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.

This historic 10th century tower stands in idyllic countryside and offers a fascinating insight into Ireland's early Christian history. Access is via narrow country lanes; there is a small car park but it is not always well signposted. The tower is on private farmland but access is usually permitted.

The route takes you along the Silent Valley Reservoir on a well-developed, asphalt road that is also suitable for less experienced drivers. However, it can be slippery in wet weather, so caution is advised. A special highlight is the impressive dam wall of the Ben Crom Reservoir, which blends harmoniously into the surrounding mountain landscape. Please note, however, that access to the park is subject to a fee.

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 narrow path winds through dense ferns and forests, and you can literally feel the silence around you - only the crunching of the tires on the gravel accompanies you.

Suddenly this ancient monolith rises before you, a silent witness to times gone by and myths. It stands alone on the green meadow, surrounded by a peaceful, almost mysterious silence.

Dating back to the 19th century, this historic port offers an authentic insight into the region's maritime history. The well-maintained paths along the port make for a pleasant ride with views of the Mourne Mountains in the background. However, it can get slippery in wet weather, so care must be taken. A particular highlight is the Annalong Cornmill, a restored watermill that is well worth a visit. Nearby you'll find the Harbour Inn, a cosy eatery known for its fresh seafood. Note, however, that the harbour can dry out at low tide, which changes the view.

The sea stretches out wide and sparkling, and the light smell of salt in the air gives you a feeling of freedom. The waves break gently on the rocks, and the view of the endless blue is hypnotic.
