Rising above the surrounding landscape with its striking tower, St. Brigid's Church tells a story older than its walls suggest. Built between 1927 and 1932, it stands on the foundations of an earlier 18th century church, connecting the past with the present. The stone facades and ornate statues give the building a timeless aura that invites pause. As you walk across the square in front of the church, you feel a certain calm emanating from the old stones. Inside, you'll find a warm atmosphere, with light streaming through the colorful windows and the artistic design of the ceiling and altar. It's a place where you can not only admire the architecture, but also find a moment of reflection - a quiet companion on your walk through the area.

Along Glasdrumman Lough you walk along a calm body of water surrounded by green hills. The lake lies still and reflects the blue sky while the gentle waves break the sunlight. On one side of the road there is a sign telling you about the Poets' Trail - a hiking trail that shares not only the nature but also the history of this region with you. The information board tells you about the nearby O'Neill Castle, of which only ruins remain today. Here you can immerse yourself in the world of old Irish poems and legends that have their place along this trail. It is a place where nature and culture meet.

Due to its privileged location, this incredible Anglo-Norman castle can be seen from miles around. It is believed to have been built in the first half of the 13th century by Lady Rohesia de Verdun after her husband's death. According to legend, she promised to marry the architect who built her a castle in Roche. When this happened and the architect claimed her hand, she threw him from one of the windows, which is known as the 'murder window.'

St. Brigid's is a relatively new church considering the area, as it was constructed between 1927 and 1932, although it was built over another 18th-century church that had previously existed in the area.

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.

Yes, the area offers several accessible options perfect for families. The Ballymoyer Forest loop from Whitecross is an excellent choice, offering a peaceful 4.3-kilometer walk through the woods. Another great option is the View of Lough Muckno – Hope Castle loop from Castleblayney, which provides lovely scenery without being too strenuous.
The Ring of Gullion is an Area of Outstanding Natural Beauty known for its unique geology and rugged, myth-rich landscape. It's a ring dyke formed by a collapsed volcanic caldera. Hikers can expect to find dramatic hills, open moorland, and woodland, with Slieve Gullion as its highest point, offering panoramic views from its summit.
Many trails in the region are suitable for walking with dogs, but it's important to be responsible. Always keep your dog on a lead, especially in areas with livestock like the rural landscapes around County Armagh. Forest parks such as Ravensdale Forest are often popular with dog walkers. Please clean up after your pet to keep the trails enjoyable for everyone.
For those seeking a more demanding trek, the region delivers. The Poets Trails: O'Neill route — Ring of Gullion is a difficult 19.5-kilometer hike that explores the area's volcanic history. Additionally, the ascent to the summit of Slieve Gullion is a rewarding challenge, leading to a Neolithic cairn and incredible views.
Besides the specific routes in this guide, several larger parks and areas are highly regarded by locals for hiking. The Ring of Gullion Area of Outstanding Natural Beauty is a top choice for its stunning scenery and varied trails. For a beautiful riverside walk popular with families, The Fairy Glen in Rostrevor is a local favorite. Silent Valley Mountain Park is another excellent destination, offering multiple walking trails around its famous reservoirs.
Many of the recommended routes in the area are loops, allowing you to start and finish in the same location without retracing your steps. For example, the St. Brigid's Church loop from Creggan is a pleasant circular walk that also takes in some local heritage.
The region is rich in history. On the Slieve Gullion summit trail, you'll find a Neolithic passage tomb, which is the highest surviving of its kind in Ireland. Other trails pass by historical landmarks like the impressive Tassagh Viaduct, a relic of the region's railway history. Many routes are designed to connect you with the area's ancient past.
For a comprehensive list of themed walking trails that cover the 7,500-year history of Armagh, from its ancient origins to its Georgian heritage, you can consult the local tourism resources. The official Visit Armagh trails page provides details on these routes.
Hiking is possible year-round, but spring and summer (April to September) offer the best conditions with longer daylight hours and warmer weather. Spring is particularly beautiful in woodlands like Clare Glen, when the ground is covered in bluebells. Autumn provides stunning colors in the deciduous forests. Winter hiking is possible but requires proper gear for colder, wetter conditions.
While both offer fantastic hiking, they have distinct characteristics. The Mourne Mountains are known for their dramatic, granite peaks and the iconic Mourne Wall, offering more rugged and exposed high-mountain trekking. The Ring of Gullion, a volcanic ring dyke, features rolling hills, heathland, and a deep connection to Irish mythology, with Slieve Gullion as its central peak. The trails here often feel more intertwined with the historical and pastoral landscape.
Most established trailheads and forest parks have dedicated parking areas. For hikes in the Ring of Gullion, there is a car park at the Slieve Gullion Forest Park. For routes around loughs, like Lough Muckno, you will find parking near the main access points in Castleblayney. It's always a good idea to arrive early on weekends as popular spots can fill up.
