Popular around Lough Muckno
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.

Here, a bull sits, seemingly rising from the ground, sleeping contentedly. The stone is said to be connected to the legend of St. Patrick, who was once teased by his pet bull while building his church. Whether or not this was true, the story lends an air of mysticism to the place. The surroundings are quiet, and there is a small bench where you can rest while you reflect on the legends and myths that surround this place. The art installation is not necessarily a major highlight, but it adds an interesting touch to the landscape and gives your tour a small, unexpected detail. The road here is easy to ride, with only a few small inclines, so if you have time for a quick stop, this is a nice place to take a break and prepare for the next leg.

The Tassagh Viaduct rises above the Callan River Valley with its massive arches - a silent witness to bygone railway times. The line, which was originally part of the Castleblayney, Keady and Armagh Railway, opened in 1910 and once carried trains across the valley. Today the tracks have disappeared, but the impressive structure remains and blends beautifully into the green landscape. As I drove under the arches, I felt like I was experiencing a piece of history up close. Looking up at the imposing stone arches makes you pause for a moment and marvel. The old Beetling Mill is also nearby, a reminder of the region's industrial past. If you have a bit of time, a little detour there is worth it. The roads in the area are mostly in good condition, but there are also a few bumpy spots - nothing that will bother an experienced cyclist. Overall, a worthwhile stop that will appeal to more than just railway enthusiasts.

There are great views of Newry City, The Mourne Mountains, Carlingford Lough and The Cooley Moiuntains from up here. Flags were raised here to announce arriving boats coming into the lough, hence the name Flagstaff.

With grounds overlooking Lough Muckno, Hope Castle has been abandoned since 2010 when a fire ripped through the interior. At that time it was a hotel but it was originally built in the 17th century as part of the Blayney family's estate.
