During your ride through the Seatown district, you cannot miss this imposing stone tower. The Seatown Windmill, built around 1800, was once one of the tallest windmills in Ireland with its eight floors. Although the sails have long since disappeared, the robust hull remains an impressive monument to the city's industrial past.

The dam is easy to cross and from there you have a great view over the lake and the rolling hills that surround it. The peaceful atmosphere is only occasionally interrupted by the gentle rippling of the water. The reservoir provides fresh drinking water to the surrounding area and the trout fishery here is controlled by the Armagh Angling Club - so it's an interesting spot for anglers. Even if you're not here to fish, the scenery is simply relaxing and it's worth stopping for a few minutes and looking around. The roads around the lake are easy to drive on but there might be a few potholes in places - nothing that would stop a real cyclist. Overall a nice stop to enjoy nature and take a quick breather before moving on.

If you need a relaxing break on your tour of the region, Basil Sheils Bar and Restaurant is a perfect place to unwind for a moment. The colorful building, surrounded by green trees and colorful flags, immediately catches the eye. A beer garden invites you to reward yourself with a cold drink and a little refreshment for the next stage. I treated myself to a break here after a long ride and enjoyed the rustic ambience. In the courtyard, also called "The Forge", there is a restaurant with rustic food - ideal if you get a little hungry. The atmosphere is relaxed and the people here are friendly, which makes you feel welcome. In addition, overnight accommodation is offered if you want to treat yourself to a little more relaxation after a long day on the bike. It could be a little tidier in some places, but that also gives the place its charming, slightly chaotic character. A cozy stop to recharge your batteries before hitting the road again.

The Craigmore Viaduct is an impressive structure, with its 18 arches spanning the Camlough River Valley, dominating the landscape of south Armagh. As I cycled along the gently curving roads, the viaduct suddenly appeared on the horizon - a massive but elegant sight. The tall stone arches seem to effortlessly support the train traffic that runs between Dublin and Belfast. I stopped for a moment to take a closer look at the structure. It is fascinating to know that this structure has been standing here since 1852, designed by Irish engineer John Benjamin Macneill. The highest arch rises 126 feet, and standing under it you can really appreciate the scale and importance of this structure to the region. The surroundings are just perfect for putting your bike down and taking some time to look at the view. Perhaps a small lookout point with information about the history of the viaduct would be a nice addition, but even without it it is a worthwhile stop along the way. We continue, but the image of the arches remains in our minds.

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.

The old walls of the two joined churches stand still and weathered amidst tall trees - you can almost feel the history in the air here. It is amazing that the roots of this place go back to the 6th century, when Saint Moninna founded a nunnery here. Today, the ruins from the 11th and 15th centuries still stand, and although much has fallen into disrepair, the remains give a sense of calm and past. A special detail is the large stone slab that is believed to be the tomb of Saint Moninna. It is a little hidden, but if you look for it, you will definitely find it. The old cemetery setting with the Celtic crosses and weathered gravestones adds to the mood. For me, it was a pleasant break from the ride. Here you can sit back for a few minutes, park your bikes and just soak up the atmosphere. It is one of those places that does not scream loudly for attention, but tells its stories in silence

Derrymore House has been built in the 18th century by MP Isaac Corry. It has been built in the style of a cottage and less of a manor and therefore nicely fits into the green and lush countryside. Today the building is owned by National Trust. The park around Derrymore House is open to public all year round, while the so called Treaty or Drawing room in the house itself only opens at certain times.
