Navan Fort, also known as Emain Macha, is one of those places that literally breathes history. As a cyclist, you can feel a breath of the past here as you roll gently over the grassy hills. The site, rich in Neolithic, Bronze Age and Iron Age finds, is not only archaeologically fascinating, but also firmly embedded in Irish mythology. The kings of Ulster are said to have ruled here, and the legends of Macha, the namesake, are omnipresent. The gentle climbs around the fort are not too demanding, but give you space to let your gaze wander over the green hills - particularly dramatic when dark clouds pile up in the sky and cast a mystical atmosphere over the landscape. A detour to the visitor center is worthwhile: Here you can find out more about the exciting stories and the excavations that provide insight into Ireland's deepest 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.

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.

The impressive property tells stories of a time when the Earls of Gosford ruled these green lands. The renowned London architect Thomas Hopper worked on its construction, which began in 1819 and reached its magnificent end in the 1850s. His visionary talent gave the castle its characteristic Norman Revival style - a contemporary witness to the architectural greatness of the 19th century. Considered Ulster's largest listed building, the mighty walls of Gosford Castle have witnessed numerous historical turning points. The Earls of Gosford lived here until 1921, after which the castle's fortunes changed. In 1958, the Department of Agriculture acquired the property and transformed the surrounding countryside into the picturesque Gosford Forest Park - a nature lover's paradise spanning 240 hectares where Ireland's flora and fauna flourish in their full glory. But the years were not kind to the castle and it rapidly fell into disrepair. But like a phoenix rising from the ashes, it was acquired by the Boyd Partnership in January 2006. At a cost of around £4 million and under the watchful eye of a government-appointed commission, the castle was lovingly restored and converted into elegant private apartments. Today, Gosford Castle shines in new splendor and attracts admirers from far and wide.
