along the narrow roads on the shore, you immediately feel the tranquility that emanates from the long stretch of water. The lake stretches for more than two kilometers and seems like a narrow, silent crack in the landscape - a peaceful place to take a short break or let your gaze wander over the water. I decided to take a little detour and cycled a little closer to the shore on a path. The water was almost still and reflected the range of hills that rise in the background. It may be a paradise for fishermen, but cyclists also enjoy the special atmosphere. The roads around the lake are not very busy and you can cycle in a relaxed manner without having to constantly pay attention to the traffic. One small criticism: some of the access roads are not well signposted, but if you look around a bit, you'll surely find a good place to get to the shore and enjoy the scenery.

Along Glasdrumman Lough you walk along a calm body of water surrounded by green hills. The lake lies still and reflects the blue sky while the gentle waves break the sunlight. On one side of the road there is a sign telling you about the Poets' Trail - a hiking trail that shares not only the nature but also the history of this region with you. The information board tells you about the nearby O'Neill Castle, of which only ruins remain today. Here you can immerse yourself in the world of old Irish poems and legends that have their place along this trail. It is a place where nature and culture meet.

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.

Camlough Lake The often calm, tranquil waters of Cam Lough stretch for just over two kilometers in a north-west to south-east direction. This narrow, elongate lough provides rich waters for the fisherman and marks a break in the lines of hills that surround Slieve Gullion, the Ring of Gullion.
