Slieve Loughshannagh is one of the quieter summits in the Mourne Mountains, but it rewards hikers with wide, open views over Silent Valley, Slieve Binnian, and the western Mournes. The climb isn’t too demanding, and the summit has a peaceful, windswept feel, making it a lovely spot to pause and take in the rugged beauty of the landscape.

Silent Valley Reservoir, nestled in the Mourne Mountains, is a peaceful retreat surrounded by sweeping granite peaks and heathered slopes. Built in the early 20th century to supply water to Belfast and much of County Down, the reservoir combines striking engineering with natural beauty. Visitors can stroll along well-kept paths, admire the Victorian-style dam and impressive Mourne Wall, or simply enjoy the quiet atmosphere by the lakeshore.

Victoria Park in Belfast is an interesting spot for a short bike ride and a break by the water. It is accessible 24 hours a day and has a quiet lake that is enlivened by swans, ducks and other water birds. The walk around the lake is particularly relaxing, where gently curved paths lead you through the greenery of the park. The complex dates back to 1906 and was designed by landscape architect Charles McKimm, who also designed the impressive tropical hall in the Botanical Garden. You can also explore the small BMX track by bike, which attracts ambitious cyclists - perfect for adding a little variety. On the banks of the lake, the complex offers a beautiful mix of nature and urban flair. Free parking makes access uncomplicated and practical. A walk or a bike ride through this historic park is a refreshing break, especially with the lively birdsong and the proximity to the water. Whether for a short break or a longer stay – Victoria Park offers a pleasant ambience in the middle of the city.

The well-maintained trails take you through impressive scenery, surrounded by the striking peaks of the Mournes. The view of the Mourne Wall, which stretches for 35 kilometers and connects 15 peaks, is particularly impressive. However, some sections can become slippery in wet weather, so caution is advised. A highlight is a visit to Ben Crom Reservoir, which can be reached via an extension of the route. Note that there is a fee to enter the park.

The Maghery Footbridge on the edge of Lough Neagh offers a small moment of peace in the midst of the expansive landscape. As you cross the bridge, your gaze glides over the gentle waters of the largest lake in the British Isles. In good weather, the clouds are impressively reflected on the surface of the water, making the scene look almost like a painting. Even when the sky is cloudy, the lake has a special atmosphere that invites you to linger rather than to quickly pass by. The paths around the bridge are mostly flat, but you should be prepared for occasional sections with unpaved surfaces. This could be a bit slippery, especially in wet weather, but this is not a problem. The connection to the National Cycle Network, Route 94, also offers you many other opportunities to explore the area. A little tip: Maghery itself does not have much to offer apart from the bridge, but a short detour to the nearby Oxford Island nature reserve is definitely worth it. This means you can easily combine a visit to the bridge with a larger circular tour.

The paths are wide and perfect for families, as there are no cars to disturb you. As you glide along the car-free cycling and hiking trails, you can enjoy the view of the water - especially when the sky is cloudy, the lake has a very special atmosphere, almost mystical. The route is mostly asphalt, but there are also some gravel sections that provide some variety. These single-track paths add a certain challenge to the route without being really demanding. Ideal if you prefer to take it easy, but still don't want to just walk on smooth asphalt. If you want to take a break, the lake offers many corners to catch your breath and have a picnic. There is enough space on the banks to rest a bit and enjoy the surroundings to the fullest.

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.

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.
